Ok I finally got it working. I did need to recompile my kernel and add:
device atapicam
Once I did that I ran:
growisofs -Z /dev/acd0c -R -J bkuptest
and I got an ioctl error. I then tried:
growisofs -Z /dev/cd0c -R -J bkuptest
and everything worked as it was supposed to. Thanks to Charles and
everyone else who pitched in their 2 cents.
