Thats interesting...I can do that without switching to root. Try looking
at the output of the id command.
I have a sneaking suspicion that is that you dont have permission to
read and write to your CD device. I dont want to hand out the answer to
a good practice problem like this one, so here's your homework ;o)
Check the permissions of the device representing your CD-RW drive and
decide what you will have to do to give yourself access to the device.
Hint: you shouldnt have to modify the permissions of the device itself.

I think you've got the wrong idea of what /etc/fstab is for. Take a look
at man mount, man fstab.
