Tom, It sounds as though you need to check with MacAlly. Since they aren't using the Oxford chip set as a bridge, I'd suspect that some sort of incompatibility exists between their bridge and Apple's implementation of Firewire drive mounting. It sounds as though people with recent FW 400 and 800 drives using current firmware for the Oxford chipset are doing OK with 10.3.6.
