Ubuntu reads and burns DVDs but not CDs

Asked by Oliver

Hello, thanks for reading.

I've been having some troubles to read CDs with Ubuntu over the last distros, I don't yet know if it is a hardware or configuration problem or a bug. It has already been working, but I think it is back to before Dapper !

My DVD/CD drive is a NEC ND-3540A

* dmesg shows the DVD drive right :

[ 42.125353] scsi 0:0:0:0: CD-ROM _NEC DVD_RW ND-3540A 1.01 PQ: 0 ANSI: 5
[ 42.610800] Uniform CD-ROM driver Revision: 3.20
[ 42.610949] sr 0:0:0:0: Attached scsi CD-ROM sr0

* sudo lshw too :
(...)
           *-cdrom
                description: DVD writer
                product: DVD_RW ND-3540A
                vendor: _NEC
                physical id: 0.0.0
                bus info: scsi@0:0.0.0
                logical name: /dev/cdrom
                logical name: /dev/dvd
                logical name: /dev/scd0
                logical name: /dev/sr0
                version: 1.01
                serial: [_NEC DVD_RW ND-3540A 1.0105031600
                capabilities: removable audio cd-r cd-rw dvd dvd-r
                configuration: ansiversion=5 status=open
(...)

* my /etc/fstab is the following (only the CDROM stuff) :

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0

* when a CD (data, audio) is inserted, a mount /dev/cdrom gives :

~$ mount /dev/cdrom
mount: no medium found

* ~$ ls -lisa /dev/cdrom
9129 0 lrwxrwxrwx 1 root root 4 2007-09-15 17:06 /dev/cdrom -> scd0

* ~$ ls -lisa /dev/cdrw
9130 0 lrwxrwxrwx 1 root root 4 2007-09-15 17:06 /dev/cdrw -> scd0

* ~$ ls -lisa /dev/dvd
9131 0 lrwxrwxrwx 1 root root 4 2007-09-15 17:06 /dev/dvd -> scd0

* eject correctly ejects my drive

* When inserting a DVD, I can see in /etc/mtab :

/dev/scd0 /media/cdrom0 iso9660 ro,noexec,nosuid,nodev,user=daniel 0 0

* When ejecting then inserting an audio CD-ROM, I don't get anything in /etc/mtab. No new lines. Of course I tried to read the audio CD on my Gutsy Gibbon laptop with success.

Does anyone have a clue ? Because I don't !

When inserting a data CD/DVD to mount it you should type: mount /media/cdrom0

Audio CD is never mounted. It does not appear on mtab and this is expected behavior.

Try using sound-juicer to play the CD or another Audio CD player application.

Hello ClovisFabricio,

Thanks for your answer.

I tried to mount a data CD as proposed, but I got a no medium detected.
Launching sound-juicer does not work either, the Disk/Play-Pause are greyed, and the content does not appear.

Please insert a CD, and check for new lines in /var/log/messages and /var/log/syslog
Have you tried to use the CD another distro? Booting a live CD works? You could try booting a live CD distro that frees the CD after boot, so you can try using the drive on a live system.

Just some thoughts.

I had the opportunity to test the device on another PC, under Windows, and it showed the same problem : DVD are played and burnt OK, but not the CD. So I bought a new device and it works ok now.

Thanks for your help.
