==== Save Status and Disconnect ====
* To save the current loading state and enter Sleep Mode:
**: Press and hold the <code>9</code> key for 3 seconds.

==== Selecting a File ====
: To ensure the loading state is maintained after a file is selected, you must save the state manually.
* Please refer to the key operations in the [[#Key Definitions|Key Definitions]] section above.

==== Safely Remove Hardware in OS ====
: If the IODD partition is formatted as NTFS, using the "Safely Remove Hardware" function is mandatory before disconnecting the device from the host.
: NTFS does not always write data to the drive immediately.
* Please use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware] before physical disconnection.

=== Initialization ===
* Initialize the drive using <span class="notranslate">([[wken:MBR]])</span> or <span class="notranslate">([[wken:GPT]])</span> partition styles.
* Format partitions using (NTFS | exFAT | FAT32).
*: '''Note:''' FAT32 partitions have a 4GB file size limit. Please use this format with caution.
*: The partition used by IODD does not necessarily have to be the first partition.
* Copy your files or folders to the IODD.
* Perform a "Safely Remove Hardware" operation (Crucial if using NTFS).
* Reconnect the IODD.
* If the file list on the screen does not match what you copied, press and hold <code>4</code> for 3 seconds to refresh.
*: You can also select the default partition from the list.

=== Troubleshooting ===
: If an error occurs, follow these steps sequentially until the issue is resolved:
# '''Temporary Reset:''' Press and hold <code>7</code> while connecting to the PC.
# '''Factory Reset:''' Press and hold <code>1</code> while connecting to the PC.
# '''Disk Check:''' Run a Disk Check ([[msen:check%20disk | chkdsk]]) on Windows to repair file system errors.
# '''Re-initialization:''' Back up your data and perform the [[#Initialization|Initialization]] process again.

: '''If the issue appears to be hardware-related:'''
# Reboot your PC.
# Try a different USB cable.
# Connect the device to a different PC.
# '''Force Firmware Recovery:''' Connect the device to the PC while holding both <code>9</code> and <code>⏎</code> for 7 seconds.
#: This will re-flash the current firmware to recover the device.

=== Configure Multi Device ===
# Go to ''Menu'' -> ''Mode Setting''.
# Refer to the [[#Menu|Menu]] section for detailed navigation.
# You can configure up to 5 devices independently.

=== Using a Virtual CD Drive (DVD-ROM or Blu-ray ROM) ===
# An ODD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
# Copy your ISO files to the IODD (root or subfolders).
# Use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware]. (This is mandatory for NTFS partitions).
# Reconnect the device.
# Select the desired ISO file.
# To save the loading status for future use, press <code>9</code>.
# If the PC does not detect the boot device, reboot the PC using <span class="notranslate">(Ctrl-Alt-Del)</span>.

==== Booting Error ====
* Verify that the ISO file itself is bootable.
* If your PC does not support Multi-LUN, please configure only one active drive at a time.
* Compare the behavior with a physical USB DVD-ROM to rule out ISO-related issues.
* Use a USB Y-cable to provide auxiliary power, as the IODD is a bus-powered device that may require additional voltage.
* If your laptop has an internal DVD-ROM, disable it in the BIOS settings or remove it physically.
* Older operating systems may lack the necessary drivers to boot on newer motherboards.
** Example: It is generally not possible to install a genuine version of Windows 7 on the Skylake platform using a USB DVD-ROM device.

=== Using a Virtual VHD Drive (Virtual Hard Disk) ===
* At least one VHD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* Please note that not all computers support virtual floppy drives.
* Supports uncompressed floppy disk images (IMA, IMG, BIF, VFD).
* Image files with .IMG, .BIF, or .VFD extensions must be renamed to .IMA to be recognized.
* The usage process is identical to the Virtual CD/VHD methods described above.

** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up to a separate storage medium or cloud service.

*: '''Note:''' FAT32 partitions have a 4GB file size limit. Please use this format with caution.
*: The partition used by IODD does not necessarily have to be the first partition.
* Copy your files or folders to the IODD.
* Perform a "Safely Remove Hardware" operation (Crucial if using NTFS).
* Reconnect the IODD.
* If the file list on the screen does not match what you copied, press and hold <code>4</code> for 3 seconds to refresh.
*: You can also select the default partition from the list.

=== Troubleshooting ===
: If an error occurs, follow these steps sequentially until the issue is resolved:
# '''Admin/User Login:''' If your password is '1234', enter '01234' for Admin (ID '0') or '11234' for User 1 (ID '1').
#: The first digit represents the User ID: Admin is '0', Users are '1'–'4'.
# '''Temporary Reset:''' Press and hold <code>7</code> while connecting to the PC.
# '''Factory Reset:''' Press and hold <code>1</code> while connecting to the PC.
# '''Disk Check:''' Run a Disk Check ([[msen:check%20disk | chkdsk]]) on Windows to repair file system errors.
# '''Re-initialization:''' Back up your data and perform the [[#Initialization|Initialization]] process again.

: '''If the issue appears to be hardware-related:'''
# Reboot your PC.
# Try a different USB cable.
# Connect the device to a different PC.
# '''Force Firmware Recovery:''' Connect the device to the PC while holding both <code>9</code> and <code>⏎</code> for 7 seconds.
#: This will re-flash the current firmware to recover the device.

