I have a Western Digital Password external HD USB2.0
I works on some computer (a desktop PC with Vista, a laptop with XP) and do not works on some other.
I makes an iterative "tick" noise and sometime even makes a beep sound! (it is not even shown on the Windows the device manager)
(I tested it with Hiren Boot CD also : it is the same issue...)
What can I do to make it regonized on all computers? Does it come from the PC usb controller ?
