alpha% sudo fdformat /dev/fd0
Format 1440K floppy `/dev/fd0'? (y/n): y

alpha% sudo dd if=/dev/fd0 of=/tmp/fd0 bs=9216

2 files, 2 used, 605 free (21 frags, 73 blocks, 3.5% fragmentation)

I can't reproduce the failure... :-(

Note that the floppy was already formatted. I need to check with an
unformatted floppy to see if I can *actually* format a floppy. All
I know now is that I didn't mess up the floppy :-)
