The rip succeeded with a new LG blu-ray drive. My guess is that WarnerBros has figured out a way to keep older blu-ray drives from reading their discs. In tin-hat mode: I'd guess that they are deliberately hammering the drives with enough DRM crap to destroy the drives, requiring new drive purchases...

Well, I was an idiot. I swapped the subdirectory and drive names, so OF COURSE it couldn't write anything to a non-existent hard drive! :-P It would be really nice if MakeMKV would spit out more meaningful error messages, though. How hard is it to recognize "that drive doesn't exist"??? An...

Same here. I'm trying disc-backup.

In the continuing saga... So, it looks like my BD drive (Plextor PX-B310U) does not read this new crop of discs marked "RENTAL" at the bottom (I think they have all been WarnerBros. discs too). I just went through about 25 disc changes, hoping that maybe the drive would read the disc and r...

Belay that! WTF??? So, despite this being a *brand new* disc, rubbing it on my shirt and actually scratching it up a bit causes it to be readable. Huh?? Or, is this a problem with MakeMKV not working on first mount, but working after a second try? All I can do here is tell you exactly what I did to ...

It looks like a *manufacturing* error. I've now tried two or three different copies of this disc and none of them work. The latest one won't even show up in MakeMKV! I get "loading disc" and then: Type: no disc. I even power-cycled the drive, restarted MakeMKV (ensuring that makemkvcon was...

I see it, and after washing the disc with hot water and detergent, then restarting MakeMKV the "disc backup" icon is active! I'll give that a try now. Thanks! I should re-try the standard MKV rip too, to rule out the washing vs. "disc backup" as the solution here. EDIT: however, ...

Being unable to find a "full disc backup" option that isn't greyed out, I tried Stream. That works up until the unreadable sector, and then freezes. Interestingly, the error is different: DBG ASSERT: NG6.jZL7VPpr-.#_-Hv#1R@h%Ad5 at }IBH2[ROzN~F|LeM:29399335 EDIT: followed several minutes l...

Is there some way to set a switch in MakeMKV to "just go ahead and rip as much as you can and pad the bad bits, so I can at least watch this disc I just paid for!"? I thought that was what "rip full disc" was for, but I'm no longer finding that in any menu options.

I suppose it could be a bad drive too... Odd that it would only manifest on *specific* discs though. On the other hand, the second attempt at ripping this same disc resulted in *different* sectors, albeit from the same file, failing to read, yet still only three errors: Error 'Scsi error - MEDIUM ER...

Thanks for explaining the possible causes, in more detail than I've heard before. I guess the micro-fine scratch is causing the disc to be unreadable. Sad that blu-ray is such a fiddly medium that a tiny tiny scratch, on an otherwise perfect disc, causes a catastrophic read failure.

All tracks except the main title rip just fine. Here's the log from the failed main title rip.

That's exactly what I did (at least on several of my attempts). A typical exercise: turn off blu-ray drive, turn on blu-ray drive, start up MakeMKV, insert blu-ray, use MakeMKV to eject blu-ray, re-insert blu-ray, use MakeMKV to eject blu-ray, quit MakeMKV, turn blu-ray drive back on, start MakeMKV....

You may be right... however, this disc mounted and played as WB wanted it to (with 30min of unskippable previews) in a PS3. And *every* other blu-ray disc I tried in my Plextor drive mounted just fine, even my freakishly weird Euro blu-rays. I wouldn't put it past WB to have some new crap on their b...

1.7.0 ripped it!
