So it should be there, but looking at your partitions, I don't see
/dev/sdd1 at all, which makes me go hmmm...
Can you please show the full and complete output from these two
commands?
sudo mdadm --examine /dev/sdc
sudo mdadm --examine /dev/sdc1
sudo mdadm --examine /dev/sdd
Did you maybe have LVM underneath, with MD on top? What does 'sudo pvs'
say? All of the above commands could be run as root too.

Bummers.

What is 'foremost'? I'm not familiar with this command. Ok, I see
it's a forensics program. It might be that you just got your
partition table(s) messed up on sdc and sdd, which will make things
harder. Esp since, as I noted before, you do NOT have a partition
table on /dev/sdd, which is surprising.

Where's the info for sdc and sdd?

Ouch! This isn't a great time. Can you do:

You should do this for all four disks, and all partitions on each of
the disks. Also, can you show:
cat /proc/partitions
as well. But maybe you setup hardware RAID on your old motherboard?
Can you provide more details on how you have the old one setup and
what model it was? Did you use the Intel software by any chance?
Do you have an 'lsdev' output from before the motherboard swap?
Good luck!

Yes, no sdd1 at all is odd. I've had other tools report issues with the
superblock, so I'm assuming it's related, and quite likely a partition
table issue :/
I definitely didn't have an LVM, I've been burned before using those and
prefer to do without :)
"sudo pvs" returns nothing.
You only asked for mdadm sda and sdb in your last reply, hence no sdc or
sdd (also I believe I may have included that in my original post?) Here
it is, regardless :)
