Hi there, I'm trying to replace the internal HD on a 5oo MHz Powerbook G4 Titanium. After fitting it, I boot off the DVD but Disk Utility cannot find the new drive. I cannot hear it spinning either, suggesting there is a power problem. I immediately want to blame a DOA drive, but more likely I have made a mistake. I have checked the connections twice - all seems fine there. I have followed the directions as outlined here, but I am still having trouble. Going to try putting the old one back in now, to see what happens... but if any of you brght people have some ideas please help! It's a Fujitsu 60GB ATA-100 drive.
