    No you misunderstand. There are two species of problem

    1. 3 of 4 drives from two vendors that don't do UDMA right and
    corrupt stuff

    2. An undefined number of unpredictable circumstances where UDMA
    CRC will avoid other corruption caused by poor hardware/cabling

    So you only want to disable UDMA for #1. Disabling it globally by default
    will harm other people, and not to a predictible pattern. Hence the current
    solution is far from optimal
