I've noticed that Carbon Copy Cloner, PsyncX and SilverKeeper stall and fail to complete backup (clone) of my internal 60GB ATA drive to my Lacie Porche Design 160GB Firewire drive since updating to 10.3.4 on my G4 Quicksilver 933mhz 1GB ram. Disconnecting iSight seems to resolve this problem...I think. Is it possible the (2) firewire ports on my G4 are some how interfering with each other
