What command are you using to try to mount it?  If your mount point is
/mnt/scd0 (it could be anything, even /mnt/foo if you wanted it to) and your
CD-RW device is /dev/scd0, you should be able to mount the CD with a command
resembling:

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

If you are using a GUI feature in your window manager to mount the CD (or
even if you're not), check /etc/fstab and make sure you've got a
sane-looking entry.  Mine looks like this:

# grep cdrw /etc/fstab
/dev/scd0		/mnt/cdrw		iso9660	noauto,owner,ro 0 0

Also check the properties of whatever GUI tool you're using to make sure it
is trying to access the right device, mount point, etc.

I believe that some (most?) CD players (e.g. kscd) use /dev/cdrom as the
playback device by default.  Make sure you either change this to whatever
device you are really using (e.g. /dev/scd0) or change the /dev/cdrom
symlink from whatever it's currently pointing to (probably /dev/hd?) to
point at your CD-RW device (e.g. rm /dev/cdrom && ln -s /dev/scd0
/dev/cdrom).  Also, don't forget to connect the audio cable from your CD-RW
to your sound card.  I did that once and it took me a while to figure out
why no sound was coming out when I played a CD.

Then you're doing something wrong.  :)

What are the error messages you're getting at boot?

Could be.  Or it could be that something is already mounted on that mount
point.  Or it could be that mount was unable to automatically determine the
fstype of your cdrw.

That looks right to me, but review the info in the CD-Writing HOWTO to be
sure.

Good luck,
