So i have the new I7 Imac. I have a Duet and a Powered G drive. The Duet takes firewire 400 and the GDrive takes fire wire 800. But my imac only has one firewire 800 port. So....... am i able to run my duet daisy chain off my g drive? it would be like this Duet--(FW400)-->Gdrive--(FW800)--> Imac. Is this going to cause any issues for my duet or my imac?(power and performance wise)???
