I just bought a 250 gig SATA drive and I have never installed one onto a machine. I looked at my mobo manual and correctly put in the corrections. When I try to run Windows XP Pro, it shows that I have 131069 MB of unpartitioned space. Now, I'm not math wiz, but 131069 does not seem nearly enough for it to be 250 gigs. Also in the bios, it shows my drive being in the "IDE Channel 2 Master". Am I doing something wrong?
