OS 9 Doesn't recognize DVD drive

I have a Powermac G4 533mhz with a HL-DT-ST DVDRAM GSA-40818 drive. I think this is an LG drive. The drive works fine in OS 10.4. but when I boot to 0s 9.2, the cd won't show up. I should also mention that I connected a firewire CDRW, and cd's won't show up in that one, either. The OS 9 comes from an "install disc" for Classic. but I can boot to OS9, and everything works except Cd's don't show up. Any ideas?

Powermac G4 533mhz Digital Audio, Mac OS 9.2.x

System profiler says it's a cd-rom, but its a dvd writer. under drivers, it says "not available"

You might need to modify a burn support plugin for OS 9.
It's fairly easy.

Hi, orionexp -

While booted to OS 9, make sure these items are enabled (checkmarked) in Extensions Manager control panel -
Apple Audio Extension
Apple CD/DVD Driver
Apple Photo Access
Audio CD Access
Foreign File Access
ISO 9660 File Access
UDF Volume Access

File Exchange (control panel)

If you needed to enable any of those, restart to make them active.

What version of the extension named CarbonLib is installed in your OS 9?

Hi Don,

Interesting results. I checked under "9.2.2 All"

and the only one i could find was UDF Volume Access.
This makes me wonder, is it possible the version of 9.2.2 that I have is for CLASSIC only under OS X?
so it doesnt need to have any of the CD/DVD drivers? (Because OS X will be handling those chores?)
Don't know enough to confirm that, but if true, then I will need to get a hold of a REAL OS 9 install disc (I'm hoping my dad will have one.
Thanks,
Steve

Hi, Steve -

My error - I shold have asked you to physically check the contents of the Extensions folder for those. Not all will appear in the list in Extensions Manager.

However, the critical one is the one named Apple CD/DVD Driver - that one is needed for OS 9 to be able to mount a CD in the drive. It is one that should appear in Extensions Manager - if it does not, then it is not present, and is likely the reason that disks won't mount when booted to OS 9.

The others are used in order to recognize certain file types on the disk.

If you are missing some, particularly Apple CD/DVD Driver, you can obtain them by downloading the appropriate OS 9 download update. You can use the utility TomeViewer to extract (expand) any files you want from an Installation Tome on an OS Install CD or download disk image, without running the installer.
How to use TomeViewer

If you are using OS 9.1, download the update for OS 9.1. If you are using OS 9.2.1 or 9.2.2, download the update for OS 9.2.1 Update - most of the file versions in OS 9.2.2 are also used in OS 9.2.1; in this case, all the files I listed are in the OS 9.2.1 download update.
