I just reinstalled windows 7 x64 Ultimate and then installed the drivers off Nvidias website for my GTX470. I open up My Computer and now all I see is my 40GB Intel X25 40GB SSD drive and my 500GB WD 7200 RPM Drive is missing. They both show up in my BIOS. I formatted the 500GB harddrive before installing windows. Where could it have gone!?
