Oh, and yes, I did try it on another Mac, and it didn't work. And I tried it by booting to OS 9.1 and it didn't show either. <br><br>Another thing I noticed...sometimes the System Profiler doesn't even recognize the firewire drive. Then if I play around with unplugging and restarting, I can get it to recognize that something is connected to the slot, but the drive still doesn't mount.<br><br>
