You mean ReadDataKey? FindVUK give it when i run it, so it "should" be correct, right?

I have rebooted and tried few times without running MakeMKV, i make sure it's not started, should i uninstall it completely?
I have updated today keydb.cfg and paste in %appdata% and VUKbackup folder.
I can see that in my previous post log in attachment is pending validation, so here is new log from run just few minutes ago.

Edit: i have uninstalled MakeMKV but still same result

Yes, RDK is "Read Data Key". And yes, I would expect FindVUK to extract the correct RDK from the dump.

No, you don't need to uninstall MakeMKV. Just ensure that you don't execute it when you insert your UHD disk into your drive. Once MakeMKV has activated LibreDrive, the drive is no longer bus-encrypted and so you don't need to decrypt it using the RDK.

Does your FindVUK.ini file have a

Disable_Bus_Encryption_Cmd = ...

entry? This can be another way of executing MakeMKV...

I have this in FindVUK.ini file:

[ExternalTools]
; Disable_Bus_Encryption_Cmd: command line for a tool which is able to disable bus encryption of the disc in the drive
;            Supports the following placeholders: $DRIVE$=driveletter (e.g. d)
;            Errorlevel=0 is taken as successful result, everything else as error
; Create_RDK_Cache_Entry_Cmd: command line for a tool which is able to determine the ReadDataKey of drive+disc and write it into RDK cache.
;            The RDK cache path is: ?FOLDERID_RoamingAppData?\aacs\rdk\<DRIVEID>\<DISCID>
;            Supports the following placeholders: $DRIVE$=driveletter (e.g. d), $DRIVEID$, $DISCID$, $FULLRDKPATH$
;            Errorlevel=0 is taken as successful result, everything else as error
Create_RDK_Cache_Entry_Cmd = 
Disable_Bus_Encryption_Cmd =

AFAICT, the entry in KEYDB.cfg for your disk is correct, including its Unit Key.

Did your drive support UHD disks "out of the box", or did you need to cross-flash it first?

Since the Unit Key for your disk is correct, the only reason I can think of for validation failing would be bus encryption. So either your RDK is incorrect, or bus encryption has been disabled on your drive somehow.

Can you use MakeMKV to create an encrypted back-up of your disk, and then play that back-up using VLC?

Or maybe delete this disk's RDK from your cache, set

Disable_Bus_Encryption_Cmd = hostname.exe

in your FindVUK.ini file, and then try validating the disk again?

Hi everyone,

I am getting the following error from an Asus drive when trying to validate a key from an original 4K UHD Bluray disc (it doesn't matter which one, I get that error for all disc titles):

Failed to init disc >AACS UNKNOWN ERROR >-1501

The drive can be used for ripping as long as the keys are known. Any idea?

Here is the drive info:
