Forgive me if I am re-asking a question that has already been asked but I am stuck. I just bought a new hard drive (320Gigs) that I plan on using for my new system build. The problem that I’m having is this. When I load Windows Vista Home Premium on the dive it only recognizes around 290 Gigs. I have already reformatted the drive from the manufacture so that's not the problem. I do expect some over head but 30 Gigs is too much. So does Vista have a problem with larger drives, or do I need to check the jumper settings on the drive. I would hate to have to waste that much extra drive space. So any advice would help. Thanks.
