I find that very hard to believe.
Not really. My wife is a programer and paranoid about personal and financial data that we keep on the computer. She insists I smash it. I am not going to take the drive apart to make sure the disk is totally destroyed so it goes into the fire in the backyard when I burn all the damn credit card offers I get in the mail along with old bank statements etc. It takes longer to get the drive out than to smash and burn. I put it on the shelf until the next time I am burning paperwork and toss it in the fire.
Dumpster diving is one of the favorite methods of identity theft.
