Raid5 on n-1 disks is more like raid0....
Are you sure there? It seem to have come up as one 200GB device?
cookiemonster:~# cat /proc/mdstat
Personalities : [raid5]
md0 : active raid5 hdd1[1] hdc1[0]
195358336 blocks level 5, 64k chunk, algorithm 2 [2/2] [UU]
unused devices: <none>

What you can basically do is build a degraded array (using missing)
mdadm -Cv /dev/md0 -l1 -n3 /dev/hdc1 /dev/hdd1 missing
Wouldn't I want -l5?
It will be like having raid0 (in terms of security) but will let you
move your existing data onto it.
...which is what I want, cause the last 200GB is the one with the data
on.
