You have two hds and you want to access the second one but you
specifically want it in the Places section.

If you mount the drive it will automatically show up in the places menu.
You also already have permissions on the drive.

sudo mount -a will list the drive in /etc/fstab

You can copy anything you want over to the drive already. As for
achieving... there are command line programs like rsync which can do
that or gui apps you can install.
