Suggestion One

You can use a terminal to unmount it.

For example, I have an encrypted file named enc1 that is on /home/desgua/Dropbox/, so to mount it I should use:

truecrypt --mount /home/desgua/Dropbox/enc1 /mnt/mymountpoint/

And to unmount:

truecrypt -d /home/desgua/Dropbox/enc1

or simple:

truecrypt -d (which should unmount every truecrypted mounted files)

.

Suggestion Two

Also you can create a launcher to unmount it:

1) Paste this at terminal: gedit ~/Desktop/unmounttruecrypt.desktop,

2) Then paste this into the file and save:

[Desktop Entry]

Type=Application

Encoding=UTF-8

Name=Unmount Truecrypt

Comment=Unmount all mounted Truecrypt files

Exec=gnome-terminal -e "bash -c "truecrypt -d ; exit; exec bash""

Icon=/usr/share/icons/Humanity/actions/48/player_eject.svg

Categories=Application;Accessories;

3) Now look at your desktop and drag the file to the Launcher.

.

Suggestion Three

Make a script to unmount it for you:

1) Paste this at terminal: gedit ~/Desktop/utscript,

2) Then paste this into the file and save:

#!/bin/bash

mnt=$(mountpoint /mnt/mymountpoint/) # See suggestion One



if [[ $mnt == "/mnt/mymountpoint/ is a mountpoint" ]]; then



    truecrypt -d /home/desgua/Dropbox/enc1 | zenity --progress --percentage=40 --auto-close --title="Unmounting" --text="I am umounting it now."

    sleep 2 | zenity --progress --percentage=100 --auto-close --title="Done!" --text="Done unmounting!" 

    else



    sleep 2 | zenity --progress --percentage=100 --auto-close --title="Already done!" --text="It is unmounted already!" 



    fi



exit 0  

4) Paste this at terminal: chmod +x ~/Desktop/utscript
