I have a weird issue with my new laptop (Asus N76VM). Every time I open iTunes it makes my DVD drive make a spin up noise for a second and then stops. It seems like it checks if there's a CD present or so (but there isn't, it's empty). I would be able to live with it if it just occurs on iTunes startup. This is not the case, even if iTunes is minimized and then I open the iTunes window again, the DVD drive spins again. This is very annoying. What could be the reason for the spinning? How can I stop it?
Note: this problem is both when running on battery or power cable.
