Good one. People get more and more fancifully creative in the fictitious ways they concoct to suggest that any given magnetic storage device actually has infinite capacity.
Not ficticious at all to recover data this way, Randall. See http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html for just one of many references google finds.
Despite your assertions, I am not suggesting that any given magnetic device has an _infinite_ capacity. That'd be silly. ;-)
With the drive's internal r/w heads, the capacity is fixed. However, when you then read _all_ the data with a far more accurate and tiny read head (the microscope), you have access to data that the normal large head can't differentiate between.

You know what makes me Laugh about all this .. The simple fact they are SECOND HAND Hdd's just use dban a couple of times and they are safe enough to be resold for sure .. put it like this if someone was desperate enough for inside dirt on any of the companies these old hdd's belonged to then they would just drive a JCB thru the door and get what they wanted item no faffing about paying someone ripoff fees to gain what not a lot in all honestey (and yes i have used data recovery services several times they are not all they are cracked up to be) Now if they were truely of a Sensitive nature then the only way is total mechanical destruction then smelting for good measure but what a cost to hide the fact that someone had half a disc full of porno that seems to be the main thing people get there knickers in a not over what i the boss/wife finds i had porno on the drive well it's simple dont go there ..
