Actually, your problems might go away if you put each drive on its own separate FireWire bus. There have been a number of reports of flaky behavior, even data corruption, from putting multiple high bandwidth devices on one FireWire bus, which exceeds the bandwidth of your FireWire bus. You may have heard about this with regard to attaching both an iSight and an external FireWire drive to one FireWire bus and using them simultaneously. Some folks have reported completely corrupting their hard drive from doing this. I'd love to give you citations for this, but the ones that I have are all to Apple discussion lists, and Apple has a way of removing discussions that aren't terribly flattering to Apple... Randy B.
