I've hosed a few floppy disks with it, but no drives. What I have seen
happen, however, is that using the 1.72Kb format works until a drive 
starts to age and lose its alignment, at which point, a disk formatted
to 1.72 in *that* drive is not always readable in another drive, and
vice versa. The superformat man page explains this in more detail.

Hmm. I'm not sure how that would happen.

Have you tried reformatting to the standard 1.44Kb using /dev/fd0h1440?
