====== Useful truecrypt commands ======
Opening a truecrypt volume that doen't have yet a filesystem
<code>
truecrypt --filesystem=none /dev/sdg
</code>
The truecrypt volume is then opened in /dev/mapper/truecrypt1

Once the volume is opened it is possible to format it:
<code>
sudo mkfs.ntfs /dev/mapper/truecrypt1
</code>
