My friend recently got a hand me down Mac. It turned out to be a dual 1.42 G4. Yes, he is a lucky bastard. Anyway. The original 120GB hard drive is fine, but he wants to install a 2nd hard drive. It is a 40 GB Quantum Fireball, 5200 rpm. It DOES show up in System Profiler. It DOES NOT show up in Disk Utility. It is connected to the second ATA-66 bus. The original hard drive is connected to the 1st ATA-66 bus. The SuperDrive and a CD-RW we installed is on the ATA-33 bus. The drive is I think set to Cable Select, but may be a Master. Main thing that I can't believe is why it would show up in System Profiler but not Disk Utility. He says it is because it was formatted as NTFS in its previous life. I say there is something else wrong. It is his first Mac and he is kinda forced into using it (PC's motherboard broke). The easy of use has already awed him ("The disk images... they mount a disk and then the software didn't come with an installer, how do I install software?"). But this is something that is bugging me because it doesn't make sense. Any advice?
