I previously had a working RAID 1 array. I think as a result of running grub-install /dev/sdb and grub-install /dev/sdc I somehow wiped my computer of md0 and md1.
I need to set them up again. When I try to create the md0 array, I am getting the following error.
/dev# mdadm --create /dev/md0 --level=1 --raid-devices=2 /dev/sda1 missing -f
mdadm: device /dev/sda1 not suitable for any style of array
It seems like Debian thinks the drive is already in an array but it's not.

That is a really weird partitioning. But the "not suitable for any style of array" seems to be associated with the partition still being in use by something. Maybe http://forums.gentoo.org/viewtopic-t-819610-start-0.html can guide you toward a solution.
