Selecting a file

In order to maintain loading state, you must save the state.

refer to the above key operations.

• (2531) #2531 Keys
  • If Firmware version is 1558 or higher, loading state is automatically saved.
  • If not, you must save it manually. (Go to Power Saving State)
• (2541) #2541 Keys
  • If Firmware version is lower than 6(7)9-05, button 6 has no function.

Safely Removal In OS

If iODD's partition is NTFS, then this function is mandatory when disconnecting iODD from host.

NTFS does not write Immediately the data to HDD.

• Please do Safely Removal before disconnection.
• If iODD is in write-protected mode and an error message appears, then disable write-protect option. and retry this function.

Initialization

• the firmware is two sorts. (NTFS type, FAT32/exFAT type)
• NTFS firmware version is shipped.
• If you use FAT32 or exFAT Partition, then run FAT Firmware Updater. (FAT32 exFAT Partition)
• follow the next steps

1. assemble the HDD or SSD with iODD
2. connect the iODD to PC
3. initialize the drive to MBR. (wken:MBR)
4. 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.
5. create "_ISO" folder in root folder. (not case sensitive)
6. copy ISO file to "_ISO" folder. (or create VHD RMD IMA files)
7. safely remove iODD. ( very Important if NTFS). (safely remove).
8. If Power Saving mode is active, then disconnect and reconnect the USB cable.
   • If not, then Go to Power Saving State
   • If "Plug Out ..." (or "Plug Out ...") message appears, reconnect the USB cable.
9. The following messages will appear sequentially in LCD
   • "iodd 253(4)1"
   • a file name

Initialize All

If Initialization fails, follow the next steps

1. disconnect the USB cable.
2. remove the HDD from iODD. and Connect directly it to PC.
3. Initialize it to GPT. (msen:GPT)
4. redo Initialization (from the first step). (your HDD is initialized as MBR -> GPT -> MBR).
5. Open back cover
6. Press tact switch
7. Connect USB cable
8. Wait 7 seconds
9. Release tact switch
10. Wait 1 minutes
11. All done

First Aid

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

1. (2531). press the Jog Dial and hold. and then connect iODD to PC. (#2531 Keys. refer to Startup Keys)
2. try Safely Removal In OS.
3. Check Disk for iODD ( for Windows)
4. Rename "_ISO" folder name to other name. create new folder named "_ISO". and copy files to this folder. (not moving)
5. Backup the data of iODD, and Initialize All

If there is hardware problem

1. Reboot the PC
2. Please change USB cable
3. Connect iODD to the port of PC back panel.
4. Try it on another pc
5. Please change the HDD.

Using a Virtual USB Optical Drive (DVD-ROM or Blu-ray ROM)

1. copy ISO files to "_ISO" folder. (or to subfolder)
2. Safely Remove. (Required for NTFS )
3. If Power Saving mode is not active , then Go to Power Saving State
   • If "Plug Out ..." (or "Plug Out ...") message appears, disconnect the iODD.
4. Connect iODD to a PC. and power on the PC.
5. (Optional) select iODD or USB CD-ROM as the first priority of BOOT order in BIOS.
6. If a file has not been selected, then select an ISO file. Selecting a file
7. If PC doesn't find boot device, then reboot the PC. (Ctrl-Alt-Del)

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 VMDK file is supported.
• Create VHD files directly to iODD by "VHD Tool++". ("VHD Tool++" can creates a file without fragment)
• You can create VMDK by changing file extension. (VHD -> VMDK).
• 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).
• If you want to change to DUAL-MODE or to change Write Protection option, rename the VHD filename. refer to "VHD Tool++"
• Max 4 Virtual Drives are supported at the same time ( Successive selection within 3 seconds)

1. create a VHD file using a tool. (VHD Tool++).
2. If successful, safely remove iODD from OS. (#Safely Removal In OS. Very Important to NTFS.)
3. If Power Saving mode is not active, then Go to Power Saving State
   • If "Plug Out ..." (or "Plug Out ...") message appear, disconnect the iODD.
4. Connect iODD to a PC. and power on the PC.
5. (Optional) select iODD or USB Device as the first priority of BOOT order in BIOS.
6. If a file has not been selected, then select a VHD file. (Selecting a file)
7. If PC doesn't find boot device, then reboot the PC. (Ctrl-Alt-Del)

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.

FAQ

Firmware

1. There are 2 sorts of iODD's Firmware.
2. FAT version - supports Fat32 and exFAT partition.
3. NTFS version - supports NTFS partition.
4. There are 2 types of encryption version. one is 6x . the other is 7x.
   • 7x is more secure than 6x against brute force hacking.
   • 6x and 7x are not compatible to each other.
     • If your iODD is encrypted, then before updating iODD to other firmware, you must backup your data.

How to update

Requirements : PC ( Windows OS, USB Port)

Warning - You must connect only one iODD device.

Please update the exact firmware matching the first partition of iODD.

If you update wrong firmware, retry the updater with correct firmware.

1. Download the below firmware file.
2. Uncompress the zip file to proper folder.(Do not run it within zip file)
3. Run the EXE file.
4. If "Device is Detected" message appears, then press "Update" button.
