I have two IDE hard drives, one is from my old computer; its a WD 80gb and my new one is a Seagate 320gb. My old hd is full (4% free space) and my new one shows 298gb. For some reason, it shows that I'm using 168gb but when I select all the folders (hidden ones too) in my C:\ drive, it says 121gb. I'm wonder wheres the other ~47gb? And while I'm at it, does anyone know how I can get the other 22gb from the 320gb?
