UDEV [1240402978.959576] change /devices/pci0000:00/0000:00:1f.2/host1/target1:0:0/1:0:0:0/block/sr1 (block)
ACTION=change

ID_CDROM=1
ID_CDROM_DVD=1
ID_CDROM_MEDIA=1
ID_CDROM_MEDIA_DVD=1
ID_CDROM_MEDIA_STATE=blank
ID_CDROM_MEDIA_SESSION_NEXT=46336
ID_CDROM_MEDIA_SESSION_COUNT=33024
ID_CDROM_MEDIA_TRACK_COUNT=58368
