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). >Suspects: HW issues (memory, cables, MB, disks), driver issue >(not used mfi on tbolt 2208 based cards before). 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.
