Mount CD/DVD problems


Looking for help (naturally) on something that has not been a problem in Solaris or Slack... however this is my first step into RedHat and I'm on v5.1.

CD/DVD ROM is identified as in /dev
lrwxrwxrwx 1 root root 4 Apr 21 2010 cdrom -> scd0
lrwxrwxrwx 1 root root 4 Apr 21 2010 cdrom-sr0 -> scd0
lrwxrwxrwx 1 root root 4 Apr 21 2010 dvd -> scd0
lrwxrwxrwx 1 root root 4 Apr 21 2010 dvd-sr0 -> scd0

/mnt lists:
drwxr-xr-x 2 root root 4096 Jan 5 2010 cdrom
drwxr-xr-x 2 root root 4096 Jan 5 2010 usbstick

I placed a DVD in the drive and ran:

[root_encrypt mnt]# mount -t iso9660 /dev/scd0 /mnt/cdrom

to receive:

mount: block device /dev/scd0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
missing codepage or other error
In some cases useful info is found in syslog - try
dmesg | tail or so

Without a DVD in the drive, it just fails miserable...

Am I just out to lunch on this? I'd still rate myself as *green* in the linux world, so any help would be much appreciated.

Thanks!

ISO 9660 is a CD file system.
try mounting it without -t iso9660, i.e.
Code:
mount /dev/scd0 /mnt/cdrom

Of course it does. That is expected behavior as you are mounting a filesystem and if there is DVD there is no filesystem.
If it is an iso9660 filesystem, you would also expect it to be mounted read-only and to get that message.
What's on the DVD, any filesystem, data?
