Any reputable wipe program with multiple over-writes in several patterns
will make the data unrecoverable by any normal means. How recoverable it
is beyond that - i.e by the best equipment in government labs is a matter or
widespread rumor and conjecture. Over my many years in the IT field I most
often saw it conjectured there is equipment which can recover data
overwritten as many as 7 times and was never able to corroborate that with
any authoritative information. The new rumor seems to now say 21 times.
That seems extremely unlikely, but the truth is that no one really knows.
Perhaps it's best to destroy a drive if there were data of critical
importance to national security and it was likely to end up in a
multi-million dollar government lab, but short of that it's overkill.
