When a drive starts to get old (2 years is old for these drives) and I will not enter into a debate about how lifespans have dropped over the years but the issue of media detection is something well done.
I don't see any words if you cleaned the lens but if DVD and BD is find but all makes of CDR fail that can point to a laser failure. http://www.pcworld.com/article/14697/article.html gets you up to speed that there are TWO LASERS.
So try the cleaning, other media and a new drive if the prior work fails. Here I opted to not replace the drive but use some USB DVDRW for the rare occasion.
I have a Samsung NP-RF711-S03UK laptop with TS-LB23A optical drive, just shy of 2 years old. Today it has started acting up and will only recognise certain recordable media.
When I insert a blank CD-R it says there is no disk.
Discs from the same pack that have previously been written are recognised no problem.
Tried 7 different brands of blank CD-R, none recognised.
It reads bluray fine.
Recordable DVDs, no problem, Reading and writing fine.
I have tried all the fixes I can find on the net (uninstall and reboot, microsoft fixit e.t.c.) but no joy.
Does anyone have any idea what is going on?
