maximum Maytag mode
     
         (From the US brand of washing machine) What
        a {washing machine} or, by extension, any {hard disk} is in
        when it's being used so heavily that it's shaking like an old
        Maytag with an unbalanced load.  If prolonged for any length
        of time, can lead to disks becoming {walking drives}.
