Seriously though, who other than Gil Grissom would find a lightly bent up hard drive lying in the street and try a data recovery on it? Firstly, who knows whether it holds the answers to life the universe and everything, grannys recipes or some kids raving MSN logs on it.
Secondly knowing that the small cracks in the recording surface will mean repeated data loss in the stream, and therefore files will be incomplete requiring weeks or months of a team to interpolate and guess the missing parts and only after (thirdly) the time it takes to modify the bent platter, reinstate the missing/broken drive electronics, extract the raw data and rebuild that data into a workable partition/filesystem structure....if at all possible....and
then only if it was found within a very short period of time so that the surface of the disk wasn't tarnished, or had suffered temperature damage, or the substrate had become water or acid affected and lost adhesion to the surface.
An organisation would have better things to spend their money on and all the individuals with enough time on their hands to do this are currently tied up on some internet forum somewhere
