Hello, I have an HP Pavillion zv6015us, it has a DVD-RW in it. I am having a problem with that drive. when I look at it in MY Computer, it says that it is a DVD-RW , but when I put a DVD disc in, it says that it is a CD Drive and it will not recognize DVD's, even ones burned using that very drive a few months ago. Can anyone tell me why that is and what I can do to fix this?
