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.

It fills the drive with random data so that the previous data can not be recovered. Now, that is good if you used that hard drive for sensitive stuff which you don't want anybody to possibly recover. If the hard drive is new (meaning you never used it or used it briefly or you don't care for the data on it as it may contain only 56 gb of cats pictures) and I say new for you referred in your post to a "new computer" then overwriting with random noise is not something you will want to do for the operation takes a loooong time.
As far as the "Now my PC act as if it is full. What did I do wrong?" I don't understand and I have no idea.
Welcome to the libre community!
P.S: also notice that hard drive encryption gives you only physical security, that is security against an attacker that can physically access your PC (as in the case it gets stolen) and it won't make your PC any more secure on the net AFAIK..
Thank you for your answer! And warm welcome. It's only that I cannot download new programs / software, 'cause there's no more space. I don't understand that myself, 'cause I doubt Trisquel is using 500 GB. That's why I thought it had something to do with encryption over-writing free space (?). But like I said: I'm all new to all this.
I understand that I don't need to over-write free space if my computer is new.
I also want to learn about proxy and/or VPN, privacy online. I finally learned about GnuPG, encrypting files and documents, and sending encrypted letters as attachment. It's very cool, and I'm totally in love with GNU, free software and Trisquel, even though it's a challenge to someone not educated within computers. But I think I'm a fast learner.
Great to be here!!
> it's a challenge to someone not educated within computers.
And this, my friends, is the problem with free software adoption today.
It also has to do with the fact that computers are very complex machines.
And also with the fact that most so-called "basic computing" courses
only teach people to use non-free software, or equaly worse but more
limiting in terms of basic knowledge about computers, they only teach
people to use Windows, and still call the course "basic computing".
What is the output of 'df -h' (to be entered in a terminal)?

You have space. Could you precisely explain what your problem is? What do you do? Is there any error message? If so, what is the message?
Sorry for the confusion. I was working in my terminal, and wanted to install some programs. VIPole Secure (which I heard is safe), Emacs and Vim, but the message said I had so and so much MB, but needed more to install. I don't remember the exact message, because a lot were happening in the same time. I'm and amateur, just started out with GNU/Linux, so I need to look more into this. Sorry guys. Thanks for everything!
According to the output of 'df', you have 10 GB left to install packages. You need to install many disk-demanding applications (such as games with a lot of graphics and music) to require that much space. Have you tried again to install the packages (e.g., from the "Synaptic package manager" in the "System settings")?

I'm also a quite unexperienced computer user (I do have some
experience, but not what is need to be called advanced).
As an addendum, if you ever need to remember what has just done, most
(but not all) free software nowadays have long but friendlier options.
The "-h" short option of GNU Df is equal to the "--human-readable" long
option. If you have the "bash-completion" package installed (someone
please correct me if I'm wrong about the package name, or if it's not
needed at all), you just have to write the option until "--hu" and then
press TAB once to get "--human-readable" written for you.
"bash-completion" doesn't work for every command, but it's very helpful.
Also, if you want to, there's alway GNU Info (the "info" command) which
you can use like this:
info df
To see the documentation for the "df" command (GNU Df). Once done,
press Q do quit GNU Info gracefully/gently.
> Now my PC act as if it is full.
What do you mean by this? What are the symptoms of the problem?
Thank you everyone for advises, and a warm welcome. By "acting like it's full", I mean that I cannot download programs, nor new software. I don't know why. I don't think Trisquel is using 500 GB HDD, so I thought it had something to do with encryption of the HDD and/or over-writing the free space. But all this is new to me.

As mr. Bananna Magique said please paste here the output of dh -f
That will tell us your partitioning scheme and how much free and used space is there in each partition.
