I have a Maxtor Firewire drive. I purchased a LaCie drive yesterday. My other Firewire port is taken up by an iSight. Therefore, I plugged the LaCie drive into the back of the Maxtor. The Lacie icon shows up fine on my desktop. However, the red light on the Maxtor stays lit and the Maxtor icon does not show up on my desktop. Am I right that I should get a Firewire hub instead of plugging the LaCie drive into the Maxtor? I read somewhere that Firewire does not have enough power to accept pass-throughs and thus need a hub. Is that true? By the way, I own a PowerMac G4 500 (Sawtooth).
