Selecting a File

To ensure the loading state is maintained after a file is selected, you must save the state manually.

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.

Initialization

  • Initialize the drive using (wken:MBR) or (wken:GPT) 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 4 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:
  1. 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'.
  2. Temporary Reset: Press and hold 7 while connecting to the PC.
  3. Factory Reset: Press and hold 1 while connecting to the PC.
  4. Disk Check: Run a Disk Check ( chkdsk) on Windows to repair file system errors.
  5. Re-initialization: Back up your data and perform the Initialization process again.
If the issue appears to be hardware-related:
  1. Reboot your PC.
  2. Try a different USB cable.
  3. Connect the device to a different PC.
  4. Force Firmware Recovery: Connect the device to the PC while holding both 9 and ⏎ for 7 seconds.
    This will re-flash the current firmware to recover the device.

Configure Multi Device

  1. Go to Menu -> Mode Setting.
  2. Refer to the Menu section for detailed navigation.
  3. You can configure up to 5 devices independently.

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

  1. An ODD device must be enabled. (See Configure Multi Device)
  2. Copy your ISO files to the IODD (root or subfolders).
  3. Use Safely Remove Hardware. (This is mandatory for NTFS partitions).
  4. Reconnect the device.
  5. Select the desired ISO file.
  6. To save the loading status for future use, press 9.
  7. If the PC does not detect the boot device, reboot the PC using (Ctrl-Alt-Del).

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)
  • Important: Only fixed-size VHD files are supported. (Dynamic VHD and VHDX formats are not supported).
  • Fixed-size VMDK files are also supported.
  • It is highly recommended to create VHD files directly on the IODD using "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.
  1. Create a VHD file using VHD Tool++.
  2. Reconnect the device.
  3. Select the VHD file from the list.
  4. To save the loading status, press 9.
  5. 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.
