I just bought a 3.5" ata external hard drive enclosure for an old hdd but I is not recognized by the pc/laptop. I am using windows 7 on both of them. I already checked under disc management in settings for the drive letter but it doesn't show up at all. I also tried all different jumper settings possible on the hdd but had no luck. I tried it under windows vista as well with same results. By the way the hdd spins up just fine and there is a green led showing its jut fine but window doesn't recognize it at all. I even changed the usb cable with a different one but that also didn't help. Any idea how I can get it to work? Thanx in advance.
