DVD+R disc does not mount

Craig,

this looks like a duplicate of bug 44233. To be sure, and to solve your problem, can you try and change the cdrom line in fstab to:

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

Please let us know if that helps. If it does, the fix has been released in Gutsy and we are back on track for #1 ....

I have tried the suggested fix, with no luck. I edited the fstab and rebooted (although don't think that was necessary) and repeated the steps in the original bug description. I got almost the exact same results.

It shows the same error message in Gnome and I can still get to the files via the WinXP VM, however the log messages in the syslog are a bit different:

Sep 24 08:04:09 d620 NetworkManager: <debug info>^I[1190610249.826836] nm_hal_device_added (): New device added (hal udi is '/org/freedesktop/Hal/devices/volume_label_UDF_Volume').
Sep 24 08:04:12 d620 kernel: [ 241.156000] UDF-fs: No fileset found

Here is what my fstab file looks like now:
# /etc/fstab: static file system information.

Same bug here with Gutsy (just updated yesterday ;-) ).

I am trying to read a DVD-R

I also tried the workaround described by Albert with no success.

Also having a problem here with Gutsy

Trying to read a DVD+RW, fstab to show auto tried output of fstab and syslog when attempting to mount a burnt disc given below. Pre-pressed discs work fine. The icon for the drive in Nautilus disappears after the drive tries to read the disk.

I will be out of the office starting Thu 12/06/2007 and will not return
until Wed 08/20/2008.

I am not working in UNITAR anymore. Please contact Akiko Miyahara at

I seem to have solved this problem. It doesn't appear to be a bug as much as a configuration error, at least on my machine.

I noticed in a log file, following an X failure, that there was a message that "udftools" hadn't started as there were no suitable devices. Scouting around I found out that my optical device wasn't listed in /etc/default/udftools. Entering my device in the DEVICE="" line and then running "/etc/init.d/udftools" allows me to mount my previously packet written DVD+RW.

Will check but I believe that this should also work every time I startup

I went to try the suggested fix and found that udftools was not installed. I had done the standard/default install of Ubuntu 7.10 desktop and have performed all updates as they were released. This is all on same the machine listed in the initial bug report.

To test, I installed udftools and looked in the config file mentioned and as noted in the other comments, found that it contained no devices. I added my drive and restarted the service (sudo /etc/init.d/udftools restart) I didn’t see any errors on the screen or in the syslog so I assume there were no problems.

When I put in the DVD I have been testing with, I get the same problem though and it seems that udftools has not done much to help. My first guess would be that my drive is not supported but I really don’t know much about DVD drives and formats and such. Also it is suspicious that I am still able to run VirtualBox and read the same DVD from a WinXP virtual machine.

So for me this bug is exactly the same as when I opened it even with the change to Ubuntu 7.10 and the udftools installed.

Further discussion in bug 44233 seems to suggest that this may be due to the fact that your DVD was burned in multisession mode. Can you burn 2 test discs, one in multisession and one as a single session using Nero (Windows) or K3B (Linux) and test this? Thanks!

Thanks, I will do that as soon as possible, which may not be so soon
though. I am living in Tanzania (east Africa) and unfortunately it is
difficult for me to get discs to test with.

Same problem here. Put "auto" in fstab to replace "udf,iso9660",
installed and configured udftools, all without result.
Also tried to mount with -o ro,session=0, which gives a "no fileset found" in dmesg.
mount with -o ro,session=1 (2,3...) results in "no partition found (1)".

I'm in the exact same boat as you craig. I actually posted bug 240341 with the same problem because i didn't see yours. This is definitely confirmed though. I have more details in my report, but it seems the issue is not specific to all udf discs, Hardy Heron or even Ubuntu. It might have something to do with certain multisession modes, but i have no way to confirm that at the moment.

I have been having the same trouble with Feisty and DVD -Rs. I burned mpgs using K3B (default "burn"), but then I would get the "unable to mount volume" when reloading the newly made disk. Occasionally it would mount! but mostly it wouldn't. Tried the same disk on a different machine with Hardy, it would mount it, but would treat it as a new blank DVD. It was fine on an XP laptop and also my DVD player with the TV.

 I didn't try changing my fstab - since several people seemed to say it didn't have an effect. But after reading this page I tried the multisession suggestion.

 [In K3b, set up your project. press the "burn" button you then get a DVD Project Dialog box with various options. Go to the Misc tab where it says Multisession Mode, and drop down to the No Multisession option, then press Burn.]

When it had finished, it loaded fine and I could play the mpgs, also worked in Hardy. Hope this helps.

I do not currently have a Windows-burned, non-multisession disc to
test with, but perhaps this at least helps narrow down the bug.

I have this problem running Ubuntu 8.10 with a multi-session DVD+R burnt in CdBurnerXp (Windows XP).

I was trying to read my backups :-|

I can still read the DVD in windows XP.

This is one ugly bug.

Good luck, if you need any help, let me know.

I am having a similar issue with DVDs that I burned with Ubuntu. I am adding this note because it might be related.

DVDs that I burned with Ubuntu cannot be mounted. I have tested this with several blank DVD brands, multiple applications, and several computers (running Intrepid). The same DVDs are read normally in other devices (ie. PS3). Others in the Ubuntu forums have suggested that this may be a kernel config issue. However, I haven't been able to find any definitive fix.

I'm having the same problem with a data-dvd burned on Vista that 'm trying to open in Ubuntu 8.04.1. It opens up perfectly on Vista and XP, but no luck here so far. All the suggested workarounds do not work for me either. A solution would be appreciated!

I'm having the same trouble as outlined earlier by Craig, with one difference. I cannot read the file in Windows XP running in VirtualBox. I haven't tried any of the workarounds listed here yet.

Ubuntu 8.10 shows the disk as 'UDF Volume' when I click on it I get the following message "Invalid mount option when attempting to mount the volume 'UDF Volume'."

In WindowsXP (nearly vanilla install running in VirtualBox OSE) I get "D:\ is not accessible. The disk structure is corrupted and unreadable"

The disk is a DVD+R and was burned on Vista. I don't want to mention it to the person that burnt it, cos all the Windows bullies will laugh at me.

Ok, I don't know if this sheds any light on it, but I was able to read the same DVD using the same version of Ubuntu using a different DVD drive.

The computer that didn't work:
Dell 8200
Ubuntu 8.10
DVD drive is Dell DVD/CD burner combo drive bought with computer

The computer that did work:
Asus EeePC 1000
Ubuntu 8.10 with array.org kernel (not the lean one)
DVD drive is Emprex Dual Layer USB 2.0 Model No: 1016UI

I always though that USB drive was a bit pants, but I'm happy to be wrong! :)

Can you please retest this with a supported Ubuntu version? Thank you!

Seriously? Dude, this was from 2009. I don't even have those computers any
more, or the disc! Sorry, you can close the bug.
