/etc/fstab consolidates mounting information.

Each active line defines:

<file system> <mount point>   <type>  <options>  <dump> <pass>

For example:

/dev/scd0   /media/cdrom0   ISO9660     ro      1   1

device/partition name, then where you want it mounted, then the
type of filesystem.

If you have a single disk called /dev/sda, for instance, you
might see your external CD show up as /dev/sdb. If there's
already a /dev/sdb listed in the file, that will conflict.

Hope that helps.
