Hi all, i know this is an old question, but i really try all the methods in the forum, but still can't get my cdrom mounted, pls help!

FYI, i can mount the cdrom previously.
This is what i did for mount cdrom:

> mount -t auto /dev/scd0 /mnt/cdrom
/dev/scd0: Input/output error
mount: block device /dev/scd0 is write-protected, mounting read-only
/dev/scd0: Input/output error
mount: you must specify the filesystem type
> mount -t iso9660 /dev/scd0 /mnt/cdrom
mount: block device /dev/scd0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
or too many mounted file systems

This is the message when i type dmesg:
...

This is the message for lsmod:

So i think the scsi support is loaded, then why the cdrom cannot be mounted? Anyone?

What hardware? What cd-drom drive?

my CDrom/DVDrom: Imation DVD RW
OS version: RedHat Enterprise Linux V3 update 7.

Did you try mounting /dev/sr0 instead?

yes, i did, but unsucessful. It reply:
mount: special device /dev/sr0 does not exist

I've tried today for a data CD, and I can mount the CD with the command:
mount -t auto /dev/scd0 /mnt/cdrom

But I still can't mount audio CD. It display:
/dev/scd0: Input/output error
mount: block device /dev/scd0 is write-protected, mounting read-only
/dev/scd0: Input/output error
mount: you must specify the filesystem type

Sometime when I insert the audio CD, the CD-player pop up itself and start playing the audio, but i can't hear anything, even after I adjusted the volume. Then I realised that the audio is coming out from the cdrom audio jack output. How can I set to play the audio using computer's hardware?

And how to mount an audio CD in linux?

Can't see iso9660 in the list of modules, is it loaded?

I'm not sure whether iso9660 is loaded, but I can't find it in the list of lsmod. So, how can I load it if I don't?

modprobe iso9660

Tink

Hmm... This is what I get:
> /sbin/modprobe iso9660
modprobe: Can't locate module iso9660

So, it could be that I don't have this module or the iso9660 is built in?

If you run "cat /proc/filesystems" do you see iso9660 listed there?

yes, i can c iso9660 there.

Hmmm ... so it's compiled into the kernel... what type of media
are you trying to mount, did you try more than one CD?


Cheers,
Tink

Yes, i can mount data CD, but can't mount audio CD. So strange...

Not really, as you're not supposed to mount audio CDs.

Do the songs (CDDA) entries show up if you run k3b, and select disc info?
I don't believe that music cd's are mounted. The device itself is played.

One thing you might try is to enter "audiocd:" in the konqueror address bar. This will allow you to copy the wav files, and even access mp3, cda, ogg, or flac equivalents.
