My IT guy came running over yesterday saying there was a good deal on eBay on used laptops...$300. It is a used General Dynamics toughbook with an i7 2.2 ghz processor, 8 gb ram and a 120 mb solid state drive.
I'm surprised that companies like General Dynamics would allow their computers to be sold on the used market. From what I've learned, it is all but impossible to completely erase a hard drive. Police departments have forensic computer people that can extract most anything off a hard drive. While I'm sure these are computers that don't have "company secrets" on them, they still might have information the company doesn't want to get out.
It's the same with copying machines. I saw a show once that showed how most every office copier has a computer module in it that records virtually
everything that has ever been copied on it. Legal documents, bank statements, name it, and they can recover it. It's a bit scary. While I'll admit to not being that computer literate, I would NEVER sell any of my old desktops or copiers I've accumulated over the years. They are all stacked up in my closet.
One of these day's I'll take them out into the desert with a 12 gauge and a couple of garbage bags, and have at them. A show I saw on the Discovery Channel had a police computer forensic guy on. And he said the only way to completely erase a hard drive is to place it on the sidewalk, and smash it to pieces with a hammer. I think 12 gauge slugs would make an excellent substitute for a hammer. And at the same time take less effort, and be a lot more fun.
