View Full Version : [SOLVED] Unable to mount cdrom0

November 14th, 2009, 04:00 PM
When I select the cdrom0 icon on my HP Pavilion ZX5000 running 9.10 I receive the following message:

mount: special device /dev/scd0 does not exist

I used the cdrom to install 9.10 and it worked on 7.10 and 8.04.

You could go to Administration --> Users and Groups and click on your user name and then go to Properties and check that the cdrom check box has a tick in it under the user privileges tab. If not, unlock the user settings at the unlock button via your password and check the box next to cdrom. The problem is quite possibly a permissions issue. If the cdrom is owned by root, you may have to modify ownership of the device. If that doesn't help, please post the output of
cat /etc/fstab

The CD ROM Drives box is checked in the Users and Groups administration window. Below is the content of fstab as suggested.


dale@dale-HP:~$ cat /etc/fstab

Hate to ask an obvious question, but is there a disk in the drive? My drives will only mount when I insert a disk into them.
(exception .. floppy drive on Mythbuntu PVR mounts on boot! ... no clue as to why!! Bios??)

sudo lshw -C disk
in a terminal.

if your cdrom is detected, the command should list the logical names:

description: DVD-RAM writer
product: DRW-1608P3S
vendor: ASUS
physical id: 0.0.0
bus info: scsi@4:0.0.0
logical name: /dev/cdrom
logical name: /dev/cdrom0
logical name: /dev/cdrw
logical name: /dev/cdrw0
logical name: /dev/dvd
logical name: /dev/dvd0
logical name: /dev/dvdrw
logical name: /dev/dvdrw0
logical name: /dev/scd0
logical name: /dev/sr0
version: 1.19
capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram
configuration: ansiversion=5 status=open

replace /dev/scd0 in fsatb with one of the names listed by lshw.

Thanks for the suggestions. I think it needed a disk in the drive. Seems to work now.

Hey. I'm having the same issue...I dont' want to hijack the original post, but I'm eager to see what the solution will be.
