    I have two front USB ports in my case. For some stupid reason, only one of them works even though they're both connected to USB connectors in the mother board, but that's not the problem (for now).

    The problem is, I've changed the location of the USB connectors randomly to finally get the faulty one to work (the other one stopped working though). So I turned on the computer, connected my external HDD, and got a message "USB Device Not Recognized" from windows.

    Now every single PC I plug in my HDD to still says the same thing!! I can't see the HDD in windows so I can't format it or do anything! there are tons of important data in there. :(

    Is there anyway to fix my HDD through software? also, do you have any idea what the problem with my front USB port could be?


    your help is much appreciated

    Let's deal with one problem at a time. First off, have you tried the hard disk on one of the rear ports? If it fails there also, let's try this, and DON'T plug it into the front connectors.

    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.

    Thanks John, I really appreciate the effort you've put in your reply. But unfortunately, it still doesn't recognize my USB drive. :(

    any other suggestions?

    Time to take the physical drive out of the USB case and connect it as a secondary drive in a desktop machine. This will isolate it to the USB case or the drive.
