The problem is simple, when I go to Computer, I don't see my DVD drive, however I can still open/close it. I haven't been using it for couple of months, so I'm not really sure at what point did it stop working.
Sorry that the screenshot isn't in english, basically:
- C: & D: - first and main parititioned HDD
- E: - USB device
- F: G: H: I: - memory card reader
- L: - second HDD

And one even funnier thing, when I mount an ISO image in Daemon Tools, it also doesn't show up. It just seems that Windows isn't happy with any kind of CD/DVD drive.
I'm using Vista Business x64.
