I have tried this but, as I originally posted, the drive will no longer recognise ANY DVD - not even a regular pre-recorded one. It "thinks" it's a CD drive now, and will only recognise CDs. If I put a blank DVD in the system just beeps a few times then ImgBurn reports "Device Not Ready (Medium Not Present)". I have tried several blank DVD-Rs (both Datasafe, which has always worked before, and Datawrite) and have also tried store-bought DVD movies that play in other machines.
