Somehow LOTR did not work for me. I restarted MakeMKV several times - also tried different discs.
Only after I restarted MakeMkv and inserted at first another (older) UHD disc everything was fine.

(I am using an external drive)

I did all these things already.
Only with the replacement I tried 1.14.3.

I am confused why 1.14.4 says that there is no disc but 1.14.3 says there is.

Asus BW-16D1HT 3.01 Version 1.14.4 tells me always that there is no disc inserted. With version 1.14.3 the drive make several minutes terrible sounds before it starts Perhaps this will help: MakeMKV v1.14.3 win(x64-release) started Debug logging enabled, log will be saved as C:\Users\Rainer/MakeMKV_...

Log files: I got several times something like 001011:0000 DEBUG: Code 03DF/03/E064BA3E3F81 DEBUG: Code 2147483648 at z3q2Zsw5q;dm{R\<:121265223 005085:0000 Loaded content hash table, will verify integrity of M2TS files. 001003:0020 DEBUG: Code 3221225628 at lWJ!.;^m82Xk/T<8[g6r6&f*:213130398 001003:...

The guide was fine and the downgraded one (3.01) shows now the disc. I also can backup now my disc which caused problems: https://www.makemkv.com/forum/viewtopic.php?f=12&t=18233 One disc broke - it had certainly a hidden damage.

Thanks for that info.
I always thought that I could see the disc. But decryption was not possible.

I have here 2 ASUS BW-16D1HT - one with v3.02 and another with v3.03 I know that the 3.03 is UHD unfriendly. I want to downgrade the firmware. (didn't start the downgrade yet) But the drive does not read the UHD disc. When I insert an UHD disc then Windows & MakeMKV say that there is no disc inserte...

It seems to be the disc.
After trying several times the drive became very warm.
And when I ejected the disc now - it had a crack.

Thanks! I tried https://www.makemkv.com/download/ and https://www.makemkv.com/download/Setup_MakeMKV_v1.12.2.exe and couldn't find the old versions. Edit: Version 1.12.2 showed the disc but I got the following errors Error 'Scsi error - MEDIUM ERROR:L-EC UNCORRECTABLE ERROR' occurred while reading '...

I don't find an official download link for version 1.12.2

I tried to clean the discs before - with no luck.
I use MakeMKV v1.12.3 win (x64 release).

But shouldn't the file manager of windows show the files of the discs - regardless of the version of MakeMKV?
Or are some discs always being 'hidden'?

I have a Asus BW-16D1HT and no stand-alone-player (so I cannot verify whether something is wrong with the not working discs). The Asus is connected via SATA-USB-Adapter. The drive works with some discs. I was able to copy the UHD Kong: Skull Island & Atomic Blonde. But with 2 other UHD I have the pr...
