I thought with RAID1 being "all drives identical," and that unless you
were using yet another drive to boot from (separate from your raid),
that each drive would have a boot partition on it.  Following that
train of thought, if your controller didn't let you boot from a
different drive (which seems a serious shortcoming, to me), wouldn't it
be possible to just unplug the drives and put your still working one
into the first slot?

Just a brute force and ignorance approach to the situation...

Seems to me that the idea of mirrored drives is to give an easy way of
dealing with drive failures, surely it shouldn't impose complex
routines to get past the first drive going bad.
