This refers to the fact that the device does not contain an ISO-9660
formatted media.

No.

The "device is configured" via the /etc/fstab file that controls how to
mount the disc, e. g.

	# Device        Mountpoint              FStype  Options         Dump    Pass#
	# -----------   ---------------------   ------  -------------   -----   -----
	/dev/acd0       /cdrom                  cd9660  ro,noauto       0       0

This will "expand" your command

	% mount /cdrom

to something like

	% mount -t cd9660 -o ro /dev/acd0 /cdrom

Also, keep in mind the permissions: You need +r for the device, and you
have to be the owner of the mount target directory. Furthermore, users
must be allowed to mount media which is controlled by the setting

	vfs.usermount=1

that is to be put into /etc/sysctl.conf.



But as I mentioned before, you cannot mount an audio CD; imagine that
it's "technically" impossible. :-)

(Of course, this says nothing about that you cannot copy audio tracks,
convert them into OGG/Vorbis or duplicate discs 1:1, which is ALL
possible.)



A final note: I see you're using /dev/cd0 for your CD drive. What about
using acd0 instead (if it's an ATAPI drive)? You can specify /dev/cd0
as $CDROM if you've got a SCSI device, but then, due to permissions,
I think you need to set proper access rules for the xpt device, too.
