Hey guys, whenever I connect an external HD via Firewire to my Powerbook G4 (1,6 GHz, 15", 1,5 GB RAM) either everything freezes after 2-3 minutes or I get a Kernel Panic. Same thing happens when I connect via USB. I had a similar problem some weeks ago, I had freezes and Kernel Panics whenever listening to music or watching a movie. I formatted the System HD and reinstalled the system. Since then everything has been working fine - till today when I bought the external HD to make backups. I tried booting from CD in order to make a backup by using the hard disk utility - Kernel Panic. When I keep the external HD unplugged, no problem, freeze, panic at all. When I plug it in - freeze or panic after some minutes. Help !
