Okay, I know it's possible, but last night I couldn't get it to work. Here is what I did. -Turned both computers on. -Connected Firewire cable to both computers -Restarted the computer I wanted to run as a FW HardDrive while holding down "T". The conputer did start up in FireWire HD mode alright, however it wouldn't show up on the other computer. (it is supposed to show up on the desktop as another hard drive right?). Is there a step I missed? Do I need a special FireWire cable? New computer is OS 10.3 and the other computer is OS 10.2. Thanks.
