ok, I lied, it's 2 questions. I'm wanting to hook my sony DRX-800UL DVD writer to my iMac, but I currently have my LaCie 500GB external hooked up via FW400. can I daisy chain from the LaCie to the Sony? I ask because the LaCie has 1 400 and 2 800 ports, so i'd have to go.. iMac via FW400 > FW400 LaCie then FW800 LaCie > FW400 Sony does that make sense? and would it work? also, what cable would I need to go from the FW800 on the LaCie to the FW400 on the sony? I tried ebay but it's all 6 pin 9 pin 4 pin stuff...I'm new to firewire. thanks Edit - also, would this have any effect on the performance of either device?
