You'll never see this anyhow. Why did you click?
Seriously, putt a little thought into what is actually required to read data off of a hard drive that has been Properly overwritten. The parent's link makes the point that not only would the new random data obscure the deleted files, but the files written previously would do the same. If you're going to infer previous drive contents based on slight shifts in the magnetics of the drive, you have to realize that every use of the drive in the past has created the same shifts. Obviously there are areas that are more used than others but I would be perfectly happy with one complete overwrite of a drive that I'd been using for a few years previously.
Think of it this way: You can certainly track someone across a beach that few people have walked across, but if you expect that you can track me across Venice Beach a week after I go for a swim, you're nuts.
