I've got a 2TB external HD just for personal use, with an 8GB primary FAT32 partition (I made it there from the beginning just in case I wanted to install Ubuntu at a later moment)
Now I could probably figure out how to set it up using a Live CD, but unfortunately my DVD drive broke last week, and ATM I don't have access to a USB flash drive (I might tomorrow, but it's kinda time-bound)
Yep, I am pretty much a Ubuntu newbie.
