I had the same problem. I got no resopnce, so I went about it *MY* way. It
may not be the best, but it works.
I had three bad sectors.
1) File the hard disk with files of 10Meg, marking the files that cover bad
sectors.
2) Delete one of the files that has bad sectors.
3) file the hard disk with files 1/10 the size of the previous file.
4) repeat steps 2 and 3 until you have sufficently small files.
NOTE: I did this from a directory called HARDERRORS, and named the files by
the sector number that was bad in it, and removed rw permissions
from all three files AND the directory. I know this doesn't stop root
accidently removing them, but who logs in as root all the time anyway?
I think I got each of my bad sector files down to 512 bytes. It took some
time to do (4 hours I think), but saved frustration later.
If someone has a better idea PLEASE let me know.
