The problem is when a known good CD-R is placed in the drive, it is not mounted automatically. However, if it is a bootable CD-R and you select the boot option of the BIOS it will function normally. Also, When a blank CD-R is inserted into the drive, it is mounted automatically, but disk creation software reports an erroneous amount of free space available. Such as 247 MB or 512 MB when the disk is a 700 MB disk. However, if you proceed to record to the disk, even with an ISO image greater than the supposed available capacity, it records just fine. Other disk types such as DVD, audio, small cd-r work fine. This only seems to affect the larger, full size cd-r's ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-22-generic 4.4.0-22.40 ProcVersionSignature: Ubuntu 4.4.0-22.40-generic 4.4.8 Uname: Linux 4.4.0-22-generic x86_64 ApportVersion: 2.20.1-0ubuntu2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: karl 1886 F.... pulseaudio /dev/snd/controlC0: karl 1886 F.... pulseaudio CurrentDesktop: Unity Date: Sun May 22 14:38:13 2016 GvfsMonitorLog: Monitoring events.