=== Configure Multi Device ===
# Go to ''Menu'' -> ''Mode Setting''.
# Refer to the [[#Menu|Menu]] section for detailed navigation.
# You can configure up to 5 devices independently.

=== Using a Virtual CD Drive (DVD-ROM or Blu-ray ROM) ===
# An ODD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
# Copy your ISO files to the IODD (root or subfolders).
# Use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware]. (This is mandatory for NTFS partitions).
# Reconnect the device.
# Select the desired ISO file.
# To save the loading status for future use, press <code>9</code>.
# If the PC does not detect the boot device, reboot the PC using <span class="notranslate">(Ctrl-Alt-Del)</span>.

==== Booting Error ====
* Verify that the ISO file itself is bootable.
* If your PC does not support Multi-LUN, please configure only one active drive at a time.
* Compare the behavior with a physical USB DVD-ROM to rule out ISO-related issues.
* Use a USB Y-cable to provide auxiliary power, as the IODD is a bus-powered device that may require additional voltage.
* If your laptop has an internal DVD-ROM, disable it in the BIOS settings or remove it physically.
* Older operating systems may lack the necessary drivers to boot on newer motherboards.
** Example: It is generally not possible to install a genuine version of Windows 7 on the Skylake platform using a USB DVD-ROM device.

=== Using a Virtual VHD Drive (Virtual Hard Disk) ===
* At least one VHD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* Please note that not all computers support virtual floppy drives.
* Supports uncompressed floppy disk images (IMA, IMG, BIF, VFD).
* Image files with .IMG, .BIF, or .VFD extensions must be renamed to .IMA to be recognized.
* The usage process is identical to the Virtual CD/VHD methods described above.

== Precautions ==

* '''Caution: Insufficient Power Supply'''
** USB bus-powered devices consume significant power. Connect the device directly to the motherboard USB ports (on the rear of the PC) whenever possible.
** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up to a separate storage medium or cloud service.

* If you use FAT32 or exFAT Partition, then run FAT Firmware Updater. ([[msen:FAT32|FAT32]] [[wken:exFAT|exFAT]] [[msen:Partition|Partition]])
* follow the next steps
# assemble the HDD or SSD with iODD
# connect the iODD to PC
# initialize the drive to MBR. <span class="notranslate">([[wken:MBR]])</span>
# Format the first partition as NTFS. (if the firmware is FAT, then format it as FAT32 or exFAT)
#* In FAT32 partition there is 4G byte file size limitation. please use that carefully.
# create "_ISO" folder in root folder. (not case sensitive)
# copy ISO file to "_ISO" folder. (or create VHD RMD IMA files)
# safely remove iODD. ( very '''Important''' if NTFS). ([http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer safely remove]).
# If Power Saving mode is active, then disconnect and reconnect the USB cable.
#* If not, then [[#Go to Power Saving State|Go to Power Saving State]]
#* If <span class="notranslate">"Plug Out ..."</span> (or "Plug Out ...") message appears, reconnect the USB cable.
# The following messages will appear sequentially in LCD
#* <span class="notranslate">"iodd 253(4)1"</span>
#* a file name

==== Initialize All ====
:If [[#Initialization|Initialization]] fails, follow the next steps
# disconnect the USB cable.
# remove the HDD from iODD. and Connect directly it to PC.
# Initialize it to GPT. <span class="notranslate">([[msen:GPT]])</span>
# redo [[#Initialization|Initialization]] (from the first step). (your HDD is initialized as <span class="notranslate">MBR -> GPT -> MBR)</span>.
# Open back cover
# Press tact switch
# Connect USB cable
# Wait 7 seconds
# Release tact switch
# Wait 1 minutes
# All done

=== First Aid ===
: If it has failure suddenly, try one of the following steps until the error is clear

# try [[#Safely Removal In OS|Safely Removal In OS]].
# Check Disk for iODD ([[msen:check%20disk | for Windows]])
# Rename "_ISO" folder name to other name. create new folder named "_ISO". and copy files to this folder. (not moving)
# Backup the data of iODD, and [[#Initialize All|Initialize All]]
: If there is hardware problem
# Reboot the PC
# Please change USB cable
# Connect iODD to the port of PC back panel.
# Try it on another pc
# Please change the HDD.

=== Using a Virtual USB Optical Drive (DVD-ROM or Blu-ray ROM) ===
# copy ISO files to "_ISO" folder. (or to subfolder)
# [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove]. (Required for NTFS )
# If Power Saving mode is not active , then [[#Go to Power Saving State|Go to Power Saving State]]
#* If <span class="notranslate">"Plug Out ..."</span> (or "Plug Out ...") message appears, disconnect the iODD.
# Connect iODD to a PC. and power on the PC.
# (Optional) select iODD or USB CD-ROM as the first priority of BOOT order in BIOS.
# If a file has not been selected, then select an ISO file. [[#Selecting a file|Selecting a file]]
# If PC doesn't find boot device, then reboot the PC. <span class="notranslate">(Ctrl-Alt-Del)<span>

==== Booting Error ====
* Confirm whether the ISO file is bootable.
* If your PC does not support multi LUN, please select CD-MODE (or ODD-MODE).
* In order to confirm whether the ISO file is able to boot, please try to test it with the validated PC.
* Although it is bootable ISO file, please confirm whether the result with a real USB DVD-ROM is the same
* If the ISO file can be boot with USB DVD-ROM, then use USB Y-CABLE for adding external power.
* If your laptop has own internal DVD-ROM, please disable internal DVD-ROM at BIOS settings. or remove it.
* The older OS than motherboard may not have an appropriate driver to boot.
** ex) It is impossible to install a genuine Windows 7 on Skylake platform using USB DVD-ROM device.

