I have a couple of old laptops lying around and want to throw them away, but have been cautious to do so because of privacy concerns of data still on the hard drives. What is the best way to wipe them? Or should I take them out and physically destroy them?
They are running windows vista and 10 I think.
If you just do the simple one-pass zero-ing out, suggested a few times here, the data is only recoverable in theory. There are labs that do it, but they charge thousands of USD for a drive and giving limited results.
Unless you are being actively targeted by deep pockets, that’s plenty good enough.
And if you do a couple passes (might take a bit but who cares if youre throwing the whole thing out) then in theory even the nsa can’t get in it
