CDRom Drive Mounting Errors

I recently upgraded by Red Hat Linux
workstation from Red Hat 7.0 to Red Hat 7.1
and also upgraded Gnome to 1.4. Since that
time I can no longer mount my CDRom drive.
I keep getting the following error message:

“mount wrong fs type, badoption, bad
superblock on /dev/cdrom, or too many
mounted file systems (could this be the IDE
device where you in fact use ide-scsi so
that sr0 or sda or so is needed?)”

I do not have any SCSI cables or drives on
my workstation. What should I do?
