Thanks for the responses..
Yeah, I’ve done all of the regular quick fixes…Re-boot, disk utility (w/ usb connection), disk warrior, even zapped pram. I used to think it was a problem with the drive…but once I realized that my other external firewire and my ipod wouldn’t mount I’m thinking it’s either software or a hardware issue with my tower.
I’m not completely sure on the inner-workings of a G4, but are both firwire ports connected somehow?