=== Using a Virtual USB fixed disk drive (Virtual Hard Disk) ===
* Fixed-size VHD file only is supported. (dynamic VHD and VHDx files are not supported)
* Also fixed [[wken:VMDK|VMDK]] file is supported.
* Create VHD files directly to iODD by [[VHD Tool++|"VHD Tool++"]]. ("VHD Tool++" can creates a file without fragment)
* You can create VMDK by changing file extension. <span class="notranslate">(VHD -> VMDK)<span>.
* If you select a VHD file, then iODD will be rebooted with CD-MODE. and it will be recognized as a USB disk drive.([[#Selecting a file|Selecting a file]]).
* If you want to change to DUAL-MODE or to change Write Protection option, rename the VHD filename. refer to [[VHD Tool++|"VHD Tool++"]]
* Max 4 Virtual Drives are supported at the same time ( Successive selection within 3 seconds)
# create a VHD file using a tool. ([[VHD Tool++|VHD Tool++]]).
# If successful, safely remove iODD from OS. ([[#Safely Removal In OS]]. Very Important to NTFS.)
# If Power Saving mode is not active, then [[#Go to Power Saving State|Go to Power Saving State]]
#* If <span class="notranslate">"Plug Out ..."</span> (or "Plug Out ...") message appear, disconnect the iODD.
# Connect iODD to a PC. and power on the PC.
# (Optional) select iODD or USB Device as the first priority of BOOT order in BIOS.
# If a file has not been selected, then select a VHD file. ([[#Selecting a file|Selecting a file]])
# If PC doesn't find boot device, then reboot the PC. <span class="notranslate">(Ctrl-Alt-Del)<span>

=== Using a Virtual USB Removable Flash Drive (Virtual USB Flash Drive) ===
* Almost the same as the above method. (Using a Virtual USB fixed disk drive)
* But the file extension must be changed. "VHD" -> "RMD"

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* This method is not supported on some computers.
* Uncompressed floppy image IMA, IMG, BIF, VFD are supported.
* IMG, BIF, VFD image file extension must be renamed to IMA.
* Almost the same as the above method.

==== Safely Remove Hardware in OS ====
: If the IODD partition is formatted as NTFS, using the "Safely Remove Hardware" function is mandatory before disconnecting the device from the host.
: NTFS does not always write data to the drive immediately.
* Please use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware] before physical disconnection.

=== Initialization ===
* Initialize the drive using <span class="notranslate">([[wken:MBR]])</span> or <span class="notranslate">([[wken:GPT]])</span> partition styles.
* Format partitions using (NTFS | exFAT | FAT32).
*: '''Note:''' FAT32 partitions have a 4GB file size limit. Please use this format with caution.
*: The partition used by IODD does not necessarily have to be the first partition.
* Copy your files or folders to the IODD.
* Perform a "Safely Remove Hardware" operation (Crucial if using NTFS).
* Reconnect the IODD.
* If the file list on the screen does not match what you copied, press and hold <code>4</code> for 3 seconds to refresh.
*: You can also select the default partition from the list.

=== Troubleshooting ===
: If an error occurs, follow these steps sequentially until the issue is resolved:
# '''Admin/User Login:''' If your password is '1234', enter '01234' for Admin (ID '0') or '11234' for User 1 (ID '1').
#: The first digit represents the User ID: Admin is '0', Users are '1'–'4'.
# '''Temporary Reset:''' Press and hold <code>7</code> while connecting to the PC.
# '''Factory Reset:''' Press and hold <code>1</code> while connecting to the PC.
# '''Disk Check:''' Run a Disk Check ([[msen:check%20disk | chkdsk]]) on Windows to repair file system errors.
# '''Re-initialization:''' Back up your data and perform the [[#Initialization|Initialization]] process again.

: '''If the issue appears to be hardware-related:'''
# Reboot your PC.
# Try a different USB cable.
# Connect the device to a different PC.
# '''Force Firmware Recovery:''' Connect the device to the PC while holding both <code>9</code> and <code>⏎</code> for 7 seconds.
#: This will re-flash the current firmware to recover the device.

=== Configure Multi Device ===
# Go to ''Menu'' -> ''Mode Setting''.
# Refer to the [[#Menu|Menu]] section for detailed navigation.
# You can configure up to 5 devices independently.

