First, I've read the recommended Q/As, so please don't mark this duplicate without a close reading.
I've installed Ubuntu 14.04 to the SSD, along with a swap partition. (there will not be any other OS at this time)
I'm looking at https://help.ubuntu.com/community/Partitioning/Home/Moving and getting ready to follow its recommendations.
I'm wondering if I need to start with step one of if I should use a subset of the instructions. I'm asking because when I boot the HDD already shows as mounted under media/
Should I start with "SETUP fstab" section since I already have the partitions? Do I even need that section since it appears it's already mounting at boot time? Should I go straight to "Copy /home to New Partition"?
