    are they host powered devices? if so you might have to patch in both cables that are on it into the usb slots as it might not be getting enough power

    Many recent, and especially 2.5" EXTERNAL DRIVES, COME WITH A 'y' CABLE (scuse caps lock there !) that needs 2 USB connections to get enough power. Each USB socket is limited to supplying 500mA [IIRC]

    download the latest window 7 updates

    after doing this and if you still have problems, go to control panel, troubleshooting, hit hardware and devices and see what it brings up

    if this doesnt do anything try useing the usb slots at the back of your pc
