How do I make a copy of a Blu-ray disc that my reader thinks that there is no disc

[BirdDad]

I have tried several different drives. I even resurfaced it.
I tried Blindwrite- it never saw it, same thing with ISO buster.
Could Clonezilla back it up sector by sector or is it just for hard disks and SSD's?
Thanks

Is it a genuine factory BRD? Does Clonezilla see it?

 

[BirdDad]

no it is videos of my family.

Is it an HTL, or LTH disc? (High-to-Low, aka "real" BD-R), or Low-to-High (aka DVD-like BD-R, cheaper and worse)?

Not all drives support LTH (although most modern ones should, I would think).

Are you certain that it was burned correctly? Did it ever play back, in any drive? Was it "verified" after burning?

Edit: If it was important, should have burned multiple copies, and verified all of them.

Oops, see that you have already tried ISOBuster. The only other program I know of like that is ISOPuzzle.
