You should be glad you didn't. As someone nearing the end of a 2-month journey ripping thousands of blurays, it's sad to see how many simply no longer work. The material degrades and they become unrippable (or DRM prevents it? Or the reader doesn't work?). As you found, it's user-hostile territory and I suggest you avoid it. In my case, these were all legally collected so each one that doesn't work stings because that's about $40 that's gone forever.

I'd say maybe 10% haven't worked. Some have visibly blackened which I didn't realize was possible. Plus if you have 1tb of data to back up, you need 26 disks at the minimum!
