Well, yes :D What you want to investigate is the IOKit Registry. I don't have the sample code on this machine, please have a look at this: https://developer.apple.com/library/mac/#documentation/DeviceDrivers/Concept... If you encounter problems let me know. I have the sample code somewhere Alex Am 04.02.2012 um 10:25 schrieb Alex Reynolds:

I'd like to discern read-only media from optical media, as well as get information about the optical media.

Basically, I am looking for information about the programmatic equivalent of running "diskutil info /Volume/XYZ" and getting "Optical Drive" and/or "Optical Media" entries when a CD or DVD is inserted, which are not visible for other mounted media.

Does this help clarify?

Thanks, Alex

Knowing what you want to do with this information helps to give you a better answer

Is there a programmatic method by which one can determine if a mounted disk is optical, e.g., CD or DVD?

Thanks, Alex
