You use --zero-superblock on the same thing which, when used with --examine, shows details of a raid array that you don't want. > Finally, I am using Superblock v1.0 here, but in reviewing the mdadm > thread archives, it seems that v1.2 is more commonly recommended.

If you are making a raid1 and might in some case want to mount just one of the devices without having md/raid in the way, then 1.0 is needed. If the partition is a logical volume that you might want to grow, then 1.1 or 1.2 is probably best. There are probably other situations where one is clearly better than another. I don't have a full list though.
