Seagate GoFlex Home running Arch Linux ARM from ext3 partition with ext3 NAS partition

After using the guide here to get the bootloader onto the GoFlex flash memory (it wipes the original boot sequence, so make sure you really want to do this—keep in mind it is great to do though!), I took the drive out of the casing and hooked it up directly to my linux machine (Linux Mint 14 Cinnamon) and wiped everything and made two partitions, one for linux and one for your data (this way you get almost all of the 3TB minus 4 GB for linux space). I did the following:
before I began, I downloaded the arch linux ARM files:  
wget http://archlinuxarm.org/os/ArchLinuxARM-armv5te-latest.tar.gz
sudo -s
parted /dev/sdj  (or whatever the device address is)
mklabel gpt
mkpart primary 1 4GB
mkpart primary 4GB -1 (-1 means fill the rest)
mke2fs -j /dev/sdj1 (gives partition ext3 format)
mke2fs -j /dev/sdj2 (if large partition, takes awhile)
mount /dev/sdj1 /media/alarm (you have to run mkdir /media/alarm if you don't have that folder
cp ArchLinuxARM-armv5te-latest.tar.gz /media/alarm/
tar -xvzf ArchLinuxARM-armv5te-latest.tar.gz
rm ArchLinuxARM-armv5te-latest.tar.gz
gdisk /dev/sdj
(follow guide below except for the type 0700 and 8300, i ignored that and still worked, don't even know what that is)
once followed, run pacman -Syu (upgrade system, answered yes to everything)
Problem step was adding UUID="theuuidforsda2" /media/NASdata ext3 defaults 0 0 to the fstab
On the next boot, I got a green light but no IP address to SSH to.

I installed gdisk then ran it. both partitions where type 0700 but the usb was 8300 so i used option 't' to change both partitions type code to 8300.

Then used option r for recovery and h for hybrid.

I put both partitions in the sequence, at 'Place EFI GPT partition first question I answered no. I used hex code 83 for both partitions giving the first the bootable flag and then answered no to the protect more patitions question. Then m for main menu and w to write.

Removed the usb and did reboot and the light flashed then went solid. ssh into the drive ok.

Check ensure system running

do a reboot (warm start):

shutdown -r now

and then later shutdown:

shutdown -h now

then power up (cold start)
