incrediBILL, since you worked in the industry, are you aware of any instance in which useful data was recovered from a hard disk which had been wiped by overwriting with random data?

Even if you could recover 7 bits of every byte, which would be pretty miraculous, this would not be enough to reconstruct anything useful.
