I'm not an expert, but from my understanding of the theory, that challenge isn't offering anything like enough money. $500 is less than recovery companies charge for a normal recovery. I would have thought at least $10,000 is more like what you would need to offer, maybe more. You'd need something like a magnetic force microscope, and you'd need to read the disk at many times higher resolution than the data was initially recorded on it, so you'd need a large RAID array or something to store your intermediate data. And it would probably take many days to read. Once you've read the drive, you'll probably need to go through several rounds of writing some test data onto it and read it again in order to work out the pattern that the drive writes it's data in. Each of these will require even more massive amounts of time and storage. I suppose you may be able to skip this if you have sufficent documentation from the drive manufacturer, but I doubt it.