=== Using a Virtual CD Drive (DVD-ROM or Blu-ray ROM) ===
# An ODD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
# Copy your ISO files to the IODD (root or subfolders).
# Use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware]. (This is mandatory for NTFS partitions).
# Reconnect the device.
# Select the desired ISO file.
# To save the loading status for future use, press <code>9</code>.
# If the PC does not detect the boot device, reboot the PC using <span class="notranslate">(Ctrl-Alt-Del)</span>.

==== Booting Error ====
* Verify that the ISO file itself is bootable.
* If your PC does not support Multi-LUN, please configure only one active drive at a time.
* Compare the behavior with a physical USB DVD-ROM to rule out ISO-related issues.
* Use a USB Y-cable to provide auxiliary power, as the IODD is a bus-powered device that may require additional voltage.
* If your laptop has an internal DVD-ROM, disable it in the BIOS settings or remove it physically.
* Older operating systems may lack the necessary drivers to boot on newer motherboards.
** Example: It is generally not possible to install a genuine version of Windows 7 on the Skylake platform using a USB DVD-ROM device.

=== Using a Virtual VHD Drive (Virtual Hard Disk) ===
* At least one VHD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* Please note that not all computers support virtual floppy drives.
* Supports uncompressed floppy disk images (IMA, IMG, BIF, VFD).
* Image files with .IMG, .BIF, or .VFD extensions must be renamed to .IMA to be recognized.
* The usage process is identical to the Virtual CD/VHD methods described above.

** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up to a separate storage medium or cloud service.

* Please refer to the key operations in the [[#Key Definitions|Key Definitions]] section above.

==== Safely Remove Hardware in OS ====
: If the IODD partition is formatted as NTFS, using the "Safely Remove Hardware" function is mandatory before disconnecting the device from the host.
: NTFS does not always write data to the drive immediately.
* Please use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware] before physical disconnection.

=== Initialization ===
* Initialize the drive using <span class="notranslate">([[wken:MBR]])</span> or <span class="notranslate">([[wken:GPT]])</span> partition styles.
* Format partitions using (NTFS | exFAT | FAT32).
*: '''Note:''' FAT32 partitions have a 4GB file size limit. Please use this format with caution.
*: The partition used by IODD does not necessarily have to be the first partition.
* Copy your files or folders to the IODD.
* Perform a "Safely Remove Hardware" operation (Crucial if using NTFS).
* Reconnect the IODD.
* If the file list on the screen does not match what you copied, press and hold <code>4</code> for 3 seconds to refresh.
*: You can also select the default partition from the list.

=== Troubleshooting ===
: If an error occurs, follow these steps sequentially until the issue is resolved:
# '''Admin/User Login:''' If your password is '1234', enter '01234' for Admin (ID '0') or '11234' for User 1 (ID '1').
#: The first digit represents the User ID: Admin is '0', Users are '1'–'4'.
# '''Temporary Reset:''' Press and hold <code>7</code> while connecting to the PC.
# '''Factory Reset:''' Press and hold <code>1</code> while connecting to the PC.
# '''Disk Check:''' Run a Disk Check ([[msen:check%20disk | chkdsk]]) on Windows to repair file system errors.
# '''Re-initialization:''' Back up your data and perform the [[#Initialization|Initialization]] process again.

: '''If the issue appears to be hardware-related:'''
# Reboot your PC.
# Try a different USB cable.
# Connect the device to a different PC.
# '''Force Firmware Recovery:''' Connect the device to the PC while holding both <code>9</code> and <code>⏎</code> for 7 seconds.
#: This will re-flash the current firmware to recover the device.

=== Configure Multi Device ===
# Go to ''Menu'' -> ''Mode Setting''.
# Refer to the [[#Menu|Menu]] section for detailed navigation.
# You can configure up to 5 devices independently.

=== Using a Virtual CD Drive (DVD-ROM or Blu-ray ROM) ===
# An ODD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
# Copy your ISO files to the IODD (root or subfolders).
# Use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware]. (This is mandatory for NTFS partitions).
# Reconnect the device.
# Select the desired ISO file.
# To save the loading status for future use, press <code>9</code>.
# If the PC does not detect the boot device, reboot the PC using <span class="notranslate">(Ctrl-Alt-Del)</span>.

==== Booting Error ====
* Verify that the ISO file itself is bootable.
* If your PC does not support Multi-LUN, please configure only one active drive at a time.
* Compare the behavior with a physical USB DVD-ROM to rule out ISO-related issues.
* Use a USB Y-cable to provide auxiliary power, as the IODD is a bus-powered device that may require additional voltage.
* If your laptop has an internal DVD-ROM, disable it in the BIOS settings or remove it physically.
* Older operating systems may lack the necessary drivers to boot on newer motherboards.
** Example: It is generally not possible to install a genuine version of Windows 7 on the Skylake platform using a USB DVD-ROM device.

=== Using a Virtual VHD Drive (Virtual Hard Disk) ===
* At least one VHD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* Please note that not all computers support virtual floppy drives.
* Supports uncompressed floppy disk images (IMA, IMG, BIF, VFD).
* Image files with .IMG, .BIF, or .VFD extensions must be renamed to .IMA to be recognized.
* The usage process is identical to the Virtual CD/VHD methods described above.

