==unmounting a USB disk==
Sometimes a user has cd'ed to a USB disk and then if someone else tries
to unmount the disk they will get this message:
The solution is to find the offending process and kill it cold.
If the disk is labeled '120514a' then the steps are:
  lsof | grep 120514a
you might see something like this
bash      8367      dgs  cwd      DIR      8,49    20480  61341743 /media/120514a/user/cs
you can now kill this process as
  kill -9 8367
and then you can do
  umount /media/120514a
