Connie,

I found no (reasonably priced) utility when I looked at this about 2
years
ago. I was an Air Force contractor at the time and had much the same
problem
that you (probably) do.

My solution was to develop a Linux based solution to do this. The
advantage of
this was it supports both SCSI and IDE disks and doesn't care what
OS/Data is
on the disk.

There was also a document that dictated that for your needs you needed 3
passes
to "clear" the data and for more sensitive needs require 7 passes to
"sanitize"
the disk.

Many people that are familiar with disk technologies feel this may not
be
enough but to do anything with the data that may still be on the disk
requires
fairly expensive hardware and lots of time...
