Not sure if this is the best place to post, but I imagine plenty of ya’ll rip your discs either for backup or media server purposes. So I’m curious what you have found to work best / most reliably for ripping 4k discs, and if you have any tips for getting stubborn discs to rip well.
Personally I have an LG WH16NS40 internal drive and an LG BP60NB10 external drive, both flashed with Libredrive to allow 4k ripping, using MakeMKV. Generally they work pretty well, but I will occasionally get a stubborn disc (often from the library, sometimes even new) that just refuses to fully rip on either drive.
Lemon pledge and a microfiber cloth, followed by a microfiber lens wipe, clean up most grubby used discs. But you can only do so much if the disc is physically damaged.
So what’s in your toolkit?
I tried recovering a bad bluray with aaru, it was able to create a partial dump but I wasn’t able to fully read it. After about a week of churning it was still picking up more sectors but even if it might have gotten it in time I didn’t want to work my drive that hard.
I ended up finding a working copy of that movie at goodwill, but I still have other discs not reading. I decided it isn’t worth going beyond what you described, at some point the disc is just genuinely bad.
Never heard of aaru before, but I will check it out, thanks.
