Hi Dave

Thanx for the reply

Let me try to understand you?

You say;
"Don't try to copy a Leopard disc with Tiger" that threw me a bit.

Allow me to explain what I'm doing now;
I have tons of video media on 5 external Lacie's. I also have #4 1TB OWC external drives that I use for back up of all that data from the #5 Lacie's. I use Final Cut and Super Duper within a Tiger environment. I'd like to multi-task and load Super Duper in the other G5, (that has Leopard), and continue with back up's, cloning (using Super Duper Smart Update), to update from the Lacie's to the OWC 1TB drives. *They're all external drives.

Always going from the external Lacie's to the external OWC 1TB drives.

Is this possible? Will this work? Or is there a possiblity that the updated data may confuse the G5 with Tiger? Especially in the event of a crash when I'd have to rely on the back up drives to reconnect all that media.

Thanx
Mike