== Precautions ==

* '''Caution: Insufficient Power Supply'''
** USB bus-powered devices consume significant power. Connect the device directly to the motherboard USB ports (on the rear of the PC) whenever possible.
** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up to a separate storage medium or cloud service.

**: Press and hold the <code>9</code> key for 3 seconds.

==== Selecting a File ====
: To ensure the loading state is maintained after a file is selected, you must save the state manually.
* Please refer to the key operations in the [[#Key Definitions|Key Definitions]] section above.

==== Safely Remove Hardware in OS ====
: If the IODD partition is formatted as NTFS, using the "Safely Remove Hardware" function is mandatory before disconnecting the device from the host.
: NTFS does not always write data to the drive immediately.
* Please use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware] before physical disconnection.

=== Initialization ===
* Initialize the drive using <span class="notranslate">([[wken:MBR]])</span> or <span class="notranslate">([[wken:GPT]])</span> partition styles.
* Format partitions using (NTFS | exFAT | FAT32).
*: '''Note:''' FAT32 partitions have a 4GB file size limit. Please use this format with caution.
*: The partition used by IODD does not necessarily have to be the first partition.
* Copy your files or folders to the IODD.
* Perform a "Safely Remove Hardware" operation (Crucial if using NTFS).
* Reconnect the IODD.
* If the file list on the screen does not match what you copied, press and hold <code>4</code> for 3 seconds to refresh.
*: You can also select the default partition from the list.

=== Troubleshooting ===
: If an error occurs, follow these steps sequentially until the issue is resolved:
# '''Temporary Reset:''' Press and hold <code>7</code> while connecting to the PC.
# '''Factory Reset:''' Press and hold <code>1</code> while connecting to the PC.
# '''Disk Check:''' Run a Disk Check ([[msen:check%20disk | chkdsk]]) on Windows to repair file system errors.
# '''Re-initialization:''' Back up your data and perform the [[#Initialization|Initialization]] process again.

: '''If the issue appears to be hardware-related:'''
# Reboot your PC.
# Try a different USB cable.
# Connect the device to a different PC.
# '''Force Firmware Recovery:''' Connect the device to the PC while holding both <code>9</code> and <code>⏎</code> for 7 seconds.
#: This will re-flash the current firmware to recover the device.

=== Configure Multi Device ===
# Go to ''Menu'' -> ''Mode Setting''.
# Refer to the [[#Menu|Menu]] section for detailed navigation.
# You can configure up to 5 devices independently.

=== Using a Virtual CD Drive (DVD-ROM or Blu-ray ROM) ===
# An ODD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
# Copy your ISO files to the IODD (root or subfolders).
# Use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware]. (This is mandatory for NTFS partitions).
# Reconnect the device.
# Select the desired ISO file.
# To save the loading status for future use, press <code>9</code>.
# If the PC does not detect the boot device, reboot the PC using <span class="notranslate">(Ctrl-Alt-Del)</span>.

==== Booting Error ====
* Verify that the ISO file itself is bootable.
* If your PC does not support Multi-LUN, please configure only one active drive at a time.
* Compare the behavior with a physical USB DVD-ROM to rule out ISO-related issues.
* Use a USB Y-cable to provide auxiliary power, as the IODD is a bus-powered device that may require additional voltage.
* If your laptop has an internal DVD-ROM, disable it in the BIOS settings or remove it physically.
* Older operating systems may lack the necessary drivers to boot on newer motherboards.
** Example: It is generally not possible to install a genuine version of Windows 7 on the Skylake platform using a USB DVD-ROM device.

=== Using a Virtual VHD Drive (Virtual Hard Disk) ===
* At least one VHD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* Please note that not all computers support virtual floppy drives.
* Supports uncompressed floppy disk images (IMA, IMG, BIF, VFD).
* Image files with .IMG, .BIF, or .VFD extensions must be renamed to .IMA to be recognized.
* The usage process is identical to the Virtual CD/VHD methods described above.

== Precautions ==

* '''Caution: Insufficient Power Supply'''
** USB bus-powered devices consume significant power. Connect the device directly to the motherboard USB ports (on the rear of the PC) whenever possible.
** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up to a separate storage medium or cloud service.

* To save the current loading state and enter Sleep Mode:
**: Press and hold the <code>9</code> key for 3 seconds.

==== Selecting a File ====
: To ensure the loading state is maintained after a file is selected, you must save the state manually.
* Please refer to the key operations in the [[#Key Definitions|Key Definitions]] section above.

==== Safely Remove Hardware in OS ====
: If the IODD partition is formatted as NTFS, using the "Safely Remove Hardware" function is mandatory before disconnecting the device from the host.
: NTFS does not always write data to the drive immediately.
* Please use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware] before physical disconnection.

=== Initialization ===
* Initialize the drive using <span class="notranslate">([[wken:MBR]])</span> or <span class="notranslate">([[wken:GPT]])</span> partition styles.
* Format partitions using (NTFS | exFAT | FAT32).
*: '''Note:''' FAT32 partitions have a 4GB file size limit. Please use this format with caution.
*: The partition used by IODD does not necessarily have to be the first partition.
* Copy your files or folders to the IODD.
* Perform a "Safely Remove Hardware" operation (Crucial if using NTFS).
* Reconnect the IODD.
* If the file list on the screen does not match what you copied, press and hold <code>4</code> for 3 seconds to refresh.
*: You can also select the default partition from the list.

