I've been happily using Ubuntu on an 8GB Lenovo laptop for a couple of months now. I initially wiped Windows off the 750GB hard drive and installed 12.04, then upgraded to 12.10. Now I'm planning to do a fresh install of 12.10 from scratch so I can encrypt the hard drive.
My question is, how can I look at my current partition information to see how space is actually being used? I stumbled on a program a month or so ago that gave me a nice listing of my current partition scheme and how much space was actually being used in each partition. I'm sure it wasn't gparted, but I can't remember what the program was, though, and I'd like to rejigger my partition scheme a little when I do the fresh install. Can anyone help me out?
