It could be that it is locked by another application.
What is the output of lsof /media/cdrom0 ?

shrikant@shrikant-desktop:~$ lsof /media/cdrom0
shrikant@shrikant-desktop:~$ lsof /media/cdrom0 ?
lsof: status error on ?: No such file or directory
shrikant@shrikant-desktop:~$ lsof /media/cdrom0
shrikant@shrikant-desktop:~$ lsof /media/cdrom0
shrikant@shrikant-desktop:~$

no output

¿Can you use the livecd on those cdrom drive?
If it didn't start, cdrom can be break.

yes... can use the live cd...

not a single cd playin...

even the mount cd option for the panel shows only option for mounting floppy...

please help....

as in.. cannot use the live cd...

but can use it to install ubuntu... when if i place it in drive n boot... but right now even if i put that inside.. it says no media in the drive...

Anything of relevance in dmesg?
Is it shown as recognised by udev (for instance ls -l /sys/block/scd0/)?
Check also that the link in /sys/block/scd0/ points to the right device.

If it's a music cd, like CD-audio , you can check if gnome-cd can reproduce it. If you ear strange noise, the cd-drive lens can be dirty, or simply, the drive has die.

Other things, probe to mount manually a normal data CD,
sudo mount -t iso9660 /dev/cdrom /media/cdrom

Anything of relevance in dmesg?
Is it shown as recognised by udev (for instance ls -l /sys/block/scd0/)?
Check also that the link in /sys/block/scd0/ points to the right device.

means should i type
 ls -l /sys/block/scd0/
in the terminal?

and tried mountin data cd... but cannot... have not tried the terminal though as me linux ignorant

type in terminal:

dmesg | grep scd

Take it and paste here.

shrikant@shrikant-desktop:~$ dmesg | grep scd

All this is abnormal.

what do i do???? please help.

You can revise internals cable connections , maybe the drive is break.

so its a hardware problem?? if i get a new drive will it be fine

it is like bug #10906...

but..

what do i do???

Hello !

Bug #10906 as been solved yet, so it can't be that (and it was a shtdown/reboot problem on LiveCD, nothing to do with you problem) ...

Can you check on another machine that your drive is still healthy ? If you have some Windows in dual boot, is the problem also present there ?

Regards,
Benoît

hi,
I might have some more and interesting infos on this subject for you. I encountered the same problem and posted about already here:
http://ubuntuforums.org/showthread.php?p=2706945#post2706945

This is a linux kernel bug. Maybe already fixed in a newer version than the one available with ubuntu.
