Fresh Install On 320G HD; Only 238G Home Folder

[Bryce Hardy]

Greetings, I have fresh installed F15 onto my laptop that has only one
disk drive of 320G and no other OS. I checked the "Use All Space" box
in the installer but otherwise left everything at the defaults. I was
surprised to see the Nautlilus status bar telling me there was only
31G of free space, when I know that my Music is only about 55G and
Videos only about 120G. Following are the outputs from the commands
that can think of to see what's going on, but I'm stumped:

The only obvious red light is the message about various disks not
containing valid partition tables, but I don't know what that means. I
had this while running the beta, but was hoping it was a glitch that
would be solved with a fresh intall of the final, but it's still
happening. Any pointers or advice would be much appreciated, and sorry
for the long post.
