    Hi

    A 3.5" external hard drive connected to my Windows XP machine via USB 2.0 has a "disappearing" and "reappearing" partition problem.

    After the external drive is turned on, all four partitions on it will be displayed. Very soon, they will all disappear in Windows Explorer. After a brief moment, they will reappear along with a USB-symbol icon in the taskbar, which brings up a "Hi-speed USB Device Attached to non-Hi-speed Hub" warning suggesting that I use free Hi-speed USB ports (indicated in bold).

    My computer's USB ports are all USB 2.0 and I've tried attaching the external drive to different ports on the machine, all with the same result.

    Would anyone hazard a guess as to the likely cause of this problem:
    (1) Failed (or failing) USB controller on the external enclosure?
    (2) Failing power supply to the xeternal enclosure?
    (3) Corrupted partition table on the drive?
    (4) Failed (or failing) USB controller on the mobo?
    (5) Any other cause?

    The enclosure also has an eSATA port. When connected via eSATA (or USB 2.0) to another computer, no such problem appears.

    Thanks in advance!
