I am trying to use my external hard drive (Western Digital 250GB 72000RM Firewire) for video editing (Final Cut Pro) on my laptop apple: iBook G4). I purchased the external hard drive to give me more space for the purpose of video editing and the external hard drive is connected by firewire to my laptop. When I connect my miniDV JVC camcorder to the external to begin the editing process I connect it via firewire as well. When I open the editing application and begin to log my video it at undetermined times freezes and the sound begins to skip like a CD and the rainbow ball displays showing that the program is working. The sound stops, but the ball continues spinning and when I go to the icon on the dock to "force quit" it has in the menu as well "application not responding". Does anyone know why I'm encounterting this situation or issue and what am I doing wrong? Has anyone experienced this as well and if so please lend your expertise and opions for resolution. Thanking you in advance.
