Put a 1440KB (the standard one) floppy in your drive.
Do a fdformat /dev/fd0u1680 and then a mkdosfs on it.
It will work well with normal mount, but not on supermount.
On supermount, with these floppies, when you take the
floppy out to unmount it, and put it back again, you
find the files in it totally corrupted!
