It's not a bug and fully explained at http://www.48bitlba.com
I just installed Win XP (what a nightmare), but windows only shows the capacity of the drive as about 130 GB (the capacity is 300 GB). How do I fix this? Right now the hard drive is connected as a SATA 1, but is a SATA 2 (was switched because of problems). If I switch bach to SATA 2 and format from Win XP will it format the whole thing or just the part that windows sees?
