I have been using a laptop hard drive in a sabrent 2.5" external enclosure for a few months to move files around from one computer to another. The enclosure came with usb cord which has two usb plugs; one for data, one for power. I have always had trouble pulling enough power even with both jacks plugged in. It sometimes craps out when transfering files. In which case I just unplug, reattach and try again. But yesterday when this happened, I plugged the drive back in, the unit powered up but windows no longer recognizes the drive. I get a message "usb device not recognized." I have also tried the drive in a couple computers running windows 2000. I get a similar error on these machines "unknown usb device." The drive worked on these computers before as well.
The hard disk definately gets power as I can hear it click on and the data light blinks red. Is it dead? or is there something wrong with the enclosure?
