Optical drives die or work intermittently, just like many other components. I have SCSI CD Writers going back to the 1990s, IDE and SATA DVD Writers from the 2000s, plus a bunch of Blu-ray writers. If one drive doesn't work properly, I try another drive in a different machine, then another....
HD or 4K UHD?
Is the drive re-flashed for LibreDrive and MakeMKV?
Do you have the latest firmware in the drive?
Unless you try a different Blu-ray drive in the same machine and the problematic Blu-ray drive in another computer, you cannot rule out the fact the drive (or SATA data/power cables) might be bad. Then there's the media itself to consider. Finally there's the OS and the software to check. Not easy with limited resources.
Could just be a coincidence. Failing to read discs, be they CD, DVD or Blu-ray, is what happens sometimes.
Probably a drive problem. Have you tried the media in a different drive? Have you cleaned the laser? It might be dusty.
I have two identical Blu-ray discs and both fail the rip process at exactly the same spot. Guess it's fault in the mastering process. Time to send them both back to Amazon.
