Verbatim 43888 won't read Bluerays after 2015

[Halinos]

I have a Verbatim 43888 and I’ve already flashed it. So far I haven’t had any problems with Blu-rays, but once the discs are newer than 2015, the drive no longer reads them. Both Windows and MakeMKV show that there’s no disc in the drive. I’ve already connected the drive through a USB hub with external power, but I’m really at a loss. Does anyone have an idea what the problem could be?

Better post the drive info as text, as the images seem to have problem showing up (at least for me).

Oh, of course. I just thought maybe I couldn’t see the image.

Btw do you know if all the discs "newer than 2015" are BD50 (dual layer) and all otherwise are BD25 (single layer)? Are your collections all regular BD (i.e. non-UHD/4K)? Or by "newer than 2015" you really mean UHD BD?

[Halinos]

The last Blu-ray it recognized was from 2015. Therefore, I came to that conclusion. But these are “normal” Blu-rays, not UHD. How can I tell whether they’re BD25 or BD50?

[tomty89]

Well sometimes it is mentioned on the cover, but maybe it's a less common thing for western / Hollywood releases.

P.S. btw do you mean like the disc(s) that were recognized can still be recognized after attempting to read some newer discs, or do you mean like after such attempts not even the old discs can be recognized?
