I've just added a WD800JB hard drive to the ATA66 slots on my new Powermac ( it came with 2 120Gb drives in the ATA100 slots ) to try and optimize my photoshop use. The drive doesn't appear on the desktop however, despite having the jumpers set to Cable Select as per the G4 setup guide. It does show as a Hard Disk in the System Profiler.
What am I missing . . ?
