 1. NSA claims that it can recover data from residual magnetic
    fields; I have no way of cerifying that, but they have more
    experise than either of us.

 2. While on old DASD Write CKD actually erases data, that need not
    be true on newer DASD. Was your statement specific to the 2105
    or intended to be general?
