Many years ago, I wrote a simple utility that fills a raw disk with
a pseudo-random sequence and then verifies it.  This sort of tool
can be useful for detecting the presence of silent data corruption
(or disk address wraparound).

There has been a recent thread about various strange behaviours from
LSI controllers and it has been stated that (at least for the 2008)
the card firmware _must_ match the FreeBSD driver version.  See
