thats actually the way I am doing it, 80 gig main internal, then a 1tb 2nd internal.
Also I got my router issue fixed thanks to Collin, I used the reset button on my router, then flipped eth0 and eth1 on the admin website. Unfortunately I still get a kernel panic from the same MD that has never succesfully net booted. I might try to net boot a third MD to see if its the core or the MD then try and figure out a way to get it to work.
