I'm sorry because I get the sense that this will be a total noob question, but this is my first install in a few years. I installed XP onto a SATA drive as my boot drive. It shows up as 137 gigs, obviously. Now I've installed SP2, but it's still registering as 137 gigs. Is there anything I can do to open up the rest of the space on the drive? Or will I have to make some partitions?
