I an using Win7 Pro and my DVD device no longer shows up with all my other devices and drives in the "Computer" window. Thus when I try to read a dvd the system no longer recognizes the device as available (or exixting?) on my system, whereas yesterday it worked fine.
I tried the MS diagnostic but that returned no error?
How do I fix this problem? [I presume if it was dust in the DVD this would show as a read error, but at least the device would show up as existing?]
