TrueCrypt - how to "Dismount" even if device is in use ?

[credobyte]

a filesystem code doesn't speak "documents and similar stuff". it speaks filesystem integrity for one thing, and, as every other code in kernel space, keeping a running system stable. if you really want to remove it, remove it physically by hand, but don't expect the kernel to do destructive things or even enabling you to do it thru its code

Oh, yeah .. physically removing my HDD would take at least 10 minutes ( instead of 10-30 seconds from my Terminal window )
Anyway, thanks a lot to everyone - problem solved !

„Problem solved!”, yet no solution named.

Similar problem: can't unmount a darn volume, even though there is no way something really uses it.

fuser -m /home/abd/abd
outputs:
/home/abd/abd: 23468c
And 23058 is just the xterm I use to input fuser command, which is confirmed by lsof:
abd@ubayd:~$ lsof /home/abd/abd/
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
konsole 23468 abd cwd DIR 251,2 4096 2 /home/abd/abd

This drives me mad. I want this unmounted, and readily unmounted any time I need it unmounted in the future, ANY time. How can I achieve that, if even --force doesn't work?

In my case the problem was caused by KDE, which locked the directory the truecrypt volume was mounted into (/home/ab/abd/), because the directory was set in KDE settings as "Documents folder". As soon as I changed the Document folder to somewhere else the truecrypt volume could be unmounted.
