Someone I know has a Western Digital 320GB MyBook that has recently died. It uses a power plug to power the drive and a USB 2.0 to connect to the PC. I plugged in the cord and the little light on the adapter turned on. I plugged the cord into the MyBook and the front LED's came on. When I plug in the USB cord, the computer doesn't see it. It's not in My Computer, or the device manager. I've tried another USB cord too. I'm going to try to take apart the drive and plug it in internally into a PC case next. Can you think of any other options?
