For others googling this later, another very good reason for *never*
RAID'ing raw block devices (ie always creating at least one partition
first) is that if you ever mistakenly boot into some flavors of
Windows (even from some optical discs, perhaps unknowingly left ina
drive), your disks will automatically get "helpfully" initialized, as
windoze thinks it's a brand new empty drive being offered up like a
virgin for sacrifice - **poof** there goes all your data.
