Cannot mount cdrom

Hi,

I can't mount a CDROM. DVDs are working fine. Here is the output of dmesg:

Re: Cannot mount cdrom

I have the same problem, the dmesg output eventually ends with a segfault:

Re: Cannot mount cdrom

Same problem here, I got the error from dmesg when trying to mount a CD.

Is there a way to mount the CD??

Re: Cannot mount cdrom

Something that I discovered while testing different CDs.
Thunar recognises CD if they are bootable CDs. For example my Arch, Ubuntu and Windows CD are read without problem.
The CD is recognised is I open it with Rhytmhbox, but the music files are on gray, they cannot be read.

Other things that I can do with the CDs
I can create an ISO image with brasero (audio and data CD)
I can play music files from VLC

What could the solution be?

Re: Cannot mount cdrom

I think this i related to the problem described here: http://bugs.archlinux.org/task/18119.

You could try mount the media with the filesystem-switch '-t iso9660'. If this works you can apply this patch (http://git.kernel.org/?p=utils/util-lin … 3674eb30fc) on the package 'util-linux-ng-2.17'.

Re: Cannot mount cdrom

Thanks Matzo, it seems that is my problem.

How do I apply the patch? I dont know how to use it or what to do with it.

Re: Cannot mount cdrom

Hi FerBenzaa,

I modified the PKGBUILD from the ABS and created a compressed file which also includes the mentioned patch. You can download this package at http://www.file-upload.net/download-227 … ar.gz.html. Simply unzip and run '[wiki]makepkg[/wiki]' in that directory.
Another possibility is a downgrade to util-linux-ng-2.16.2-1. This should also resolve that problem.

I hope this helps you somehow...

Re: Cannot mount cdrom

@matzo

Thanks for the patch. The downgrade didn't help the laptop out in the least; was still unable to read either cds or dvds. However your patch did work  to the extent that i am now able to automount cds but not dvds. However I can manually mount dvds now while before I would get the 'segmentation' error.

The problem also seems to be intermittent which makes it even harder to track, I suppose. Earlier I had used the down grade approach on the desktop and everything worked fine. Automounting worked for both cds and dvds however later dvds would not automount. But I could still manually mount them.

So, better than it was but there is still something wrong someplace. It also takes an eternity to manually mount a dvd. Later I'm going to try the patched file on the desktop but I need a break from this problem for awhile.

Re: Cannot mount cdrom

I also experiences some problems mounting disks. Keep getting some buffer errors, etc.

Please take a look into this developers.

Re: Cannot mount cdrom

Hi, I'm having the same problems.

If Thunar is working, some of the CD/DVDs are automounted and their directories are created by hal in /media and removed after an umount. But some of the discs won't be read. I have used wodim -v /dev/cdrw fedora.iso to burn a LiveCD of Fedora 12, this won't get recognized by thunar, but Ubuntu live, and some other data CD-s/ DVDs get recognized.

What is the problem? Anyone had some luck?

This is freaking weird: I put a normal data CD in the tray, and ls the /media for a while, nothing happens... nothing gets mounted but I can hear the CD device running normaly (no funny noises). I turn on Thunar, and within Thunar in the filesystem tree I get a directory with the CD label. Then I check the /media and there it is, the same directory!

Has anyone solved this?
