Failed to open disc
Posted: Sun Feb 20, 2022 10:13 pm
I'm a bit new to 4K UHD, but I'm a quick learner. I've been using MakeMKV for well over a year now to back up my standard HD (1080) movies, and it's been working flawlessly! Now that I've (recently) made the leap to ALL things 4K, I'd like to back up my 4K UHD Blu-ray discs as well.
After digging around in this forum, I figured out how to free my ASUS BD burner from at least some of the shackles its been bound by. Using the SDFtool Flasher application, another GREAT piece of software, I flashed my ASUS BW-16D1HT with firmware version ASUS-BW-16D1HT-3.10-WM01601-211901041014. When I run MakeMKV, the Info section of the user interface displays the following;
Drive Information
OS device name: \Device\CdRom0
Current profile: BD-ROM
Manufacturer: ASUS
Product: BW-16D1HT
Revision: 3.10
Serial number: KLSK2L82559
Firmware date: 2119-01-04 10:14
Bus encryption flags: 1F
Highest AACS version: 76
LibreDrive Information
Status: Enabled
Drive platform: MT1959
Firmware type: Patched (microcode access re-enabled)
Firmware version: 3.10
DVD all regions: Yes
BD raw data read: Yes
BD raw metadata read: Yes
Unrestricted read speed: Yes
As I understand it, the LibreDrive info is the good stuff (?), and in theory, this drive should be able to back up my BD UHD discs. Maybe? However, after several minutes of chugging and chugging on the very first 4K UHD disc I tried to back up (The Fifth Element - 20th Anniversary Edition), MakeMKV displayed the following;
Disc Information
Label: FIFTH_ELEMENT_THE
Timestamp: 2017-05-17 14:13:04
Protection: AACS2.0/C v61
Data capacity: 60.37 Gb
Disc type: BD-ROM UHD
Number of layers: 2
Bus encryption flags: 80
MakeMKV v1.16.5 win(x64-release) started
Using LibreDrive mode (v06.2 id=0FA242DD4D0B)
Using direct disc access mode
Loaded content hash table, will verify integrity of M2TS files.
Saved AACS dump file as C:\Users\AL/.MakeMKV/MKB20_v61_Fifth_Element_C175.tgz
The volume key is unknown for this disc - video can't be decrypted
Failed to open disc
I assume the 'volume key' is an encryption key of some sort that's needed to decrypt the .M2TS files, and without that key, well ... the obvious result is the "Failed to open disc" message from MakeMKV. Also, what's the purpose of the MKB20_v61_Fifth_Element_C175.tgz file?
The other interesting part of this is that a standard Blu-ray disc (1080 format) was also in the case, which MakeMKV had no trouble backing up at all. Not exactly what I hoped for, but better than nothing at all, I guess. At any rate, after Googling "Blu-ray volume keys" I ended up on the 'MakeMKV FAQ - How do I pass volume key to MakeMKV?" webpage, which also provided the following link; https://forum.doom9.org/showthread.php?t=120988
And that's as far as I've been able to go with this. So far, I only have ten 4K UHD movies, but I'd really like to back them up. I don't fully understand what to do with all these Blu-ray keys that appear to go all the way back to 2009, but my guess is to put them in a text file and put the file in the MakeMKV directory? The other link provided on the above linked webpage points to this page - https://forum.doom9.org/showthread.php?t=120988 - which is page 9 of 28 pages of volume keys.
More questions; has anyone compiled ALL the keys into a single file that's correctly named that I can download and copy to the MakeMKV directory? Or do I have to do all that copying and pasting myself? Also, what's the name of the file supposed to be so that MakeMKV will open and read it? Are ANY of my assumptions correct?
One last question; what are the odds that ALL of the 4K UHD movies I purchase will be in the same boat (so to speak) as "The Fifth Element" movie and I won't be able to back up ANY of them without the keys?
