The problem is K3B is no longer ejecting and reloading the disc, ignoring whats set in preferences: you absolutely must eject the disc after burning on many drives, issuing any commands afterwards (such as trying to verify contents) will cause the drive to lock up.
You can fix this by running hdparm -w /dev/cdrom && hdparm -d1 /dev/cdrom, but it still breaks k3b's verify disc function. I am also suffering from this bug, and manually running genisoimage, wodim, eject, then eject -t then using md5sum or some other method to verify works, k3b is simply not ejecting the disc and reloading. IMO this is a critical bug. -- k3b: cdrom not recognized after burning https://bugs.launchpad.net/bugs/182114 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
