Exactly; with disks these days it's pointless trying to second-guess
what's happening under the bonnet (ObUS: hood).
A well-known question in the security field, for instance, is how do you
know that you have *really* erased that disk? The thing can lie as much
as it likes, and you'll never know for sure.
