I would love a true reference (from the last 15 years). I have spent many hours looking into the question. The best I have seen is people claiming they can recover a bit here and bit there from modern drives. Not even any full bytes.
I have a NIST document that says labratory based recovery of data is impossible for disk drives 20GB or larger if the have been overwritten with a single pass of data. ie. Any data including all zeros.
That's not too surprising. All the new high-capacity drives use vertical recording and exploit giant magnetoresistance for reading. Thus there's much less magnetic energy associated with each bit recorded in these drives. If you could give a reference (or some rough identifying information) for that NIST paper, I'd be interested in looking at it.
