[Bug 581925] Re: HL-DT-ST DVD-RAM GH22NP20: Does not recognize any CD

[jonie]

The problem lies definitely in  cdrom_id – it cannot tell a blank dvd+rw from a complete dvd+rw, it shows the media having TOC and a data session. 
The function cd_media_info in cdrom_id should provide additional check if cd_media_dvd_plus_rw is set and get cd_media_state in a different way I guess.
Problem persists with upstream version 158, there is merely some code cleaup in the function in question.
I tested different media brands, checked the issue on another computer with Matshita UJ-841S, the bug is still present.
The scsi errors in kernel are normal, system tries to mount "complete" dvd+rw as reported by udev and fails, thus this is no kernel problem.
I wonder if we should refile this bug against udev with a more specific description that relates just to dvd+rw
