Ah, I see what you mean. OK then: a single overwrite with zeros will
make the data unrecoverable.

The data-recovery theory of the '80s and '90s was that the edge of the
old magnetic domains could be picked up with a microscope or some
other hypothetical sensitive instrument. That might have been
realistic when HDD tracks were millimetres wide, but now they fit
terabytes into the same size platters that used to hold hundreds of
megabytes, it's flat out impossible.

A single overwrite is definitely enough.
