Samsung RF711 Doesn't recognise certain blank optical media

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?

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. 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 don't think it is a laser issue

Thanks for the quick reply.

I thought there were 2 lasers as there are 2 lenses, I cleaned both lenses with compressed air and a microfibre cloth.

I don't know if one laser handles reading and the other handles writing, or one is for BD/DVD and one is for CD, but CDRs with data on are read ok, and as I said BD and DVD read & write no problem.

The problem is unique to blank CDR.

Do you know any TSST specific forums I might try?
Google is not helpful.

I'm sorry but I must bow out.

I've learned to bow out when folk want to fix such drives. We do the usual cleaning and if they pay, firmware updates if available but the cost of a new drive is far cheaper than the bench time and there are no parts available to replace in the drive.

And for the client that pays we can show the drive fail on other PCs since it's a bog standard SATA connection.

Good luck,

(NT) PS. Be sure to read that last link about packet writing.

Looked up the firmware just in case.
