Hardware: Titanium Powerbook G4 400MHz Original HD: Toshiba 10GB 4200RPM My system froze (10.3.2) and after restarting it couldn't find the HD anymore. I ran the OSX installer and recovery CD's, but nothing, so I decided to buy a new HD (Toshiba 40GB/5400RPM). I have replaced the HD and still nothing. It finds the external firewire HD during OSX installation, but not the internal one. Any ideas on what could be happening? Thanks!
