It may be the drive itself, its been a while but I've had them quit working for no reason and it has been after they haven't been used for a while.

Do you have a data CD actually loaded into the drive when you try to mount it? You can't mount an empty CD drive or an audio CD. What commands are you running when you try to mount?

What are you looking for in /dev

What kind of interface is it.

Cheers.

its a DVD-RW drive. in /boot it should show as "cdrom" but there is nothing. BIOS can see the device. if it helps, its IDE

What /dev/hd* devices do you see. And how many hard drives do you have.

Cheers.

Astol you didn't answer J.W.s question - if its an image (distro) or audio cd or dvd it won't show.

Cheers.

You may simply be mounting incorrectly. Bear in mind that a few things have changed since the unified libata driver was introduced. Many cd/dvd drives are now designated by scd instead of hd. Of course, if you're still using a 2.6.20- kernel, that wouldn't be the case.

I ran into a similar issue a few months ago and was able to find the correct device by running the lshw command (which, I believe, needs to be installed first).
