== How to use ==
;At first please refer to the below [[#Manual|Manual]].
=== Initialize ===
* Two sorts of the firmware are [[msen:NTFS|NTFS]] version and [[msen:FAT32|FAT32]]/[[wken:exFAT|exFAT]] version.
* NTFS firmware version is shipped.
* If you want [[msen:FAT32|FAT32]] or [[wken:exFAT|exFAT]] [[msen:Partition|Partition]], download and update the NTFS Firmware Updater.
* Follow the next steps
# Assemble the HDD or SSD with iODD
# Connect the iODD to PC
# Initialize the drive with [[wken:MBR|MBR]]
# Format the first partition with NTFS. (if the firmware is FAT then format with FAT32 or exFAT)
#* At FAT32 there is 4G byte file size limitation. please expert may use FAT32.
# Make ''_ISO'' folder in root folder. (not sensitive)
# Create or Copy ''*.ISO *.VHD *.RMD *.IMA'' or sub folder tree to ''_ISO'' folder
# Do [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer safely remove] the iODD in OS. ( Very Important to NTFS)
# If Power Down mode is active then release and reconnect the USB cable.
#* If not then press down the jog button in 3 seconds. and Power Down mode will be on.
#* and if ''Plug Out ...'' message is out, release and reconnect the USB cable.
# you will see Sequentially ''iodd 2531'' and a file name in root folder.
;If it is not like the above, follow the next
# Release the USB cable.
# Replace the HDD from iODD.
# Initialize the HDD with [[msen:GPT|GPT]]
# Go to [[#Initialize]](1, the first step) and retry (MBR -> GPT -> MBR).

=== Using Virtual USB Optical Drive (DVD-ROM or Blu-ray ROM) ===
# Copy your ISO files to ''_ISO'' folder or sub folder.
# Do [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer Safely Remove] in your OS. ('''necessary''' in NTFS )
# If Power Down mode is not active then press down the jog button in 3 seconds. and Power Down mode will be on.
#* If ''Plug Out ...'' message is out, release the iODD.
# Connect iODD to your PC and power on the PC.
# (Optional) Make iODD or USB CD-ROM the first in the priority of BOOT sequence in BIOS.
# (Not required if an ISO has been selected) Select an ISO file by Jog dial.
#* If Firmware version is 1558 or higher then loading status is automatically saves. if not, you must save it manually by pressing down jog dial in 3 Seconds
# If PC will not find booting device (iODD) then Press ''Ctrl-Alt-Del'' to reboot.
==== Troubleshooting ====
* Confirm the ISO file whether it is bootable.
* If your PC is old or does not provide multi LUN, please select ''CD-MODE'' in Menu.
* In order to confirm whether the ISO file is not good for booting, try to test it with the validated PC.
* Although it is bootable ISO file, it may not boot with USB DVD-ROM. test if it is same result with USB DVD-ROM.
* If It can boot in USB DVD-ROM and can not boot in iODD, please use USB Y-CABLE for adding external power.
* If your laptop has own internal DVD-ROM and iODD does not boot, please disable internal DVD-ROM at booting device list on BIOS settings or remove it.

=== Using Virtual USB fixed disk drive (Virtual Hard Disk) ===
* Only fixed VHD file is supported. (Not dynamic VHD nor VHDx files)
* Make VHD files directly by [[VHD Tool++]]. (VHD Tool++ can make a file without fragment)
* Press Jog dial to select VHD file and iODD will be rebooted with ''CD-MODE'' and is recognized as USB disk drive (Virtually). 
* If you want ''DUAL-MODE'' or to change ''Write Protect'' option, rename the VHD file. Refer to [[VHD Tool++]]
* Can select max 4 Virtual Drive at the same time ( Successive selection within 3 seconds)
# Create a VHD file with using [[VHD Tool++]] at ''_ISO'' folder
# If successful, Do [http://windows.microsoft.com/en-US/windows7/Safely-remove-devices-from-your-computer safely remove] the iODD in OS. ( Very Important to NTFS)
# If Power Down mode is not active then press down the jog button in 3 seconds. and Power Down mode will be on.
#* If ''Plug Out ...'' message is out, release the iODD.
# Connect iODD to your PC and power on the PC.
# (Optional) Make iODD or USB CD-ROM the first in the priority of BOOT sequence in BIOS.
# (Not required if a VHD has been selected) Select a VHD file by Jog dial.
#* If Firmware version is 1558 or higher then loading status is automatically saves. if not, you must save it manually by pressing down jog dial in 3 Seconds
# If PC will not find booting device (iODD) then Press ''Ctrl-Alt-Del'' to reboot.

=== Using Virtual USB Removable Flash Drive (Virtual USB Flash Drive) ===
* Almost the same as the above method (Using VHD) only if the file name extension is modified by ''RMD''.

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