I was able to burn the same command on the exact same hardware and software setup after a reboot. This is the second time I hit this bug in about five burn times. I cannot make a pattern yet.
When it happens, the drive in question is locked by the kernel and still spinning when it happens. Only a cold reboot fixes this, "sudo reboot now" didn't help. This is highly annoying, wasting an empty DVD and having to reboot! hdparm also fails: % sudo hdparm -d 0 /dev/sr0 /dev/sr0: setting using_dma to 0 (off) HDIO_SET_DMA failed: Inappropriate ioctl for device HDIO_GET_DMA failed: Inappropriate ioctl for device % sudo hdparm /dev/sr0 /dev/sr0: multcount = 0 (off) IO_support = 0 (default) readonly = 0 (off) readahead = 256 (on) HDIO_GETGEO failed: Inappropriate ioctl for device -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/92383 Title: WRITE@LBA=288830h failed with SK=7h/ASC=00h/ACQ=00h]: Input/output error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dvd+rw-tools/+bug/92383/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
