Well there are absolutely no visible blemishes on either disc but considering they fail at two completely different spots points to something on them the drives aren't liking.

Unless you have microscopic vision, how it "looks to you" is irrelevant. UHD's store up to 3x more data in the same space as a blu-ray. Meaning even at a microscopic level it can cause issues even if the disc "looks fine".

And yet I have UHD discs I've had for a few years that do have visible blemishes that have ripped fine. As a matter of fact out of all my years of ripping these two brand new discs are the only ones that won't rip.

I'm not arguing with you, obviously there is something wrong with the discs. I just think it's a little ridiculous that I happened to get two brand new discs and both won't rip. Or just some really bad luck.

Another FYI for anyone new to this, you'll always be able to do a full disc backup, even if the keys aren't known yet (no actual decryption takes place). This is precisely what I do when I get a "volume key unknown" error. Back it up, put away the disc forever, and check back in a few days.
This is also good as you can verify the disc itself is free of defects.

Based on this math, a standard BD stores 25 GB per layer, so you're saying they store upwards of 75 GB per layer? All along I thought it was 25GB vs 33GB, a 75% increase in density, not 300%. :mrgreen:

Well, I suppose quadruple layer discs aren't used for UHD so double the storage of BD. Still, the point stands that "I looked at the disc and it's clean" is a total bullshit method of looking for defects in a disc.

ANSWERED...

I was lazy.

Found out you decrypt so you don't have to run it through MakeMKV again.

Carry on...

Quick question... Oops, this is UHD forum and not bluray, but actually the question is still valid, I guess???

When backing up a full bluray until the proper playlist is known, does it really matter, at all, if you check or uncheck the "Decrypt video files"? Seems it doesn't know, yet, so that check has no effect.

How does that factor in?

Thank you,

Rick

Fails in exactly the same spot every time. Disc looks good. Please don't say I have a bad drive...

Edit: It was bad media.

A drive issue would tend to fail at DIFFERENT spots; the exact same point in a file points at an actual error on the disk at that point.

You were correct, it was bad media. It seems like sometimes I have to try and image a disc multiple times before a good run. Are bluray drives super sensitive to going bad? Imaging UHD seems very touchy compared to standard blueray movies.

I plan on picking up a different drive to try endgame. I’ve tried two different discs, cleaned the hell out of both of them(already brand new out of the box), tried full back up instead of making mkv, saving to usb drive......nothing works. The two disks error out at two different spots. One much farther along than the other. Only disc I’ve had issues with.
I had two Endgame UHD discs fail in on me as well. Verified with two different drives. Each disc failed in the same (different for each disc) each time I tested it. Cleaned the hell out of them, even with soap & water, but didn't resolve anything. To validate it wasn't just a rip issue, I put one in the xbox, as the failure was very early on, and noted it also had a bad glitch that it couldn't pass without pixilating, pausing and then skipping a few seconds.
Might have had a 3rd or more fail but Amazon wouldn't ship me any more replacements as they had raised the price back up. Not the highest quality initial set of discs..

Got the Best Buy steelbook and Target digipak. Tested the discs and all of them were fine. Reckon Amazon just got a bad batch.
