Regarding my inquiry:
">" I am currently involved in the construction of a Sun-based information

">"Thanks for the assistance!

The majority opinion is that newfs(8) will do the trick, possibly proceeded by
some conflagration of the 'dd' command. However, Ray Smith mentioned the
*UniShred* software utility available from Los Altos Technologies. This
utility appears to meet DOD, NSA, NCSC guidelines. Information can be obtained
via e-mail from
