The hard drive in the wife's laptop up and died on us tonight. Just like that. It was working fine a few hours ago and then I put it in hibernate mode. She went to turn it back on and got nothing but a BSOD. The drive was making those characteristic clicking and whirring sounds of a dead hard drive, so it sounds like it's time for a new one. Sadly, the last back up was from a few months ago just before Christmas, so there's going to be some data loss.
Laptop drives are surprisingly cheap. Over at Newegg a 160GB drive can be had for $120. Surprising just how small these things are.
