Well, mdadm --query fails because I didn't specify a device. Of
course, that is the whole problem. 

What I really need is a command to sync the two drives so they are
equal. I can't figure that out from the man page either. But if I can
figure out how to do it, then I can later just remove one drive (e.g.,
all the B drives) of each of the four partitions. Then I should be able
to use gparted to grow the 45 GB "A" boot and / drive by adding the
other A drives to it. 

I got the video on Karmic fixed (had two nVidia drivers installed that
were competing with each other), so fixing and undoing the RAID is my
current plan.
