[nflug] >mount

[Robert Meyer]

If there is a process that is currently in the directory that the drive is
mounted under, it cannot be unmounted.  You can use the 'fuser' program with
the -m <block device> option to find out what has the file system mounted.  You
can probably use the -k option to kill the processes that have it open and then
do the unmount.

Of course, this is a really rude thing to do to users :-)

Have you considered using the 'supermount' system?  It will mount file systems
when you attempt to access them and unmount them when nothing is talking to the
file system any more.  Kinda cool for CDROM and floppy drives.

Cheers!
