mdadm --assemble /dev/md0 <drives> results in:
"mdadm: error opening md0: no such file or directory"

so then I tried MAKEDEV md anyway; I got:
"udev active, devices will be created in /dev/.static/dev"

forging ahead, I did
mdadm --assemble /dev/.static/dev/md0 <drives>, and
"mdadm: no recognizable superblock on /dev/sda"
"mdadm: /dev/sda has no superblock - assembly aborted"

Sadly, I got the same "/dev/sd* has no superblock" regardless of which drive
I put first in the list.  So all 4 drives failed simultaneously?
