W7Pro is suppose to only take up to 16 Gigs according to Google. I havn't even installed drivers, I"m sitting on some insanely ugly resolution typing this right now. I have 62 Gigs out of 111 Gigs free. What could possibly be causing 50 gigs to not appear? It is a 120 Gig drive (SSD). Also, I'm starting to think I should leave my SSD for Games only, and install the OS on a different hard drive. Unless having the OS on a different Hard Drive will impact performance.
