Good evening @Coopervid,
I stumbled upon this post as I am finding via research that this drive can read 4K UHD discs, but placing one inside the device results in No disc.
I see in this post that you are providing assistance with this. If you are still, I would appreciate any that you are willing to send my way.
Thank you!
