    Hi,

    I have a Compaq V4310NR with XP Home. Recently, it stopped reading any removable drive such as USB Flash or via the 9-in-1 card reader for SD cards. Once inserted, the drive is shown, but when you double-click it says "disk in drive d is not formatted would u like to format it now?"

    And the thing is that these are perfectly fine in other computers. I've tested repeatedly with USB and SD card. Also, if the card is in camera which is then attached via USB, it can usually see the data (not tested in all configs).

    Is this work of some virus, or some settings gone bad? Please help, and thanks in advance...

    First step, Start, Programs, Accessories, System Tools, System Restore. Create a restore point and name it something like "Before USB Fix". This is to bail you out if something goes wrong during the following process and makes things worse.

    Create a file with NOTEPAD containing the following lines and save it as FIX.REG

    -------------------------- Use text after this line --------------------------------
    REGEDIT4
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment]"DEVMGR_SHOW_NONPRESENT_DEVICES"="1"

    -------------------------- Use text before this line --------------------------------

    Double click on FIX.REG and say yes to the Merge Into Registry question.

    Unplug ALL USB devices.
    Open Device Manager.
    View, Show Hidden Devices.
    Uninstall all devices under USB Controllers.
    Uninstall all devices under Disk Drives that you know are not present.
    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.
    If you have a yellow ? with unknown devices, uninstall all of the entries there as well.

    When this is done, reboot TWICE.

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

    NOTE: If you have a USB keyboard and/or mouse, you'll have to modify the instructions and leave enough parts for those to function. I don't have one yet, so I haven't had time to modify the instructions.

    I'll give it a try soon. Any background as to what's happened here? Did the Device Manager get confused as to what to show as present? But it only shows the drive when I plug it in, and removes it when removed physically.

    Again, thanks for the help...

    USB settings get scrambled at times when using multiple mass storage devices. I've had to use this reset a number of times.
