Mounting/unmounting TrueCrypt volumes without opening the program

  • 772

I used the advice given at the end of this article to mount a TrueCrypt volume by double-clicking it. But I can't unmount it without opening TrueCrypt (umount: /media/truecrypt1 is not in the fstab (and you are not root)) so being able to mount it without opening the program is kind of a moot achievement. Any suggestions?

    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

  2. try adding it to the /etc/fstab. That worked for me.

    /dev/mapper/truecrypt1 /media/truecrypt1  auto   rw,user 0      0

  3. If you're having unmount issues with TrueCrypt, try going to Settings > Preferences > System Integration and check 'Do not use kernel cryptographic services'.

  4. Stop using your volume and make sure no other program's current working directory is on the volume. Then try:

    umount -a

    This will try to unmount all unused filesystems on your computer, including your TrueCrypt volume.
