This reminds me of a problem I have with superformat (fdutils 4.3, freshly
recompiled under kernel 2.0.13).

I've not been able to format anything.

shalott:~# superformat -d /dev/fd0 -s 18
Verifying track 0, head 0 read: I/O error
read: I/O error
remaining -1
Verifying track 0, head 1 read: I/O error
read: I/O error
remaining -1
Verifying track 0, head 0 read: I/O error
read: I/O error
remaining -1

[here I took out the floppy]

Verifying track 0, head 1 read: I/O error
read: I/O error
remaining -1
shalott:~# fdformat /dev/fd0H1440
Double-sided, 80 tracks, 18 sec/track. Total capacity 1440 kB.
