I got a new DVD-RW (Pioneer DVR-111D) drive, installed it into my “new” office main PC, but after a reboot, the drive was not detected.
The tray ejects, the front panel LED lights up, all the cables, power, etc is correct…
A look at the device manager (control panel -> system -> hardware -> device manager) shows that there is some problem with the registry. (an yellow sign, and an error 19).
A quick search finds: http://support.microsoft.com/?kbid=314060
Removing the upperfilters and lowerfilters registry keys did the trick.
