Specifically, run this command: mdadm --create --verbose --assume-clean /dev/md0 --level=5 --metadata=1.2 --chunk=128 --data-offset=262144 --raid-devices=4 /dev/sda1 /dev/sdb1 /dev/sdc1 missing The word missing replaces a device name, because the device doesn't exist. It doesn't say that the next device name is missing. > I'm tempted to subscribe to the mailing list, but I'm afraid of the > volume of e-mail I'm going to get.

The list isn't that busy, I would guess around 10 per day. You can always unsubscribe after you solve your problem, but staying subscribed will let you learn a lot about common issues, especially the drive timeout mismatch issues.
