Well, I do, and did. I've been involved with the 380 chip set way back, and
I do know a bit about how it and hard drives in general work. And while
I've
not personally done it, I AM aware of the technologies involved, the theory
behind the technologies, and the practice implementing those technologies.
Granted, I've not heard much about the techniques since drives moved into
the ZBR (a LOT changed when drives went that route) world with the high
speed transfers (compared to early MFM), but there's nothing in the
techniques or theory that would make it impossible other than that the
tools and techniques have to stay 'ahead of the game' the same way they
were then.
It's doable. Period!
I'll give you one hint... Writing a 0 or a 1 DOESN'T totally erase what is
under it. Can you understand that? All writing a 0 or a 1 does is put
(actually,
'TRY' to put ) flux transitions down on the media at specific points. Or
try to.
Data already down on the media will influence where those transitions
actually
end up being detected on readback (digital), or distortions in the signal
(analog) ...
I'm through arguing with someone who obviously doesn't know what they are
talking about. You just cannot prove something doesn't exist or that
something
is impossible. You're putting yourself in the same reference frame as
people
who said manned piloted aircraft will never exceed the speed of sound. Or
that rockets just couldn't carry enough fuel in a 'step rocket'
(multi-stage)
to make it to the moon. In both cases, relatively simple technology
advances
led to the solution to the problem. You just can't understand that the
technology you see and touch is not the only technology that may exist.
