My internal hard died in my g4 powermac. I swapped it out with a similar deskstar 60gig I had. I installed it. Pretty sure I have the jumpers right. I did a clean install of 10.4. When I try to restart, I get the folder guestion mark thing. When I boot with the mac os dvd, I can do a disk utility on it and it passes. In Startup utility I can choose it. But when I restart, nothing, I ran the full suite of techtool pro tests and all hardware including the drive passes. What up?!?!
