Shouldn't matter, as long as your BIOS can boot it (which it obviously
can).

Okay, I haven't used the mdadm (I used raidtools2), but shouldn't this
be hdb1 missing?

and then shouldn't you have a working /dev/md0 to mkfs -t ext3 /dev/md0?

If above was incorrect, then hdb1 would be part of the (active) RAID? so
you can't import it again.
I haven't done that much RAID, and not with mdadm. But if my comments
above are correct, maybe this is your problem?
