Unable to mount CDROM

Thanks for your feedback.

I inserted a RHEL4 CD into the drive tried running the #mount /media/cdrom# command but the drive didn't seem to recognise the media.

#[root@localhost ~]# mount /media/cdrom0
mount: no medium found on /dev/sr0#

I tried another CDROM but got the same message. I then run the following commands:

#[root@localhost ~]# dmesg | grep sr0
sr0: scsi3-mmc drive: 1x/1x writer dvd-ram cd/rw xa/form2 cdda tray
sr 2:0:0:0: Attached scsi CD-ROM sr0
[root@localhost ~]# 
#[root@localhost ~]# ls -al /dev/sr0
brw-rw----+ 1 root cdrom 11, 0 Oct 23 08:13 /dev/sr0
[root@localhost ~]# ls -al /dev/cdrom0
ls: cannot access /dev/cdrom0: No such file or directory
[root@localhost ~]# ls -al /dev/cdrom1
lrwxrwxrwx. 1 root root 3 Oct 23 08:13 /dev/cdrom1 -> sr0
[root@localhost ~]#

Can you suggest anything else?.
