XP does that. Here's a read about it -> http://www.abit-usa.com/faq/mb/2002031801.php
I'm running xp pro and my 60gb hdd is reported as
31.4gb. It showed up the same before upgrading to xp from 98.When first installed correct size was reported , I had to wipe all drives after a crash while running 98 and problem is only since them.Before the crash everything was ok.
Any suggestions please
