Has your drive SVC: NB52?

Check the UPDATE - 21/12/2021 in the first post there ----> viewtopic.php?f=16&t=22896.

It's an option, no need. Better have and do not need than need and do not have.

The WH16NS60 1.02MK is the recommended firmware for your drive. But theoretically, there could be a better firmware in the future.

Top Loading is imo more prone to defects.
The hilt with the connected technique is the weak point.

Thanks for correction / optimizing!

Just have a good look there -----> https://forum.makemkv.com/forum/viewtopic.php?f=16&t=19634 There you can find very good information, the SDF Flasher and firmware packs. The BH16NS55 just flash directly to WH16NS60 1.02MK. The BP50NB40 with NB52 needs a few more moves: " ..... NB52 to > B...

Libre Drive isn't enabled. You're sure you've flashed this drive for using it with MakeMKV? Edit: Sorry, I've just seen your copied text from the cmd. Something went wrong with the flashing process. The Flashing Guide says: " .....BP50NB40 to > BP50NB40-NB50-1.03MK then to > BP60NB10 1.02MK or ...

Thank you again for the quick processing

Look there at the top of the first post under the fat red subheading --> viewtopic.php?f=16&t=19634

The blocked process of the SDF flasher should have been good advice for you.....

It's bricked. Use the DOS flash way or buy a new one.

Even a good drive could become defective.

But first I would clean the lenses before throwing in the trash can.

You can also try to clean the laser lenses.
Do it with q-tip and alcohol (Isopropanol). Clean twice and dry immediately also with q-tip or a lint-free cloth.

I've no expierience in this case, but supposedly CrystalDiskInfo is able to get different datas from optical drives too. Google says: "Although mainly intended for hard drives, CrystalDiskInfo can also display information about optical drives, such as the number of read operations and other SMA...

Yes lenses are cleaned (with alcohol) several times.

OK, then I'll write it off as a curiosity. Happy with a working drive.

Thank you.

Yes, it's a combo, like the ASUS BC-12D2HT / BC-12B1ST also. But this combo is the first which has problems with the WH16NS60 1.02MK, I had four or fives of CH12NS40 in the past. An with the fw of the BC-12D2HT it has no problems with the same 3-layer discs. Could it be, that the blue laser is dying...

I've a curious handling with a CH12NS40. It had the original fw 1.00 installed which was 4k friendly and worked with MakeMKV. But that drive I normaly flash to WH16NS60 1.02MK. But with the WH16NS60 1.02MK no 4K disc will be recognized in Windows (before opening MakeMKV). Trying, trying, trying, sto...
