NTFS does not write Immediately the data to HDD.


  • Initialize the drive with (wken:MBR) or (wken:GPT).

    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). (safely remove).
  • Reconnect Iodd.
  • If the screen is not matched what you copyed, Press 4 for 3 seconds.
    You can select the default partition.

If It is hardware problem
  1. Reboot the PC
  2. Change USB cable
  3. Connect to another PC.
  4. Connect to PC with pressing 9 and enter for 7 seconds.
    and will refresh whit the same firmware.

  2. Refer to #Menu
  3. You can configure max 5 device individually.

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

  1. A ODD device is needed. ( Configure Multi Device )
  2. copy ISO files to ioddMini. (root or subfolder)
  3. Safely Remove. (Required for NTFS )
  4. Reconnect.
  5. select the file.
  6. If you want to save loading status, press <colde>9</code>.

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.

    Or You can copy VHD file to ioddMini directly. But the file must be unfragmented.
  • Max 3 VHD Drives are supported at the same time.
  1. create a VHD file using this tool. (VHD Tool++).
  2. Reconnect.
  3. select the file.

  5. Make an image to the VHD drive of ioddMini with image tool.

Using a Virtual USB Floppy Drive (Virtual FDD)

  • Not all computers support this drive.
  • Uncompressed floppy images (IMA, IMG, BIF, VFD) are supported.
  • IMG, BIF, VFD image file extension must be renamed to IMA.
