Missing Free Space

Hey,

I have a 2008 MBP 15" with a 320gb HDD. Recently, my HDD was full (15gb left) and I assumed that it was simply games, movies etc.
But when I finally sat down and went through it, all I find is that I get up to 200gb storage and have no clue where that final 120gb is.
When I click on Macintosh HD, the files are:
Users - 169gb
Applications - 11.5gb
Library - 7gb
System - 5gb

My question is, where else can I have data stored? I have tried OmniDiskSweeper and that only stops at 170.9gb...

Cheers

 

Solved it, I had to reboot onto Snow Leopard using the DVD and then repair the hard drive - there was an 'invalid file count'.
Thanks

 

Insert your Snow Leopard DVD and restart. When the computer is turning on, hold 'C' and it should soon be booted from the DVD. There will be a window in the center screen containing options such as Install Snow Leopard etc; ignore this. Go to one of the menus at the top menu bar (Almost certain its called Utility) and open Disk Utility. Then simply select your hard drive and repair.

(I would recommend you attempt to Verify your disk first by opening Disk Utility before doing any of the above - this could save you the fuss if that's not the problem, and you MAY even be able to repair without rebooting (try it, mine asked me to reboot so..)
