Just for curiosity...Have you ever thought about PT HD Native?
hang on.... you can't daisy chain a 2626 and an external firewire drive?????
FUUUUUUUU
The order depends on what works best. I usually have drive last in the chain.
Turn everything on before the computer and you should be good.
Don't mix FW 800 and 400 devices. So if you have a drive capable of FW400 you have to use the 400 ports on it.
