If you are right, that means the message I sent back in October about how 
to do the RAID1 did not work for me.  It would also mean that the RAID1 
that Brian set up for me back in November 2008 has also not been working 
at all for the past 3+ years (see below).

I really need to do this right next time.  I'm about to setup another one 
of these software RAID1s on Ubuntu and I want to be sure it is done right.
