Ultimate UHD Drives Flashing Guide Updated 2025

[Billycar11]

Just started ripping movies again since my physical collection has grown over the last 2 years and started adding to my server again. Not sure what has changed in the last 2 years, DVDs and Blu-Rays rip no problem but all of a sudden I can't rip any UHD movies, tried to rip movies I've already ripped and have on my server and they are also showing they are encrypted now and MakeMKV doesn't work now when it did before. I have my drive info here. Did I miss anything in the last 2 years? And also, the movies read and play in VLC no problem, just MakeMKV can't get past encryption which wasn't an issue before.

I updated the keydb.cfg file in the MakeMKV folder and that hasn't helped either. Any feedback would be appreciated as I'm sure it's something simple I'm overlooking.
