cdrom mounting problem

[fbgp2000]

I am a begineer in Linux. I have recently installed Fedora 8 and I am about to install my Network adapter. To do so, I need my CDROM. To mount my cdrom, I used the following command:

mount -t iso9660 -o ro /dev/cdrom /mnt/cdrom
(Because there was no folder named cdrom in mnt, I made one)
but it returns the followin error message:
mount: No medium found

The cdrom is installed as IDE Primary Slave

My fstab contains the bellow information:
/dev/VolGroup00/LogVol00 / ext3 defaults 1 1
LABEL=/boot /boot ext3 defaults 1 2
tmpfs /dev/shm tmpfs defaults 0 0
devpts /dev/pts devpts gid=5,mode=620 0 0
sysfs /sys sysfs defaults 0 0
proc /proc proc defaults 0 0
/dev/VolGroup00/LogVol01 swap swap defaults 0 0

Please help

1, is the disk in your cdrom ?
2, is directory /mnt/cddrom exist ?

Yes to both questions
1- My CD is in the CDROM
2- I have made the directory named cdrom inside mnt

Are you sure your CD Rom device is /dev/cdrom? (well it should be in fedora)
check If you got /dev/scd device first..
and use.

mount -t iso9660 -o ro /dev/scd0 /mnt/cdrom

Thank you for the reply.

I found the answer:

I used 2 different media of the same company (Both were drivers network adapter of D-Link DEF-530TX) But both were leading me to an error. Then I used another CD burned by another company (It was Ubunto) and with a lot of surprise, it worked! So I thought maybe the way the CDs were burned was important. Then I copied the contents of the other CDs to a computer with MS-Windows OS and then I burned them into another CD with "Roxio Create CD" software (That was the only burning tool on my laptop) then I used the new CD in Fedora. This time it worked properly.

Thank you all for answering.
