I've been trying to burn a Blu-Ray dual layer video disc. Twice, at the end of the burn, the drive is cycled, as expected, but then I get the error "Device Not Ready - No Reference Position Found" and the verify fails to start. (Full log is below.) The disc does verify successfully on its own, and I am able to play the disc in my BluRay player, but I'd still like to verify the disc with the source files and be 100% confident that the burn was succesful.
I am using the current (2.5.8.0) version of Imgburn.
I have burned BD DL discs succesfully before, but it might have been with an older version of Imgburn. I am using the same computer, same BD drive, and discs from the same batch as when it did work. I have also successfully burned and verified plenty of DVDs and single layer BDs.
I finally created an image from the files instead, and then burned the disc from the image. In that case, both the burn and the verify worked successfully. I also did a second verify of the disk against the image, and that completed with no errors as well.
Any idea what is going on? The fact that the error happened twice in a row, and that it has worked before, with the only thing different being the version of Imgburn, makes me suspect the program, but I am reluctant to try again (burning from files) because of the cost of the blank BD DL discs.
