Hello,
I've got a semi-old simpletech 160 gig hard drive and I lost the power supply for it. I had an AC cord laying around that fit it and plugged it it. The laptop it was hooked up to by USB instantly shut down and the light on the hard drive shut off. I immediately unplugged the whole deal. Did I fry this thing? I think the hard drive is 5+ and the block is 12+ but nothing is labeled.
