What is wrong with my DVD Drive?

My CD Drive in my PC hasn’t been working right. It works for CD-ROMs, CDs, and is supposed to work for DVDs. I know for sure, because it has the DVD logo right on it. But when I put in a DVD it doesn’t even acknowledge it. I was told that I could just need to download an update for it, after getting the model number or the type of drive. So a kind of secondary question is how to I find the model number or type of DVD Drive I have?