=== Troubleshooting ===
: If an error occurs, follow these steps sequentially until the issue is resolved:
# '''Admin/User Login:''' If your password is '1234', enter '01234' for Admin (ID '0') or '11234' for User 1 (ID '1').
#: The first digit represents the User ID: Admin is '0', Users are '1'–'4'.
# '''Temporary Reset:''' Press and hold <code>7</code> while connecting to the PC.
# '''Factory Reset:''' Press and hold <code>1</code> while connecting to the PC.
# '''Disk Check:''' Run a Disk Check ([[msen:check%20disk | chkdsk]]) on Windows to repair file system errors.
# '''Re-initialization:''' Back up your data and perform the [[#Initialization|Initialization]] process again.

: '''If the issue appears to be hardware-related:'''
# Reboot your PC.
# Try a different USB cable.
# Connect the device to a different PC.
# '''Force Firmware Recovery:''' Connect the device to the PC while holding both <code>9</code> and <code>⏎</code> for 7 seconds.
#: This will re-flash the current firmware to recover the device.

=== Configure Multi Device ===
# Go to ''Menu'' -> ''Mode Setting''.
# Refer to the [[#Menu|Menu]] section for detailed navigation.
# You can configure up to 5 devices independently.

=== Using a Virtual CD Drive (DVD-ROM or Blu-ray ROM) ===
# An ODD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
# Copy your ISO files to the IODD (root or subfolders).
# Use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware]. (This is mandatory for NTFS partitions).
# Reconnect the device.
# Select the desired ISO file.
# To save the loading status for future use, press <code>9</code>.
# If the PC does not detect the boot device, reboot the PC using <span class="notranslate">(Ctrl-Alt-Del)</span>.

==== Booting Error ====
* Verify that the ISO file itself is bootable.
* If your PC does not support Multi-LUN, please configure only one active drive at a time.
* Compare the behavior with a physical USB DVD-ROM to rule out ISO-related issues.
* Use a USB Y-cable to provide auxiliary power, as the IODD is a bus-powered device that may require additional voltage.
* If your laptop has an internal DVD-ROM, disable it in the BIOS settings or remove it physically.
* Older operating systems may lack the necessary drivers to boot on newer motherboards.
** Example: It is generally not possible to install a genuine version of Windows 7 on the Skylake platform using a USB DVD-ROM device.

=== Using a Virtual VHD Drive (Virtual Hard Disk) ===
* At least one VHD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* Please note that not all computers support virtual floppy drives.
* Supports uncompressed floppy disk images (IMA, IMG, BIF, VFD).
* Image files with .IMG, .BIF, or .VFD extensions must be renamed to .IMA to be recognized.
* The usage process is identical to the Virtual CD/VHD methods described above.

== Precautions ==

* '''Caution: Insufficient Power Supply'''
** USB bus-powered devices consume significant power. Connect the device directly to the motherboard USB ports (on the rear of the PC) whenever possible.
** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up to a separate storage medium or cloud service.

* Format partitions using (NTFS | exFAT | FAT32).
*: '''Note:''' FAT32 partitions have a 4GB file size limit. Please use this format with caution.
*: The partition used by IODD does not necessarily have to be the first partition.
* Copy your files or folders to the IODD.
* Perform a "Safely Remove Hardware" operation (Crucial if using NTFS).
* Reconnect the IODD.
* If the file list on the screen does not match what you copied, press and hold <code>4</code> for 3 seconds to refresh.
*: You can also select the default partition from the list.

=== Troubleshooting ===
: If an error occurs, follow these steps sequentially until the issue is resolved:
# '''Admin/User Login:''' If your password is '1234', enter '01234' for Admin (ID '0') or '11234' for User 1 (ID '1').
#: The first digit represents the User ID: Admin is '0', Users are '1'–'4'.
# '''Temporary Reset:''' Press and hold <code>7</code> while connecting to the PC.
# '''Factory Reset:''' Press and hold <code>1</code> while connecting to the PC.
# '''Disk Check:''' Run a Disk Check ([[msen:check%20disk | chkdsk]]) on Windows to repair file system errors.
# '''Re-initialization:''' Back up your data and perform the [[#Initialization|Initialization]] process again.

: '''If the issue appears to be hardware-related:'''
# Reboot your PC.
# Try a different USB cable.
# Connect the device to a different PC.
# '''Force Firmware Recovery:''' Connect the device to the PC while holding both <code>9</code> and <code>⏎</code> for 7 seconds.
#: This will re-flash the current firmware to recover the device.

=== Configure Multi Device ===
# Go to ''Menu'' -> ''Mode Setting''.
# Refer to the [[#Menu|Menu]] section for detailed navigation.
# You can configure up to 5 devices independently.

=== Using a Virtual CD Drive (DVD-ROM or Blu-ray ROM) ===
# An ODD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
# Copy your ISO files to the IODD (root or subfolders).
# Use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware]. (This is mandatory for NTFS partitions).
# Reconnect the device.
# Select the desired ISO file.
# To save the loading status for future use, press <code>9</code>.
# If the PC does not detect the boot device, reboot the PC using <span class="notranslate">(Ctrl-Alt-Del)</span>.

