Yes, it can be done.. it would cost about 100k per drive and the ability to access an electron scanning microscope. At 30 times I highly doubt they could recover anything of any value anyway. Using most commercially available products like "Encase", you can recover files that have been deleted, but not overwritten. Once the data is overwritten you are getting into using tools which are not available to the general public as far as I am aware. Mike
