Last time I got rid of my wife's and my computer, I pulled the hard drives out, and smashed them with a hammer (a lot). I have a couple of computers that we replaced some time ago, that my wife keeps impinging on my procrastination and wants me to do something with. They are old computers and probably not even usable since they had Windows Vista installed, which the entire web hated but worked just fine for us. In fact Windows 10 didn't seem all that much of an improvement. I read that you can use a program called DBAN to remove everything on the drives. Anyone have any experience with that? Also, Microsoft says just reinstalling the operating system will completely remove all of the files. However I read that reinstalling the operating system does not remove all of the old files COMPLETELY. Since we have passwords, and encrypted off shore accounts worth as much as twenty three dollars and seventy nine cents on them, I want to be sure no one raids them. I intend to trundle them off to Goodwill once I decide what to do with the hard drives. Or alternatively, I can just beat them to a pulp, and send them off with the trash.
