How to AutoMount a Second Drive

Hello all,

I have 2 hard drives on my computer; my master HD is 250GBs and the slave is 500GBs, SATA both HD. When I installed Hardy Heron LTS 8.04, I have disconnected the slave HD 500GBs when I installed the full system with apps, updates and everything that I need on the system based on my primary HD; when I finished setting up my computer on the master HD, then I plugged back again the slave hard drive and it shows on the Places -> Devices; also I can red all my docs, music and stuff that I have save on the second drive (slave 500GBs).

How I can mount the second drive automatically when the computer is booting and have the second drive as part of the main system?

I have tryied to do the following steps on this website, but didn't work properly for me:

My fstab looks like this
======================

======================

I would like to "automount" or load automatically as a part of the main system on my computer, like "C" and "D". at this moment I can access and read & write on the second drive without any inconvenience. Also when I open the second hard drive looks like is a removal media on the desktop and of course I can "unmount" the HD (500GBs).

Thank you for your support, best regards.
