Re: Why is my 320gb hard drive only reading 141gb?
The first question, is the install disc old old XP? Or is it SP1/SP2? If it's the original disc I'd rip it to another PC and slipstream SP2 into it. A program called nLite is perfect for this and lets you customize the installer in many different ways.
Secondly, you can't. You have to backup what you want to keep (or ghost the entire thing to a file/another drive) then destroy the array and format the individual drives.
