Errr, have you? Your first link still hasn't had its "Share" option updated, your second link is for your MKB_RO.inf file, and there is no third link???

Thanks, and these log messages indicate that your UHD drive has not enabled LibreDrive:

However, you also seem to have ripped your "Season 2 Disk 3" disk correctly, and so this is likely a transient problem. I suggest ejecting the disk, waiting for a bit and then reinserting it and trying again. Hopefully, MakeMKV will generate a usable TGZ file next time.

it does seem that one disk randomly works and then another doesn't so I suppose my only option is to eject eject eject until it works? (I'm not sure what a libredrive is unfortunately)

It might help to wait until the disk appears in Windows File Explorer before launching MakeMKV.

The public KEYDB.cfg file only has a partial entry for the MKB20_v82_ARCANE_SEASON_TWO_DISC_TWO_7E25.tgz disk, and so we'd be interested in having a usable dump.

Yes please :). When MakeMKV finally manages to enable LibreDrive for your "Arcane Season 2 Disk 2" disk, can you create a discatt.dat file for it please? Basically, use MakeMKV to start creating an encrypted disk back-up into a temporary directory, wait until the discatt.dat file appears (and it should be one of the very first files), copy it to a safe location and then abort the back-up.

is this time sensitive (like is it impossible once its fully complete?)? because makekv is currently managing to make a backup of episode two after a few tries, it's roughly half way through atm, could you give me suuuper clear instructions as to what you need form me aha

edit: Ive found the dispatt file, did you mean to say abort the backup only if I'd already backed it up? as in I can just copy this and continue the backup?

If you're already successfully creating a back-up of disk 2 then could you just grab a copy of the discatt.dat or discattd.dat file and upload it please? No need to interrupt anything :).

great, alrighty I've added that to the google file, let me know if I need to make a new link to share it aha

are there any other things you need from this season? do you mind if I ask what the discatt.dat file helps you with? (that's just a question out of curiosity more than anything aha)

Thanks, I'm hoping this is enough :). The discatt.dat file contains "disc attributes", which are extracted from the disk's "lead in" section before its UDF filesystem. The drive reads these attributes in while mounting the disk, and The Powers That MakeMKV/KEYDB need to know what they are before they can generate a database entry.

I see! Thanks for the help! Hopefully I'll be able to complete the rest of these disks.

I was just wondering, you wouldn't happen to know of a way to convert .m2ts ultra HD 4K videos into a different more accessible format that is lossless?

Ahem, I believe "MakeMKV" can "make .mkv files"... if that's what you're interested in...?

:shock:

would that maintain the ultra HD 4K quality? (how might I do that exactly? XD)
