Thanks, I'll look into that list. Must have missed it the first time through.

Hi Tab,

This isn't really CoreAudio, but I'm not aware of any hardware-oriented

On OS/X, how can I find out the IDs of unmounted CD-ROM drives? I need
to provide a list, and possibly talk to (if only for the purposes of
giving an 'eject' or 'inject' command) all CD-ROM drives, whether they
have a disc in them or not. This was possible under OS/9, but under
OS/X, a drive doesn't exist until it's mounted, which is very unix-ish,
understandably, but leaves me with the problem of finding the drive
before it is mounted.
Any ideas?
Thanks

I suggest taking this to the ata-scsi-dev list:
<http://lists.apple.com/mailman/listinfo/ata-scsi-dev>
The short answer is that drives without media are only visible at the I/O
Kit level. By querying the I/O Registry, you can basically build the same
device list as you see in Apple System Profiler.
Thanks,
