I'm not quite so unbelieving. I mean there are always ways to get at
data, hell,
you could just rip the drive out and take a hex image. But that isn't
the point.
There are software and hardware devices which can do this for you, and their
claim could be true to a certain extent.

There are a few other places to hide data: servo tracks, and tracks
where data about bad sectors are kept, but this sometimes requires
hardware to write to it.

Just my two cents on an interesting subject:)
