less likely on a windoze world for screwups but it does occasionally
happen if you pop the fd while the light is still green

and even worst in linux/network world ... since an improperly removed
floppy  can tie up your network w/ NFS timeouts ... ls starts to fail, 
nfs login starts to fail... 
	- no way around the "ejected floppy" while its mounted

- from a data standpoint...
  if one is copying data from hd to an automounted fd... its not
  a big deal that the user hit the eject button at the wrong time
  before the system flushed its data to the fd ...

- no script can protect against the user from hitting the eject button
  before data is actually written to the fd  and not just sitting
  in the "floppy cache"
	- umount the floppy... and do "ls -la /mnt/floppy"
	and sometimes you get data thats still in cache

- dont let users mount a floppy --- problem solved.. guaranteed ...
	- what's the point of the floppy ???
