There was undoubtedly more than those two lines. I have no idea what might be happening from only those two lines.

Have you tried power cycling your optical drive?

After turning on that setting, when you start MakeMKV it should ask you which drive you want to lock that instance of MakeMKV to. Pick one of your drives, don't pick 'All drives'. To use a second drive, make a new instance of MakeMKV. Lock that instance to a different drive by picking a different dr...

Errors like this: Error 'Scsi error - MEDIUM ERROR:L-EC UNCORRECTABLE ERROR' occurred while reading '/BDMV/STREAM/00027.m2ts' at offset '389677056' mean that the drive was unable to correctly read a spot on the disc. The standard advice is to gently clean the disc and try again. A regular disc playe...

What does the MakeMKV log (the bottom part of the window) say when this happens?

Turn on 'Ask for single drive mode' on the IO tab in MakeMKV's preferences.

The output in the bottom half of the window when MakeMKV is ripping contains the log from the ripping process. Just copy and paste into a post here on the forum. If you want to be fancy, use the 'code' block in your post. https://forum.makemkv.com/forum/download/file.php?id=4980 If you have "Lo...

Need help on ripping fantastic4 I have no idea what the problem is. I do have the latest MKV. Just ripped a couple other UHD's fine.

Perhaps you could post the MakeMKV log from trying to rip your disc?

Please forgive me, I am not tech savvy at all. I downloaded the zip file posted but what do I do with it. I put the whole folder in .MakeMKV but that didn't get the program to read the disc. Again I apologize for my ignorance but any assistance would be appreciated. The file linked in the first pos...

This disc is being discussed elsewhere on this forum.

Thanks for the effort to help but since there's no way that the Android OS on my Sony TV could recognize,much less use, makeMKV to thereby decrypt my BD movies there's little point in going further. But I was told here that just using a BD drive with a pc to play DVDs and BDs will shorten its life....

Sorry, still learning the terminology. I mean cross-flashing Pioneer models that weren't originally UHD drives (e.g., XS05). As I understand it currently, the tools to cross flash a Pioneer drive are not currently public. I don't know if they'll ever be made public. MakeMKV's author, Mike, has stat...

There are two key distribution mechanisms that MakeMKV can use to decrypt 4K UHDs and AACS v82 blu-rays. The first is hashed keys and is built into MakeMKV. When you encounter either a 4K UHD or a AACS v82 disc that can't be decrypted, MakeMKV will automatically produce a dump file with a .tgz exten...

The drive is probably fine. Pioneer drives are considered the best, but they're hard to get since Pioneer is no longer in the optical drive business. If you do this long enough, you'll end up with multiple drives. In the Linux forum, there's lots of discussion about people having trouble flashing dr...
