might want to give the old school Spin Rite a whirl. I have recovered many a disk with a bad sector 0 error in the past. It takes a while and doesn't work all the time but it might be worth a try.


*EDIT*


Just saw that Nihil mentioned Spinrite in his first post. I would still recommend that you give it a try. It can take a couple of days on a very large drive that is reporting sector 0 bad though. I ran it on a 300gb drive a few weeks back and it took 4 days with deep inspection turned on.

I recovered the drive though
