Well, no, until you boot from the hard drive you're just using the SD card to work on the hard drive. I'm not sure what automounting is happening on your machine, I usually turn it off. Booted from the SD, do cd /mnt. If that's an error you probably don't have one, so do cd / then mkdir /mnt.
Next you need to mount each of the 2 partitions on the hard drive to work on. First the DOS /boot partition mount /dev/sda1 /mnt then edit /mnt/boot/cmdline.txt which will become /boot/cmdline.txt then umount /mnt (cd out of it first if you're in it) and mount /dev/sda2 /mnt and edit /mnt/etc/fstab which will become your real fstab umount /mnt After that if you shut down and pull the SD it should boot from the hard drive. I've used my partition numbers because I don't know what yours are. Here sda1 is the DOS partition, sda2 is ext4, sda3 is swap.
