firewire drive
I just purchased a triple interface Lacie drive to put clips on while using final cut. the problem is final cut wants to send video through the firewire port….result is hanging system. Are there settings to correct this or do I have to put the drive on USB? I’m only using it for dv25 with minimal effects but I would prefer to use the firewire 800 port to limit the dropped frames etc. Any solutions? thanks

In your profile it says you are using a Decklink card. I don’t use this card but I would imagine you could monitor your video output from this card under the Video Ouput settings in FCP (Final Cut Pro>Audio/Video Settings>Video Playback>Decklink). You should be able to use the FW 800 port on the LaCie drive and still monitor using the card. Give it a go.
Good Luck

I use a decklink card on my desktop g4’s and g5’s…..this drive is for my laptop ie. no decklink card. I use an external firewire to analog video converter to monitor.

You need to get a FireWire 800 PC card for your PowerBook. All Macs come with only one FW bus, regardless of the number and type of ports/connectors. Doing disk I/O and sending a video signal over the same FW bus can be very problematic.

Oh, I forgot to mention that you should avoid using USB with video like the plague.
USB is a “burst” data transfer protocol and it’s not good for sustained transfer of large amounts of data (video files, for example).

I was afraid of that thanks….as far as the USB being bad for video,? Do you think it can handle dv25?

=====================No. It’s not a matter of the data rate…USB2 is certainly FAST enough for DV. It just wasn’t designed for it. It may achieve very high speeds for a moment and then drop to nearly nothing at the next moment. Firewire was built to sustain a constant rate.
So if you’re measuring the copying of files from one drive to another they’ll end up being about the same, but if you’re trying to capture video from a deck you’ll end up being unhappy with USB.
