hi what is the maximum length that a firewire 800 cable can have? i'd like to leave my drives on the shelf and connect them to my computers without having to move them to the desk… thanks, alexandre 17" 2.33ghz ic2d macbook pro / 2.0gb / 160gb / X.5.5 24" 2.33ghz ic2d imac / 3.0gb / 1tb / X.5.5 iphone 3G / white / 16gb
