The content discussed how a research lab (maybe MIT or another large tech university) was able to recover data from a hard drive after over 50 formats (or it may have been data overwrites or even a combination of both) (I seem to remember the key number as 57 "deletion" operations). I think the article mentioned the use of a scanning electron microscope, magnetic force scanning, or something similar or more high-tech. This might have been published to a tech Web news site or a tech e-mail newsletter. I've searched for hours and I can't seem to locate it again.

Perhaps you mean:

http://www.cs.auckland.ac.nz/~pgut001/pubs/secure_del.html

where Peter discusses use of magnetic force microscopy and a
variation known as magnetic force scanning tunneling microscopy.
