Someone with a similar issue sent us his solution:
I have had a similar problem as you except I just forgot to plug the power cord back in on one of my drives that was partitioned to be half virtual raid 1 and the rest a normal volume. After some messing around and googling to no avail, I realized in the "create and format hard drive partitions" utility there was a new block on the left with no drive information separate from the failed portions. All I needed to do to fix the issue was to click it and go through and add the failed partition to it. Now everything is back to normal. Hope this helps anyone who finds themself in a similar situation."
Thanks for your time and ill trust you will forward this on if you feel it would best serve the interests of planet earth
