Hmm, that seems odd. Have you tried other ports on the laptop? Or is it a Sata connection? Guessing it's a usb connection though yes i have tried all 3 usb ports on the laptop... yes it is a usb connection (external 2.5" hdd) Hmm, guess I'm not much help on this then, lol Have to wait for a guy that's good with hardware to respond. Only thing I can think of is googling it, but you've probably done this with not much luck
