does it have power? can you take drive out of enclosure if not under warranty & try it in your tower?
it has power this happened overnight and it wasnt droped or anything it just stoped working I dont know why but it seems that it doesnt spin when I turn it on I only hear something like bzz bzz bzz and after four of those noises it beeps and than it starts all over I dont have a warrenty so I have to try to six it myself thanks
