Some RAID expertise would be very welcome!
     

I'm no expert... but I think you need to do the following:
mdadm --stop /dev/md127
mdadm --zero-superblock /dev/sd[a-c]
mdadm --create /dev/md0 --level=5 --raid-devices=3 /dev/sda1 /dev/sdb1 /dev/sdc1

All the best,

Maybe not, Tom, but you're clearly well on the way to becoming one!
Steps 1& 2 worked, but the create step failed because mdadm said it 
couldn't recognise /dev/sda1.
However a reboot later and it worked.
Thanks,
Graeme
