    i'm running win xp and made the stupid mistake of plugging in two usb flash drives. now one of them cannot be accessed at all but it works if i plug it into another computer so i know it isn't a problem with the flash drive iteself.

    when i plug it in, windows takes a few minutes to detect it, slowing down the entire system. in My Computer, when i try to access it, the system slows down some more then an error message saying that an I/O error occurred.

    i believe i need to uninstall the device somehow but every time i try to do that in Device Manager, the computer locks up and i end up having to reboot.

    what should i do?

    (another thing about this flash drive...it's one of those that is partitioned into a 1.44mb floppy drive and the rest as the "removable disk". i know that my computer has some sort of issue with floppy drives since it doesn't have one built in. so i use an external FDD and when i try to safely remove it i get a blue screen of death and reboot. before i had the above problem with the flash drive, i'd also get the b.s.o.d. when safely removing it. but that's another issue altogether)

    Unplug ALL USB devices.
    Open Device Manager.
    View, Show Hidden Devices.
    Uninstall all devices under USB Controllers.
    Uninstall all devices under Storage Volumes. Say no to any reboot prompts until you are finished. Also, if a Storage Volume doesn't uninstall, ignore it and move to the next one.

    When this is done, reboot TWICE.

    Reconnect the USB devices and see if they're recognized properly.

    Please help.
    I have a similar problem with an LG 256 MB Flash drive running under Windows 98 SE (pl don't advise an upgrade.. this is my office networked computer. I will have more other hassles by upgrading :( ).

    I have removed and reinstalled the USB port drives and I can see no problems with them.

    I have reinstalled the LG Win 98 USB drivers more than 3X.

    The USB drives did work very well until a few days ago.

    The USB works fine on my home computer running Win 2K

    Thanks :confused:
