My computer does not recognize my WD1200B015-RNN external drive when I plug it in to the usb port. Any idea what's happened? I now have windows 7. It previously worked on Vista
does windows give you the usb beep when you plug the drive in?? if not try first by updating the mb xhipset frivers and the usb drivers..could have a damaged usb driver. then look at usb cable see if it bent or broken...and check to see if you csn feel the drive spin up. if the drive spins up see if windows disk manament can see if. if not try using the newer wd disk tools to see if it sees it. if it does not it could be the board in the portal drive went bad or the drive itself...if you need the data i would then open the storage device and plug the drive into your mb or use a usb to ide cable.