==== Booting Error ====
* Verify that the ISO file itself is bootable.
* If your PC does not support Multi-LUN, please configure only one active drive at a time.
* Compare the behavior with a physical USB DVD-ROM to rule out ISO-related issues.
* Use a USB Y-cable to provide auxiliary power, as the IODD is a bus-powered device that may require additional voltage.
* If your laptop has an internal DVD-ROM, disable it in the BIOS settings or remove it physically.
* Older operating systems may lack the necessary drivers to boot on newer motherboards.
** Example: It is generally not possible to install a genuine version of Windows 7 on the Skylake platform using a USB DVD-ROM device.

=== Using a Virtual VHD Drive (Virtual Hard Disk) ===
* At least one VHD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* Please note that not all computers support virtual floppy drives.
* Supports uncompressed floppy disk images (IMA, IMG, BIF, VFD).
* Image files with .IMG, .BIF, or .VFD extensions must be renamed to .IMA to be recognized.
* The usage process is identical to the Virtual CD/VHD methods described above.

== Precautions ==

* '''Caution: Insufficient Power Supply'''
** USB bus-powered devices consume significant power. Connect the device directly to the motherboard USB ports (on the rear of the PC) whenever possible.
** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up to a separate storage medium or cloud service.

== Precautions ==

* '''Caution: Insufficient Power Supply'''
** USB bus-powered devices consume significant power. Connect the device directly to the motherboard USB ports (on the rear of the PC) whenever possible.
** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''

* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Initialization ===
* Initialize the drive using <span class="notranslate">([[wken:MBR]])</span> or <span class="notranslate">([[wken:GPT]])</span> partition styles.
* Format partitions using (NTFS | exFAT | FAT32).
*: '''Note:''' FAT32 partitions have a 4GB file size limit. Please use this format with caution.
*: The partition used by IODD does not necessarily have to be the first partition.
* Copy your files or folders to the IODD.
* Perform a "Safely Remove Hardware" operation (Crucial if using NTFS).
* Reconnect the IODD.
* If the file list on the screen does not match what you copied, press and hold <code>4</code> for 3 seconds to refresh.
*: You can also select the default partition from the list.

=== Troubleshooting ===
: If an error occurs, follow these steps sequentially until the issue is resolved:
# '''Admin/User Login:''' If your password is '1234', enter '01234' for Admin (ID '0') or '11234' for User 1 (ID '1').
#: The first digit represents the User ID: Admin is '0', Users are '1'–'4'.
# '''Temporary Reset:''' Press and hold <code>7</code> while connecting to the PC.
# '''Factory Reset:''' Press and hold <code>1</code> while connecting to the PC.
# '''Disk Check:''' Run a Disk Check ([[msen:check%20disk | chkdsk]]) on Windows to repair file system errors.
# '''Re-initialization:''' Back up your data and perform the [[#Initialization|Initialization]] process again.

: '''If the issue appears to be hardware-related:'''
# Reboot your PC.
# Try a different USB cable.
# Connect the device to a different PC.
# '''Force Firmware Recovery:''' Connect the device to the PC while holding both <code>9</code> and <code>⏎</code> for 7 seconds.
#: This will re-flash the current firmware to recover the device.

=== Configure Multi Device ===
# Go to ''Menu'' -> ''Mode Setting''.
# Refer to the [[#Menu|Menu]] section for detailed navigation.
# You can configure up to 5 devices independently.

=== Using a Virtual CD Drive (DVD-ROM or Blu-ray ROM) ===
# An ODD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
# Copy your ISO files to the IODD (root or subfolders).
# Use [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove Hardware]. (This is mandatory for NTFS partitions).
# Reconnect the device.
# Select the desired ISO file.
# To save the loading status for future use, press <code>9</code>.
# If the PC does not detect the boot device, reboot the PC using <span class="notranslate">(Ctrl-Alt-Del)</span>.

==== Booting Error ====
* Verify that the ISO file itself is bootable.
* If your PC does not support Multi-LUN, please configure only one active drive at a time.
* Compare the behavior with a physical USB DVD-ROM to rule out ISO-related issues.
* Use a USB Y-cable to provide auxiliary power, as the IODD is a bus-powered device that may require additional voltage.
* If your laptop has an internal DVD-ROM, disable it in the BIOS settings or remove it physically.
* Older operating systems may lack the necessary drivers to boot on newer motherboards.
** Example: It is generally not possible to install a genuine version of Windows 7 on the Skylake platform using a USB DVD-ROM device.

=== Using a Virtual VHD Drive (Virtual Hard Disk) ===
* At least one VHD device must be enabled. (See [[#Configure Multi Device|Configure Multi Device]])
* '''Important:''' Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
* Fixed-size [[wken:VMDK|VMDK]] files are also supported.
* It is highly recommended to create VHD files directly on the IODD using [[VHD Tool++|"VHD Tool++"]], as it ensures files are created without fragmentation.
* If you copy an existing VHD file, it must be unfragmented to function correctly.
* Up to 3 VHD drives can be mounted simultaneously.

