as I said, put the hard drive(s) in a working pc, and use a format to fill all the platters with zero. As for having it fry, yeah the drives may seem like they work for a little while, but they'll really be dying a very slow and painful death. We recently had a pc die cause of a shitty surge suppressor my boss was using, and we lost the power supply on the copier (due to a brown out), so we've got a few tripp lite line conditioners.... good stuff.
