A little too much other info, and overly eloquent. However, if your
company told the client that you were going to deGauss all the h/d, that's
what you need to do, contractually.
If they've had a second discussion, and only want the data deleted, that's
another story.
Is the data on a different partition than the o/s (i.e., /data? If so, you
can easily wipe the data, using say, shred, or DBAN (which offers both
3-pass and the full 7-pass DoD 5220.22-M). If it's in the same partition,
and the same filesystem, you've got other issues. How do you *guarantee*
that there's no user data - say, installed third-party software mixed with
the o/s?
Note that you really do have to make any third-party software, if it's
commercial, Go Away.
