I would agree, if the mount didn't work. But that's what I
tried to point out.

As it is now, the trouble arises from the fact that you actually
CAN read/write mount a read/only-floppy. No complaints from the
mount command.

However, you can't umount it anymore! So you're stuck and it
is mounted for-ever! Unless, you take the floppy out, change it
to read/write, put it back in the drive and do the umount again.

Why does mount not check the read/write of the floppy?
And if it doesn't, for some reason, why then all of a sudden
umount does check for the read/write thing?

Rob.
