The link you posted goes to a FW400 enclosure, not a FW800 enclosure.
Assuming that was just a mistaken link, I'll start by saying that striping two drives together is not rocket science, and setting to "striped array" is correct, so it should work. Have you tried simply using the erase feature in Disk Utility since striping the two drives together? If not, try it, then test again.
Meanwhile, just by looking at that enclosure I can tell you the following: a) it's comprised of the cheapest components available; b) it's a very old design, so it's been sitting on the shelf a long time; c) I think you got what you paid for.
However, that being said, software RAIDs are so simple that it should work without much tinkering, so if it continues to be problematic you know you most likely have received defective hardware. To verify, put one drive in at a time and format each separately as a single drive and test both channels (sides) of the enclosure with both drives alone. This should help you to isolate the problem.
Got the idea?
