- 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.
