That's not usual. I have a BH16NS40 in a USB box from DeLOCK. No problems to open it with any medium. In general it is strange that open(2) or openat(2) make a difference between BD and DVD media. At that time the computer has no clue what's in the drive. It might be about using option O_NDELAY. In libburn's source code i have this comment from 2007: Switched to O_NDELAY for LKML statement 2007/4/11/141 by Alan Cox: "open() has side effects. The CD layer allows you to open with O_NDELAY if you want to avoid them." (IIRC it was about accessing a drive that is busy with burning and takes offense already from open(2).) What program do you use for ripping ? If not yet dd, what do you get from this: image_file=...path.where.to.store.data... dd if=/dev/sr0 bs=1M of="$image_file" or dd if=/dev/sr0 bs=1M iflag=nonblock of="$image_file" What would a burn program say about the DVD ? E.g. one of these runs: dvd+rw-mediainfo /dev/sr0 xorriso -outdev /dev/sr0 -toc Have a nice day :) Thomas _______________________________________________ users mailing list -- users@lists.fedoraproject.org To unsubscribe send an email to users-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@lists.fedoraproject.org
