The system doesn't recognise and auto-mount cdrom when cd was burned in Windows.

In my Ubuntu /etc/fstab, I have :

/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

Try with utf8 (prehaps windows use unicode).

It didn't help.

# cdrom
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

Don't use scd0 but cdrom. We have not the same device.

Windows use a standard derived from iso9660, Joliet, but it is managed by Ubuntu (except if you disable it).

Could you try with a commercial CD (not burnt)?

The burnt CD which fails with 9.04 worked with previous version (try an old CD) ?

Try" sudo mount /media/cdrom0" to get a error message, and then "dmesg|tail".

Prehaps duplicate of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/106910, there were problem with CD at UDF standard.

> Don't use scd0 but cdrom. We have not the same device.
OK. Changed.
# cdrom
/dev/cdrom /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0
> Windows use a standard derived from iso9660, Joliet, but it is managed by Ubuntu (except if you disable it).
I haven't changed anything here. It fresh installation.
> Could you try with a commercial CD (not burnt)?
Yes, I already tried it. CD was not auto-mounted.
 > The burnt CD which fails with 9.04 worked with previous version (try an old CD) ?
Yes, I tried the same CDs on my other machine - Ubuntu 8.10, and it worked fine (CD was auto-mounted and pop up windows appeared - what I want to do with CD)

Hello, I am reading forum to learn how to investigate.

1++) CD standard identification
I am on Ubuntu 9.04 Jaunty and introduce a CD-ROM burned on W/XP.
Command mount return :

/dev/sr0 on /media/cdrom0 type iso9660 (ro,nosuid,nodev,utf8,user=delance)

What return mount on "other machine - Ubuntu 8.10" ? (I try to know which standard used Windows)
What softaware do you use to burn CD on Windows ?
Was it a CD or a DVD ? Was it multisession ? CD is data CD or audio CD ?

2) Try "mount -t iso9660 /dev/sr0 /media/cdrom0/".

3) Do "cat /proc/filesystems", and attach lines which contains udf or iso9660.

4) Device identification
Do "eject /dev/sr0" to validate the device name.
Is SATA or PATA (old IDE) ?
Is a CD reader, CD burner or a DVD reader&CD burner ?
In fstab, replace /dev/cdrom by /dev/sr0, but I am affraid it would change anything.
After reading forum, the fstab seems to be good.

I forgot to write that I am on 64bit (Kubuntu 9.04)
Toshiba Tecra A9 T9300

> What return mount on "other machine - Ubuntu 8.10" ? (I try to know which standard used Windows)
I'll past the output later.

> What software do you use to burn CD on Windows ?
If I remember it right, I used Nero on Windows XP Home

> Was it a CD or a DVD ? Was it multisession ? CD is data CD or audio CD ?
I tried several CDs (audio, data, vide). But what should be easy to reproduce: test original audio CD bought in music store. It should contains just songs in .wav format and was burned in Windows.

> 2) Try "mount -t iso9660 /dev/sr0 /media/cdrom0/"

# mount -t iso9660 /dev/sr0 /media/cdrom0/

On my computer, I get :

nodev sysfs

 udf
 iso9660

Your device identification is good, but I think you lack "driver" for windows file system UDF.
I will search more data on google ?
Can you confirm "cat /proc/filesystems" has iso9660 line but not udf ?

> Can you confirm "cat /proc/filesystems" has iso9660 line but not udf ?

yes, I can confirm that after "sudo mount -t iso9660 /dev/sr0 /media/cdrom0/" is no 'udf' in "/proc/filesystems"
just this:

nodev mqueue
        iso9660

If you do not need multi-sessions CD-R, you can on Window choose iso9660 instead of udf. Your burn software ask probably if you want multi-session (say No) or if you want to "close" the CD (say Yes).

But Linux kernel should read udf CD-R. And it is not an solution for your already burned CD-R.

I read on french ubuntu documentation that Vista do not use standard UDF, but I think it is now fixed in current kernel. Perhaps Roxio doesn't follow strictly the standard.

I never use multi-session, since there is CD-RW now. So I can not test if my computer recognize such CD.
I am more surprised that commercial CD works, since there should be iso9660.

The driver for "udf" is in kernel (I will change package associated in bug).

Do "lsmod | grep udf". Udf is managed by a kernel module and you should get :
udf 87716 0
crc_itu_t 10112 1 udf

Do a "sudo modprobe udf"

Try " sudo mount -t udf /dev/sr0 /media/cdrom0/"

Try "sudo mount /dev/sr0 /media/cdrom0 -t udf -o ro,user,noauto,exec,umask=0,session=0,lastblock=1"

Do also a "uname -rv" to get your kernel version.
Mine is "2.6.28-11-generic #42-Ubuntu SMP Fri Apr 17 01:57:59 UTC 2009"

I haven't used Windows for years. I'm not going to burn any CDs in Windows. I have discovered this bug when I tried to mount and play any commercial audio CD from music store.
Then I realised that it should affect also CDs burned in Windows. So I tried to mound some CD which I burned in Windows years ago. And with the same result.
This is not critical issue for me. But I believe, for other customers this should be fatal. If kernel doesn't contain 'udf' module as a default module.

I am on Ubuntu.
In Synaptic,
kernel 2.6.28-12 is today tagged "for test" (jaunty-proposed)
kernel 2.6.28-11 is today tagged "stable" (jaunty-update)

How you mean this?
Do you think that "stable" version is supporting udf in this case?

Yes.
I do not know how you get version 2.6.28-12,as in default configuration it is 2.6.28-11 which is supported.
Perhaps in Synaptic depot, you have added jaunty-proposed to use a software.
You should try to go back to 2.6.28-11 and wait the next "stable" kernel, by removing jaunty-proposed in your synaptic depot, if you have it.
Else we will try another solution.

I booted into 2.6.28-11

I found that DVD Video are on Udf format. And the DVD is mounted with any problem! And without udf kernel module.
If I do "modprobe udf", the DVD is also mounted.
