how to update Seagate hard drive firmware from DVD drive in G4 Powermac DA
Short version of story:
Just put Sonnet PCI SATA card in G4 Digital Audio Powermac running Tiger. Have replaced two IDE drives with Seagate Barracuda 7200.11 1 TB hard drive. It's recognized and working fine. EXCEPT: this is the now infamous drive ST31000340AS that WILL most certainly fail if it does not get the firmware update that Seagate has made available. (These drives are failing like crazy-- Google for info, do not buy!) I have the firmware update on CD as an ISO file (of course Seagate makes nothing that it Mac friendly but this has worked for other Mac users). But when I try to flash the firmware by starting from the CD ("C" key held down), nothing happens. The G4 just goes ahead and starts Tiger 10.4.11. I have also tried holding down "O + F + option + control on start up. I'm not getting anywhere.
Since the drive is functional and it's the only drive in the G4, what am I doing wrong? Help!
