    My USB 2 backup is an issue on my PC but not others?

    My desktop PC (win7) doesn't recognize my Seagate 500 gg USB drive, tried re-booting no help. It works fine on my wife (win7) PC and on my lappie with Vista.

    Upgraded to SSD (from SATA) a few months ago and it was perfect clone and haven't ever had any issues -- if that's any help !

    help

    A damaged USB port is a possibility. Does the PC have another you can try ?

    Do other USB devices work?
    Is the disk USB3 and your PC only USB2? Try a USB3 card.

    cheers, Paul

    Sometimes 'Device Manager' entries can become invalid, especially for USB devices if the 'Safely Remove Hardware' function is not used.

    Disconnect the problem USB HDD.

    Run the following commands in an elevated command prompt (Start/All Programs/Accessories/System Tools, right-click "Command Prompt" then click "Run as Administrator"):

    SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
    (enter)

    START DEVMGMT.MSC
    (enter)

    A "Device Manager" window will open, click "Show Hidden Devices" in the View menu.

    You can now uninstall any invalid/disconnected devices especially any USB devices you suspect might be to do with the problem USB HDD (right-click on the device then left-click 'Uninstall').

    Once you have finished uninstalling devices restart the computer; Windows should re-install any devices as necessary (but might prompt for driver software).

    Once Windows has fully restarted re-connect the USB HDD; hopefully Windows will install any needed drivers (but it might take a few minutes).

    WARNING: exercise caution, particularly with removal of sound, network, and non-plug'n'play devices; devices in these categories might be shown dimmed as if not present but are nevertheless needed for the parent device to function correctly.

    Check Device Manager to see if your USB ports or hubs are working properly. Are they present? Are they red or yellow flagged?

    Do the ports work with any other devices?
