I have a server running Ubuntu 10.04 (it's on the other side of the world and I haven't built up the wherewithal to upgrade it remotely yet) and I have been told that there is a CD in one of it's two CD drives. I want to rip an image of the cd and then download it to my local computer (I don't need help with either of these steps).
However, I cannot seem to confirm whether or not there actually is a CD in the drive as I was told. It did not automatically mount anywhere (which I'm thinking might just be a result of it being a headless server not running X, nautilus, or any of the other nice user friendly things).
There are two CD drives connected via SCSI:
austin@austinvpn:/proc/scsi$ cat /proc/scsi/scsi
Attached devices:
Host: scsi0 Channel: 00 Id: 00 Lun: 00
Vendor: ATA Model: WDC WD400EB-75CP Rev: 06.0
Type: Direct-Access ANSI SCSI revision: 05
Host: scsi1 Channel: 00 Id: 00 Lun: 00
Vendor: Lite-On Model: LTN486S 48x Max Rev: YDS6
Type: CD-ROM ANSI SCSI revision: 05
Host: scsi1 Channel: 00 Id: 01 Lun: 00
Vendor: SAMSUNG Model: CD-R/RW SW-248F Rev: R602
Type: CD-ROM ANSI SCSI revision: 05
However when I try mounting either of these devices (and every other device that could possibly be the cd-drive), it says no medium found:
austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/scd1 /cdrom
mount: no medium found on /dev/sr1
austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/scd0 /cdrom
mount: no medium found on /dev/sr0
austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrom /cdrom
mount: no medium found on /dev/sr1
austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrom1 /cdrom
mount: no medium found on /dev/sr0
austin@austinvpn:/proc/scsi$ sudo mount -t iso9660 /dev/cdrw /cdrom
mount: no medium found on /dev/sr1
Here are the contents of my /dev folder:

And here is my fstab file:
austin@austinvpn:/proc/scsi$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name
# devices that works even if disks are added and removed. See fstab(5).
#
# <file system> <mount point> <type> <options> <dump> <pass>
proc /proc proc nodev,noexec,nosuid 0 0
/dev/mapper/austinvpn-root / ext4 errors=remount-ro 0 1
# /boot was on /dev/sda1 during installation
UUID=ed5520ae-c690-4ce6-881e-3598f299be06 /boot ext2 defaults 0 2
/dev/mapper/austinvpn-swap_1 none swap sw 0 0
Am I missing something/doing something wrong, or is there just no CD in the drive or is the drive possibly broken? Is there any nice command to list devices with mountable media?
Thanks in advance for any help!

The output isn't quite as pretty as yours but it doesn't require you to install anything:
