As far as I know, MS-DOS was just reading through all the sectors to see that they are okay. Of course hard disk reformatting is not something you do everyday, so one should be able to stand a little delay there rather than finding bad sectors later on. Some OEM's MS-DOS (don't remember who) actually *writes* to every sector. This also destroys whatever is there. Baring that, a high-level format is usually recoverable with the right software. yawei
