Heres the deal. My mom is getting my G4 400MHz, and I am getting the G4 500Mhz. The G4 500 has 4 30GB hardrives in it. The G4 400 has one 80GB Drive in it. I am going to keep the 80GB (its mine with my files), and I am getting one more 30GB Drive. My mom is getting one 30GB Drive. Another 30GB Drive is for backup, and the last one is for video projects. So, I have 15GB of Movies, 5GB of Music, 8GB of .dmg and .sit files (lotta programs ), 1.5GBs of Documents, and about 400MB of pictures. Ok, so how should I set up these 2 drives. I want the 80GB to be my bootup drive because it is newer and faster. I am going to reformat both drives for OS X, but I just dont know what files to have on what and stuff. What do you guys think?
