formatufd.exe or ufdprep.exe



    In the course of trying to get a USB device to boot directly for XP Embedded,

    I ran UFDPREP.EXE on one of my USB devices.

    Formatting the drive doesn't change it. And now BOOTPREP won't change it's MBR.

    How do I undo what the UFDPREP utility has done to the USB thumb drive?

    (Turns out my motherboard is modern enough to see USB devices as a hard drive...

    but it took me a while to figure that out.)

  • Hi Rick,

    Why do you need to run BOOTPREP on the UFD?

  • Hi Cuongp,

    Before running UFDPREP on it, my motherboard BIOS would show the USB drive in the enumerated list of hard drives that could be booted from.

    Since running UFDPREP on the USB drive,

    the USB drive no longer appears in that list.

    And I'd like to undo what UFDPREP has done to the little USB drive rather than throw it away and buy a new one.

  • Hi Rick,

    What kind of BIOS is on that system and is the BIOS set to enable USB HDD emulation?  And what kind of UFD do you have?
