   Copy your files off, and try formatting it. If it gives the
slightest hint of trouble, dump it in the trash.

   5.25" disk repair is a tricky business at best, and if you don't
have any experience with it, my only advice is to seek out someone
with a heck of a lot more experience in the field. Even then, if
something spazzed and wrote all over the track, your data is
essentially gone. [NSA and FBI labs apparently have equipment that can
read what was previously written to disk before it was written over,
but that equipment costs megabucks, and is used mainly in criminal
investigations.]

   Do I need to insert yet another Public Service Announcement here
about how useful backups are?
