does not properly detect CD media capabilities

[Martin Pitt]

Binary package hint: udev

Just seen when debugging something else: When I insert a normal CD-RW, I get

ID_CDROM=1
ID_CDROM_CD_R=1
ID_CDROM_CD_RW=1
ID_CDROM_DVD=1
ID_CDROM_DVD_R=1
ID_CDROM_DVD_RW=1
ID_CDROM_DVD_PLUS_R=1
ID_CDROM_DVD_PLUS_RW=1
ID_CDROM_DVD_PLUS_R_DL=1
ID_CDROM_MRW=1
ID_CDROM_MRW_W=1
ID_CDROM_MEDIA=1
ID_CDROM_MEDIA_CD_RW=1

which is bogus. This also happens for other people, e. g. in bug 439137

Can you run the /lib/udev/cdrom_id binary against your CD drive?

[Martin Pitt (pitti)]

No medium in drive:

$ /lib/udev/cdrom_id /dev/sr0
ID_CDROM=1
ID_CDROM_CD_R=1
ID_CDROM_CD_RW=1
ID_CDROM_DVD=1
ID_CDROM_DVD_R=1
ID_CDROM_MRW=1
ID_CDROM_MRW_W=1

CD-RW in drive:
$ /lib/udev/cdrom_id /dev/sr0
ID_CDROM=1
ID_CDROM_CD_R=1
ID_CDROM_CD_RW=1
ID_CDROM_DVD=1
ID_CDROM_DVD_R=1
ID_CDROM_DVD_RW=1
ID_CDROM_DVD_PLUS_R=1
ID_CDROM_DVD_PLUS_RW=1
ID_CDROM_DVD_PLUS_R_DL=1
ID_CDROM_MEDIA=1
ID_CDROM_MEDIA_CD_RW=1
ID_CDROM_MEDIA_STATE=complete
ID_CDROM_MEDIA_SESSION_COUNT=1
ID_CDROM_MEDIA_TRACK_COUNT=1
ID_CDROM_MEDIA_TRACK_COUNT_DATA=1

4.7 GB DVD+RW in drive yields exactly the same result.

Sorry, this was a brain fart. ID_CDROM_* are the drive capabilities, ID_CDROM_MEDIA_* are the media capabilities.

When I have the DVD+RW, I correctly get

ID_CDROM_MEDIA_DVD_PLUS_RW=1

Sorry for the noise.
