Drives on my G4 1g (FW800) seem to be "disappearing" within Jaguar, with the exception of the startup disk.
I installed a secondary drive in the back bay next to the stock hard drive. That drive (i'll call it Drive2) mounted as expected after starting up, so I shut down again and decided to install a third ata 133 drive in the front bay. Instead of using the mainboard's ata66 controller, I installed a Sonnet Tempo ata133 card and attached the third drive (i'll call it Drive3). Drive3 mounted as expected after startup as well as Drive2. Jumper settings on both drives were set to cable select, since that's what the G4 manual prescribed. So far so good.
I shut down again and installed a fourth drive - 40gig ultra 160 scsi drive - hooked up to an Adaptec 29160 card. I booted up but received an error prompt asking me to restart the Mac. I did this 3 times but it refused to startup normally, so I disconnected the scsi cable from the drive, and restarted. I was able to get to the desktop but Drive3 didn't show up. OS X's Drive Utility could recognize Drive3 was attached but couldn't mount it or run Disk First Aid on it. So I restarted the Mac, hoping it was just a glitch. Now Drive3 AND Drive2 wouldn't appear on the desktop. Drive Utility could recognize both drives but couldn't mount em. I shut down and removed the Tempo ata 133 pci card and attached Drive3 to the mainboard ata66 controller, then booted up. No difference.
At this point I was thinking that the venerable DiskWarrior would fix whatever problems were on the drives. DW couldn't recognize both drives. Micromat's Drive 10 was able to run tests on both drives except for rebuilding volume structures. And Norton is banned from this scenario.
I don't know what to do at this point. This setup worked flawlessly on my G4 733 Quicksilver. Any ideas??
