Thanks, I'll check them out.
Ooooooh yes, his drive is most definitely done for. It was funny and sad at the same time. We were video chatting, and he had one of the mounting things that came with his iSight in his hand (it was the piece that has a magnet built into the bottom of it). Suddenly I hear him say "Wow, my computer makes a weird noise when I put this thing on it...it has a magnet in it". At that point, it was too late to do anything but explain that a hard drive is a magnetic storage medium and that at the very least he'd probably erased his data and at the worst, he might have damaged his hard drive. Sure enough, he tried to open up an application and it wouldn't open (apparently there was enough of the OS and iChat in RAM at that moment to keep things running, but the damage was preventing any new apps. from opening). He went to the Apple store and they quoted him a price of over $400 to install a new drive (they said it was physically damaged). What a bummer! And such a simple thing, and a situation that most non-technical people could easily end up in.
[Wow! I just checked that link. What a great price for a really nice drive. Thank you!!]