# Create a VHD file using [[VHD Tool++|VHD Tool++]].
# Reconnect the device.
# Select the VHD file from the list.
# To save the loading status, press <code>9</code>.
# Use an imaging tool to apply an OS image to the virtual VHD drive.

=== Using a Virtual USB Floppy Drive (Virtual FDD) ===
* Please note that not all computers support virtual floppy drives.
* Supports uncompressed floppy disk images (IMA, IMG, BIF, VFD).
* Image files with .IMG, .BIF, or .VFD extensions must be renamed to .IMA to be recognized.
* The usage process is identical to the Virtual CD/VHD methods described above.

== Precautions ==

* '''Caution: Insufficient Power Supply'''
** USB bus-powered devices consume significant power. Connect the device directly to the motherboard USB ports (on the rear of the PC) whenever possible.
** Using front panel USB ports or unpowered USB hubs may lead to recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can corrupt the file system. Always use the "Safely Remove Hardware" function in your operating system.
** For IODD products, it is safest to unmount the disk using the device's built-in "Safe Removal" menu or function before physical disconnection.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-based models, there is a high risk of permanent data loss due to read/write head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable provided with the device. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on public PCs where virus infection is a concern, enable the IODD "Write Protect" feature to safeguard your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up to a separate storage medium or cloud service.

== Precautions ==

* '''Caution: Insufficient Power Supply'''
** Products powered by USB bus power have high power consumption. Whenever possible, connect the device directly to the motherboard USB ports on the back of the PC.
** Using front USB ports or unpowered USB hubs may cause recognition failure or data corruption due to insufficient power.
* '''Safe Removal Recommended'''
** Disconnecting the cable while data is being written can destroy the file system. Always use the 'Safely Remove Hardware' function of your operating system.
** For IODD products, it is safest to unmount the disk using the device's own 'Safe Removal' menu or function before disconnecting.
* '''Physical Shock Warning'''
** Do not drop the product or subject it to strong impacts during operation. For HDD-type models in particular, there is a high risk of data loss due to head damage.
* '''Use High-Quality Cables'''
** It is recommended to use the original cable that meets data transmission standards. Cables that are too long or of low quality can cause voltage drops, leading to malfunctions.
* '''Utilize Write-Protect Mode (IODD Specific)'''
** When using the device on a public PC where virus infection is a concern, enable the IODD 'Write Protect' feature to protect your data.
* '''Backups are Essential'''
** Storage devices are consumables. Please ensure that important data is backed up twice to a separate storage medium or cloud service.

== Firmware ==

=== How to update ===
: Requirements : PC ( Windows OS, USB Port)
: '''Warning''' - You must connect only one IODD device.
: Please update the exact firmware that matches IODD.
: If you update wrong firmware, retry with correct firmware.
: '''※ Note:''' The device is designed to prevent "bricking" (becoming unusable) even if an unexpected error occurs during the update. You may proceed with the process with peace of mind.
# Download the firmware file.
# Uncompress the zip file to proper folder.(Do not run it within zip file)
# Run the <span class="notranslate">EXE</span> file.
# If <span class="notranslate">"Device is Detected"</span> message appears, then press <span class="notranslate">"Update"</span> button.
#* If not, follow the steps below.
#* Use another computer.
#* Change the USB cable.
# The update process takes approximately 2-3 minutes. If the screen flickers, please wait and DO NOT disconnect the USB cable.
# If the update finishes without the screen flickering (this may happen if the firmware version is the same), use the following method:
# Press and hold both the <code>9</code> and <code>⏎ (Enter)</code> buttons simultaneously while connecting the USB cable. Continue holding the buttons for at least 7 seconds to force the update with the same firmware version.

* Please do [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Removal] before disconnection.

=== Initialization ===
* Initialize the drive with <span class="notranslate">([[wken:MBR]])</span> or <span class="notranslate">([[wken:GPT]])</span>.
* Format any partition to use with (NTFS | EXFAT | FAT32).
*: In FAT32 partition, there is 4G byte file size limitation. please use that carefully.
*: The Partition may not be first partition.
* Copy files or folders to Iodd.
* safely remove ioddMini. ( very '''Important''' if NTFS). ([http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer safely remove]).
* Reconnect Iodd.
* If the screen is not matched what you copyed, Press <code>4</code> for 3 seconds.
*: You can select the default partition.

=== Troubleshooting ===
: Follow these steps until the error is clear.
# If your password is '1234', type '0' + '1234' at the password input screen.

==== Booting Error ====
* Confirm whether the ISO file is bootable.
* If your PC does not support multi LUN, please configure only one drive.
* Confirm whether the ISO file is bootable.
* Although it is bootable ISO file, please confirm whether the result with a real USB DVD-ROM is same.
* Try with USB Y-CABLE for adding external power. (ioddMini is a class of BUS powered USB device.
* If your laptop has own internal DVD-ROM, disable internal DVD-ROM at BIOS settings. or remove it.
* The older OS than motherboard may not have an appropriate driver to boot.
** ex) It is impossible to install a genuine Windows 7 on Skylake platform using USB DVD-ROM device.
