More Hard Drive Issues

I wouldn't try any "rescue missions", just get yourself another harddrive.

Bad sectors are deallocated by the harddrive logic itself, so you seem to have a lot more problems than just "bad sectors".

EDIT: To be more precise. Every drive has a pool of spare sectors that replace sectors that become "nearly" unreadable. The hardware logic can detect when a sector is in process of becoming bad. It then copies then data from the dying sector the the spare one, disables the old one, and then links the now filled spare sector to the adress of the old one. This is completly transparent for anything outside the harddrive. You don't have any influence about this.
The only thing that you can do is query if that kind of action happened in the past. That's what SMART is for, it also supplies a log of actions taken by the harddrive. It collects information about various things, etc.

So this means your drive has already depleted all spare sectors (IF the problem is really bad sectors, maybe also the servo is bad, or another issue - there are a bunch of them). So you see that sectors are dying in your drive. And most likely this process won't simply stop. And you're left with no spare sectors..... The next time a sector dies, the data is gone, it's not duplicated anywhere.

So get a new drive fast.

How ya doing, buddy?
