[SOLVED] Mounting Burned CD

CincinnatiKid · 08-07-2010, 06:49 PM

I am on Slackware 13.1 x86_64, Linux 2.6.33.4. I can mount most CD's fine, but here is what happens when I try to mount a burned cd.

Code:

bash-4.1$ mount /mnt/cdrom
mount: /dev/sr0: can't read superblock

I can mount the same CD on my Debian and Ubuntu installations. Since this works on different distro's, it seems like maybe there would be a fix. Does anyone have any ideas.

Here is my /etc/fstab just in case it will help:

Code:

bash-4.1$ cat /etc/fstab
/dev/sda1        swap             swap        defaults         0   0
/dev/sda2        /                ext3        defaults         1   1
/dev/cdrom      /mnt/cdrom       auto        noauto,owner,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,owner     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
tmpfs            /dev/shm         tmpfs       defaults         0   0

Using 'auto' as the filesystem type does not always work; it's fine for FAT file systems, but *might* not work reliably for other file systems. Try your mount command again, but specify a filesystem.

Incidentally, what's the burned CD contain? Like, is it an OS, data, an audio disc...?

EDIT - it's probably ISO9660 or UDF

It is an audio CD. I changed the type to iso9660. here is the output now.

Code:

root@david-slackware:~# mount /mnt/cdrom/
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

end_request: I/O error, dev sr0, sector 64
isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16

Tried udf also with the same result.

Just found this link that says Music CD's are not iso9660: http://www.linuxconfig.org/HowTo_mount_cdrom_in_linux. But it really doesn't give a solution. I will keep looking.

GrapefruiTgirl · 08-07-2010, 07:13 PM

What do you get from this (from that link you gave):

Code:

# cat /proc/filesystems

You cannot mount an audio CD -- there is no filesystem on it. Other distros may use tools that make it appear as though an audio CD is being mounted, but it isn't actually. I don't know about KDE4 but in KDE3.5 Konqeuror could pseudomount audio CDs using kioslaves to make it look as though there were mp3/ogg/etc. files on the disc. There may be some similar functionality in KDE4 and certainly in Gnome, but you will not be able to mount an audio CD through the command-line.

GrapefruiTgirl · 08-07-2010, 07:16 PM

Something worth mention too: while it doesn't address why you can't mount it, technically you should not need to actually mount it, in order to play it with some music CD playing software.

EDIT: T3slider said it right there above

- there's the issue.

Everything I am reading says Linux can't mount audio CD's. Like I said in Debian Gnome the CD auto mounts. These CD's are sermons at the church I go to, and I have a project where I am converting them to MP3 and uploading them to our church website. What I do in Debian is move the *.wav tracks to the hard disk, and then run sox to make 1 *.wav file with all of the tracks, then I run lame on it to convert it to mp3.

In my post above this one I explained kind of what I need to do, and how I used to do it in Debian. Do you have a suggestion on what I should do? Do you know any tools to put all the tracks in 1 file and encode it to mp3 format?

GrapefruiTgirl · 08-07-2010, 07:31 PM

For the record, I do not - I don't do much with audio CD's or audio in general. Hopefully T3 or someone else will have an idea.

T3slider · 08-07-2010, 07:48 PM

I don't use KDE4 so I don't know if dolphin and/or Konqueror can be made to 'mount' audio CDs as in Gnome and KDE3.5...it probably can be done but I have no instructions for you since I haven't tried. kaudiocreator is a good app for ripping CDs and is included with KDE4, so you may wish to try that (it is not drag-and-drop but it won't need any intermediate steps if you set it up properly). Someone else probably knows a lot more about KDE4 than I do...

CincinnatiKid · 08-08-2010, 08:29 AM

kaudiocreator worked great. Once I extracted the tracks, I just used sox to combine them and then lame to encode them as mp3. Thanks for your help T3slider.
