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

assemble the HDD or SSD with iODD
connect the iODD to PC
initialize the drive to MBR. (wken:MBR)
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). (safely remove).
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.
The following messages will appear sequentially in LCD
- "iodd 253(4)1"
- a file name

Initialize All

If Initialization fails, follow the next steps

disconnect the USB cable.

Initialize it to GPT. (msen:GPT)
redo Initialization (from the first step). (your HDD is initialized as MBR -> GPT -> MBR).
Open back cover
Press tact switch
Connect USB cable
Wait 7 seconds
Release tact switch
Wait 1 minutes
All done

First Aid

(2531). press the Jog Dial and hold. and then connect iODD to PC. (#2531 Keys. refer to Startup Keys)
try Safely Removal In OS.
Check Disk for iODD ( for Windows)
Rename "_ISO" folder name to other name. create new folder named "_ISO". and copy files to this folder. (not moving)
Update it with the latest firmware.
Backup the data of iODD, and 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)
Safely Remove. (Required for NTFS )
If Power Saving mode is not active , then Go to Power Saving State
- If "Plug Out ..." (or "Plug Out ...") message appears, disconnect the iODD.
Connect iODD to a PC. and power on the PC.

If a file has not been selected, then select an ISO file. Selecting a file
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)

create a VHD file using a tool. (VHD Tool++).
