I have been also looking around for an easy way for you too recover your data.
Can you supply some more information on the file formatt you used on the drives and if possible the controller on the terastation.
One vital bit of advice i can give at this point is it is essential for you to keep the volumes in order or at least identifiable, they have to be reinstalled as originally setup or the parody system and file structure will fail.
It is not essential to have them setup as a raid 5 to recover the data, you can do one disk at a time by rights and then work your way through all 4 drives. The important thing will be retrieving each disks information intact and uncorrupted and then making sure they are reinserted in order.
i will continue to pop in and see how things are progressing
