Fautly drive? It keeps changing from being a DVD-RW to a CDR in my computer which makes the system hang when I try and access anything on it. Updated the firmware which made it work for a few weeks then today again it went back to wasting discs I was trying to burn and that message appearing in device manager. Updated the firmware again and it's working fine again. Weird thing is after it's died the volume name shows up as a disc I burnt several weeks ago despite that disc never having been back in the drive since and a different one in there at the time. Not the fault of the media as I have two decent brands and there's been problems buring both - the firmware apparently disappearing is a concern but I've tested the discs that it's done recently and they've all been fine.
