Hello all. I have a 1TB WD Caviar Blue HDD in my newly built gaming rig. I had striped it from a old computer and on that old computer it had the C partion which was around 150GB and the D partion which was the rest. I want to make a setup exactly like this if possible. But when i go to create the partions in the windows disk managment it only allows me to bring the C Drive to 470GB which dosent make sense, im only using about 25GB on the C partion currently, why wont it allow it to go down further? Any tips?
