Have your users use mtools instead of mounting the floppy drive.
http://mtools.linux.lu/
Presumably your /etc/fstab has '/floppy' with the option 'user'?
If you take that off, then users can't mount the floppy drive.
Presumably your users are in the group ('floppy' on my system) which is
allowed write access to the floppy device ('/dev/fd0' on my system) ?
Leave them on there, and then they can use mtools.
