    I've done this many times before, and I think it's just a failing drive, but I wanted to check and see if anyone had successfully worked around this problem before. I have a 16GB Transcend flash drive, and it stopped working last week. When I connect it to a computer, I get the message that I have inserted a disk that cannot be recognized. Disk Utility only recognizes the device, but no volumes (see attachment #2). When I try to format it, I get an error that says it Can't allocate memory (see attachment #1).

    Anyone recognize this? I can send it back and get the drive replaced under warranty, just wanted to see if there were any other thoughts.

    Sounds like a failing drive to me, yeah. You could try formatting with another computer...

    the soluce for posix problem !



    Just have to reformat your hard drive with XP first (perharps again...) NTFS
    then plug on your Mac WITH an FireWire, not USB
    Open DiskUtility and re-format in HFS.

    The problem with me come from a try of Paragon* application on my Mac, for instant access in read write delete on an external hard drive (coming from @#! XP user)

    (*)a good good one but creating sometimes a message like read above forum when you want to use Disk Utilities to format.

    After done, unmount your hard drive if you want to use USB connection or let Firewire in place.
