There is lowlevel IDE drive formatting software available from the
drive manufacturers. This may offer some hope.
That said, my experience with fixing ide drives has not been good.
As I understand it, the on-drive controller "spares" out some
tracks and automatically uses them when it finds a (potentially)
bad block. By the time you have visible bad blocks, your drive is
in a bad way. You should (quickly) retrieve any data you need, and
throw the drive away.
With fairly fast 10Gig drives available for a cost less than $200,
I don't think it is economical to spend much time with that drive.
