Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I removed the reference to the second drive from fstab and rebooted.
The error/warning message persists.
However, immediately after re-boot I re-issued dmesg. Here's the relevent excerpt (lines numbers added for clarity):

163 Device not ready. Make sure there is a disc in the drive.
164 cdrom: This disc doesn't have any tracks I recognize!
165 Device not ready. Make sure there is a disc in the drive.
166 Device not ready. Make sure there is a disc in the drive.
167 Device not ready. Make sure there is a disc in the drive.
So is it complaining about one of the two CDROM drives? They both appear in Hardware Browser and I can successfully mount/read CDs in either drive.
