I just built my first computer with a 1 TB SATA Hard drive. And me, wanting to be pro, partitioned the hard drive. I wanted drive C to house the OS and be separate in case of updates or reinstalls, and drive D to be used as general storage. When I installed my first game of choice(Minecraft), the launcher said "launching from C:\yaddayaddaya." I wanted it to be installed on and launched from drive D. Should I just backup important data and do a total reinstall with no partitions, or How do I make sure that anything I download go to Drive D? And how do expand Drive C?
