My Blu-ray drive suddenly can't read my blu ray disk. I inserted The Dark Knight, and it wouldn't read it. It would recognize that it is a BD-ROM, and (AnyDVD) recognized the correct size of the disk. It would read this before. But it would read and play the special feature disk, with is a single layer Blu-ray disk.
Who's fault is it? I don't have another Blu-ray to test it out with, nor I know anyone with a Blu-ray drive or player.
Unfortunately, that's the only way to eliminate either the player or your BD-ROM as the cause of your problem. Maybe a nearby computer shop has a Blu-ray drive which you can test your disk on?
