Resurrecting corrupted floppies
Here's how to make a floppy disk with "track-0 bad" reusable again:

If the track zero of a floppy disk is found to be bad, no DOS or Windows utility is going to do anything about it--you just have to throw it in your unrecycle bin.

This tip cannot recover the data, but can make the disk carry things again, at least for the time being (moments of desperation).

How to:

(A) Format the disk with Linux. Build a Linux file system (don't use mformat). I did this some time before by invoking the makebootdisk command (in Slakware) and stopped after the formatting was over. There should be better ways to do it in RedHat 5.2 or other recent versions.

( Reformat the disk with Windows. Use the DOS window and the /u option while formatting.
