I have tried on win11(25h2) and Mac (MacOS 26.1). Both are sending me the same error msg. I have tried different Blu-ray Discs. Some of them I successfully made a copy with my old Verbatim External Slimline Blu-ray Writer before but now I unable to do a backup on my new Asus SBW-06D5H-U.
I even tried to use different cables that the new external blu-ray writer provided ( USB-A to Micro-B or USB-C to Micro-B). They are all unable to copy Blu-ray Disc.
I have tried CDs. It works. But I didn't try DvD because I don't have one.
The Blu-ray disc I tried to copy can be played, and my media player application works fine, so I'm sure the disc isn't broken.
And the disc is just FHD disc
May I ask for help here?
