Don't know what your setup is but check this out. I actually had the same problem with some 450 G4's. Was trying to use both Firewire ports, one for a scanner and one for a burner. Turned out both ports were good but could only use 1 at a time. Overloaded them I guess. So I switched the burner to usb and worked fine. If your not already try just using one of the ports. > ---------- > From: Diannah Morgan > Reply To: Power Macintosh G4 List > Sent: Monday, July 14, 2003 11:26 AM > To: Power Macintosh G4 List > Subject: [G4] Dead FW ports > > Hi, > > I've got some old G4-400's in a classroom and I believe I have dead FW > ports > in some > of the machines.
