We've been mac users for years and right now I'm stumped. We have a dual G4 (867 mirrored drive doors) running 10.4.10 and firewire has just stopped working. I have a Kanguru external drive that has both firewire and usb interface. When connected to usb, the drive mounts, but not when connected to firewire after a restart. Two other firewire drives are no longer recognized either. Nor is my Canon digital video camera recognized. Has anyone else had this problem?
Disk utility and Disk Warrior can not recognize the firewire drives either. FSCK and Techtool can not identify the problem either. Diagnostic in about this mac lists no errors.
P.S. We have an internal HD with 10.2.8 and when booting from this disk no firewire either. Pulled all PCI cards and still the firewire drives are not recognized. Also reset pram and booted in single user mode to run fsck -fy but no issues. Also tried PCI firewire card. It is recognized by the computer but firewire externals still not recognized.
Is that the only firewire port you have? I know that (at least with fw 400) the ports on firewire are very sensitive, and that disconnecting something connected to the port without properly ejecting it will burn those things out and just plain kill the port, electrical surge or something. I've worked on G5's and mac pros in a lab-type environment and sometimes I'd have to try a few computers to find one where someone hadn't burnt out the firewire port.
Also are you using the same FireWire cable for all the drives connected too that MDD? I have 2 FW cables that have issues with one end and will not work.
Ooppsy.....
