ataraid and 1TB+ storage?

[Daniel Eriksson]

I can't seem to use ataraid to create a 1.2TB array from 6 x 200GB discs. If
I only use 5 of the discs it seems to work just fine. This is on CURRENT
from today.

Is this a known limitation?

All 6 discs are located on a HighPoint RocketRAID 454 controller.
