    I run into people all the time who have been told over and over, that
    whatever is on the drive is always easily retrievable even after being
    erased with zero-fill, but that is not necessarily true. It all depends on
    how far one wants to go in order to prevent any possible chance of retrieval
    no matter how remote, but the reality is that even one pass of a good
    zero-fill program should destroy data to the point that it would take a
    specialist in computer forensics and data retrieval techniques using
    spcialized equipment and laboratory conditions to get *anything* back
    resembling the orginal data, and even then the results may be completely
    unusable. It would be beyond the capability of most commerical data
    retrieval firms, and most certainly beyond the reach of anyone using
    off-the-shelf data recovery software. Just because he wanted a multipass
    security wipe doesn't mean he has anything criminal on the drive, and he
    certainly need not justify his reasoning for wanting such a program. I
    routinely get customers who want personal financial info scrubbed from old
    system they are giving to friends family, etc. and have to be reassured that
    even a zero-fill is adequate for that need, because of the amount of
    misinformation they hear.
