Sorry I lost the logs. Now it won't even recognise Blank DVD-R's. When I insert it just makes sound as-if balancing/adjusting it. And it keeps balancing it.
How old is this drive ? I had a drive do this, and then it lots features until it no longer worked. First it started by being picky with respect to media.

Rep:
not 100% sure but i believe so as they are different frequencies or different power output or something like that, however according to wikipedia the lifespan of a dvd recorder laser diode is about 2 years
