I lost two hard drives on two different computers last week. When I plugged in my Maxtor 3200 to the new hard drive, it would not power up. I tried a different power supply on exactly the same model and it still will not power up. So I cracked open the case and now have the hard drive out. My thought was to put it into an old computer and transfer the files to another external drive BUT I seriously don't know what I am doing! HELP!
