First, update it to 6.5. Like, yesterday. 6.4 will contain things like the
heartbleed bug, etc.

You can either use the gui gparted, or the user hostile parted. Note that
if you do this, you'll probably have to reinstall - is that ok?
One other option would be to partition disk 0, say, into two 2GB
partitions, and RAID 1 them. Alternatively, what we're doing here for
drives 1TB and over is to make a root partition of 500GB, and the rest as
another partition.

will make you one big drive.
