even having one terminal open w/ it being in the directory of your cdrom 
drive will cause your cdrom (or anything else) to not unmount.

A good way to find out what program has your cdrom open is to type:

lsof|grep name

i.e.:

myrond@hexagon:~$ lsof |grep /home/myrond
bash    19455 myrond  cwd    DIR    3,2    2072          2 /home/myrond
lsof    19498 myrond  cwd    DIR    3,2    2072          2 /home/myrond
grep    19499 myrond  cwd    DIR    3,2    2072          2 /home/myrond
lsof    19500 myrond  cwd    DIR    3,2    2072          2 /home/myrond

The fields are laid out as follows:

COMMAND   PID   USER   FD   TYPE DEVICE    SIZE       NODE NAME

The only way (that I know of) to umount a device is to be absolutely sure
NOTHING has the device open! :)
