This used to work just fine, but lately I have been having trouble getting my firewire HD to mount on my G3 iMac. The same drive mounts and works flawlessly on my Tibook. Rebooting and zapping the p ram worked once, but now even that fails. I have a g3 500 slot loading iMac running OS 10.2.3. Please help! This is crucial because my music is stored on the firewire drive and my burner is in the iMac.
