BD-RE PIONEER BD-RW BDR-UD04 1.11

[Cuddy2977]

OK: I have a BD-RE PIONEER BD-RW BDR-UD04 reader/burner: that, up until now, has read 4k discs perfectly well

Except … ?

When I’ve tried copying the 4k disc in the recent Aliens box set, I get a lot of error message: either when trying to back the disc up, or trying to open it.

What IS happening … ?

(The disc spins as if it’s being read when I put it into the drive: and shows up on the desktop. Beyond that, I get errors.)

Wash the disc with warm water and liquid soap.

Would that work? Should it be needed?

The disc is *literally* fresh out of the package.

Try it. New discs very often have a film on it that is invisible but makes them hard to read. I pretty much wash all UHD discs before I rip them.

As an extra thought, and before I wash the thing in soapy water?

I’ve *just* tried backing the disc up, again: and, after a lot of ‘Scsi error - MEDIUM ERROR:L-EC UNCORRECTABLE ERROR’ warnings, been told ‘The volume key is unknown for this disc - video can’t be decrypted’

What the fornication is going on, and how do I stop it?

OK, Cheers, Coopervid.

I’ve tried that … and, when I put the blessed thing back in, it kept appearing and disappearing from the desktop!

And … ?

Now I’ve updated to Sequoia 15.4, there seems to be more problems!

I’m having a bad week!
