Mac OS X 10.4: Removable media devices not mounting, fixes
Some users experience problems with recognition of a removable media devices (particularly CD and DVD optical drives) under Mac OS X 10.4.
In some cases resetting NVRAM can resolve this issue. This is accomplished via the following procedure:
Start up into Open Firmware by pressing and holding the Command, Option, O and F keys simultaneously combination during startup.
At the prompt, type the following commands, one by one, pressing the return key after each (your system will automatically restart after pressing return the last time):
- reset-nvram
- set-defaults
- reset-all

"I was having this same issue (SuperDrive in my iBook not a recognized drive)
"I just tried doing the 'Resetting NVRAM' procedure, and while I don't have any of my DVD-R discs here to test officially, my drive is recognizing a CD-R I just inserted."

I inserted a DVD and the DVD software started up but the DVD didn't appear on
the desktop and the software couldn't find it. I tried resetting NVRAM as
recommended above and it fixed the problem.
Still no DVD Media mounting on G4 with a Toshiba SD-R1312 drive.
No matter if commercial movie or data-DVD.
The second drive - a pioneer 107 - works though.
any more hints?
