I've got a simpletech 2tb hard drive which I've used for time machine, but all of a sudden it won't read when I plug it in. I can hear it power on when I plug it in but it won't show up. I've tried plugging in other devices to make sure the ports are still good and tried restarting with and without the hard drive plugged in. I've only had this hard drive a week and haven't done any improper device removals to it. Just wondering if there is a fix or if I gotta take it back. Thanks Also, I am running snow leopard with all the updates.
