- 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!
