Please provide evidence that anyone has ever done this on a modern
drive.
Jumping into that discussion, here is evidence that this is not possible
with modern drives:

So, anyone who wants to sell his hard disk can just use

Don't believe everything you read on the internet. This guy may claim
to be a forensics expert, and he may claim to be able to do certain

wouldn't be able to discuss it), and he obviously does not have access
to some of the equipment available to others.
