There is a tool with a graphical interface called
PYSDM (PYthon Storage Device Manager).
PYSDM let's you configure the way your harddrives are handled by your system by just clicking boxes. It actually writes lines in fstab so it is good if you don't want to mess up with configuration files.
You can find it in synaptic.
After the installation you will find it under "system" menu, but I'm not sure.
Hope that helps
