<<<<<<<<Did you have, by any chance, a warning sheet with your ZD as to how to operate it with Firewire>>>>>
I know, you didnt ask me, but I still answer: I never saw such info. But it would be very interesting to know if there is a certain procedure to follow. Just yesterday in the middle of a production it happend again: after an our of tethered shooting the files to be transfered go stuck in the middle of the cable somewhere, the camera tried to send them to the mac, where they didnīt arrive. which means the buffer doesnīt clear. You cant even switch of the camera because it is warning you, that there are still unsaved files somewhere around. You have to take the battery out to solve the hick up.
This firewire-thing opens a whole new hobby to me - collecting firewirecables. Every time when I am shopping with wife/kids I take a stroll through the electronic department inspecting and sometimes bying firewire cables - on my quest to find the ultimate-ZD-cable. (some do actualy fit better than others).
