Isadora doesn't read DVD-R and DVD-RW

Bug Description

I have Isadora Main with some KDE applications including k3b. At first I thought it was a problem with k3b, but even when a DVD is seen as mounted in disc management utility (I'm not sure what is the original English name for it), Nautilus doesn't display its content. On two other forums people reported the same problem. And one wrote that it wasn't the case with Helena. Reinstalling dvd+rw-tools didn't help. I have to add that this doesn't concern all of my DVD-R. Some are read. But I'm sure that those which aren't read have no errors and they can be read on other systems, like windows or Mandriva. They can be even read on Virtualbox with Isadora as a host and Mandriva as as guest. I had to add that they were originally burn under windows.

I have same problem only with cdr and cdrw. It happens with brasero and k3b.Most are burnt on linux. I also get weired messages that say maybe the drive does not like the media.

The same topic on Ubuntu forums:

I upgraded my kernel to 2.6.34 and it helped a little but still I have to use pmount

Anyway, the problem still exist.

Hi axel,

This bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? Can you try with the latest development release of Ubuntu? ISO CD images are available from .

If it remains an issue, could you run the following command from a Terminal (Applications->Accessories->Terminal). It will automatically gather and attach updated debug information to this report.

apport-collect -p linux 600213

Also, if you could test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.

I am also facing the same problem. My DVD writer just refuses to mount any disk on Mint 9 Isadora. Disk utility says that no media is detected. However eject command works perfectly. The drive was working flawlessly just a few days ago before I updated the system. Upgrading the kernel didn't work. Please let me know if i need to post any reports with some hints as to how to generate these(I am a noob).

There must be something dodgy about mounting the DVD drive in LinuxMint 10 as well, both the Ubuntu version and the Debian version. Here's my story:
I downloaded and burned the Debian ISO successfully using K3b. Then, to be on the safe side, I burned three DVDs for backup, also using K3b, setting it to verify data after burn. Data passed the verification, so I went on to install the Debian issue from the DVD I did earlier. However, NONE of the backups I had made was mounted! I got a vague complaint about the DVD being write protected, and looking in the logs might give me a clue. The next day, my step son bought a laptop with Windows installed. I thought I could see if Windows is better at reading DVDs, and lo and behold! Windows could read all three backup disks without problems, and without complaining. Here's the relevant line in my fstab:
"/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto 0 0"
Going back to the Ubuntu heritage didn't help either. Just for the heck of it, I used Brasero to another backup disk, with the same result.
Also, using K3b or Brasero to try to append things onto the disks only results in the program asking you to insert an appendable disk. This implies to me that, somehow, for some reason, the system lies to the program.
Opening the Computer window shows the DVD drive as long as it is empty, but after inserting any of the backup disks, the DVD icon disappears. Apparently, it is trying to mount the disk, since it spins for a couple of seconds, but fails, for some reason.
Surely, the Linux community can not allow Windows to be better at anything, can it?
There is a program called DVDisaster, which can mount and read all three backups, so it is evidently not an impossible task.
