The real question is, why do they have hard drives in the first place?! I find this concept quite disturbing. Imagine how many times in your life you hand over your passport or driver's license for identity validation, someone copies it 'for their records' and you assume the paper copy is destroyed after a while (last time I hired some expensive tools, this happened, but the company gave me the photocopy back when I returned them). Now your private data is sitting on that company's photocopier, probably without anyone having a clue it's made a digital copy as well as a hard copy, and nobody has a hope of controlling it. I struggle to see a legitimate reason for the existence of such a 'feature'.
