[Trisquel-users] Security

[srwangberg]

Hi guys! I'm new to GNU/Linux, Trisquel. I tried out Trisquel on my old PC,  
and was asked if I wanted to over-write free space when encrypting my HDD.  
Now my PC act as if it is full. What did I do wrong? So when I'm encrypting  
my HDD on my new computer, should I over-write free space or not?

Also. If there's anyone in Mid Norway into Trisquel, free software,  
encryption and Emacs, please let me know.
