I use 5 1/4" DD and HD disks.  After I've done some experimenting with
unconventional formats, DOS sometimes can't reformat the disk.  I can
always wipe out the disk and start over if I put it in its sleeve and
rub a strong refrigerator magnet over it.  But the magnet has to touch
the sleeve, and I have to go over it pretty thoroughly.

However, when I've done that, I haven't just corrupted some of the
data, I've low-level unformated it!
