Okay. You win. Mentioning pseudo-connections is like a reverse Ad-Hominin. If it's true, it's true. Regardless of the speaker. That works both ways. Including the negative.
What I'm saying is that overwriting data through CCleaner and other apps is insufficient to stop top level data-masters from accessing lost data. This will probably only be relevant to fucking terrorists and whatnot, because we're talking about the NSA and stuff that would bother them. The local "hacker" who dumpster-dives old HDDS to get credit card numbers is far beneath our level of security.
I'd talk about how rewriting HDDs doesn't delete old data, but we'd have to talk about some serious shit. Like Quantum mechanics and stuff at the end of it. I don't even understand it. Something about footprints from past writes and stuff. It's all over my head. Sorry.
What I want to make clear, is that in order to destroy data, you need a physical act. I'm talking using a cutting torch to melt the chip. Maybe taking it out the range like I do. Destroy that disc. Your security depends on it. Privacy is your right, and with computers, that means doing certain things.
