I got it working again. This is the magic program that fixed it.

A couple of clicks and a few seconds later, my harddrive was working like nothing happened. Nothing seems to be missing, everything is peachy. Definitely check it out and keep the demo version safe, just in case your harddrive conks out.

I like this program so much, I think I'll pay for it...next time...
