Programmer's question: How to detect DVD+R/W support?

[vio_man]

I would like to ask if someone can explain me how to detect if a DVD drive supports DVD+R/W reading/writing (using C++).

Thank you.

Go to www.t10.org/drafts.htm and download the MMC documents (versions 1, 2, 3 and 4) and read the MMC command set. In particular, check the GET CONFIGURATION command (46h) and DVD+RW feature (002Ah).

cfitz, is there ANYTHING you can't find?

EDIT: Doom9.org has a programming forum; also, since all most all Linux software has source code, you may want to take a look at some of the Linux burning programs; they (mostly) use the SCSI (or SCSI emulation) for burning, so the commands should be the same.

I don't think the phpBB software will accept a post long enough to list all the stuff I don't know and can't find. Ian would have to buy a new server with a multi-terrabyte storage array.

In this case, I just happened to have looked at those documents before, so I knew they exist and have lots of (rather detailed low-level) information in them.

Yeah, I'd have to say that cfitz has the most helpfull posts on these forums. It seems like he spends too much time typing lengthy anwsers for questions...

Thanks for the kind words, aviationwiz, but I'm just a generalist, so my knowledge isn't very deep. And I think Inertia does the best job at providing thoughtful, in-depth answers to questions here.

As for long answers, you're right. I do tend to be too wordy in my posts.
