First of all I am a brand-newbie to linux/ubuntu. Second, I have searched on my own for a way to do this for 4 hours and just can't quite find it or find it explained the right way. I apologize if this is a duplicate or a difficulty 1/100 for any basic linux/ubuntu user.
That being said, here is my setup: I am running Xubuntu 12.04 alongside ChromeOS via "crouton" on an Acer c7 Chromebook. It's a fresh install from yesterday (the xubuntu that is). I've managed to figure out the launcher, and the apt-get and ppa repository and that stuff... for the most part. I got a few basic programs - FireFox, Skype, VLC, Audacious, and qBittorrent. So now I'm ready to download some videos and music and I arrived at my problem.
The problem is I am (very) quickly running out of space (660 MB remaining). Thing is it's a 320 GB HDD and I have a 311 GB drive sitting greyed out on my desktop. When I try right-clicking and mounting, I get this:
So I went in sudo fdisk -l and it promptly told me that /dev/sda was a GPT and fdisk could not format it, and I needed to get GNU Parted. So I tried simply "sudo apt-get install parted" and sure enough it grabbed GNU Parted 2.3. Here is what (parted) print returned for me:
So my question is how can I get this 311 GB of space working for me as storage? To be clear it's just a partition on my internal 320 GB HDD that came with my Acer c7 chromebook. Do I need to mount it somehow or could I somehow change one of the other existing partitions to just be bigger?
Again I apologize for my level of noviceness and any help is much appreciated!
