I am running Windows File Recovery on my 1TB M.2 SSD and I am appalled at how much data is recoverable. When I delete something I expect it to be deleted. Gone. Irrecoverable. Can I do this with already deleted files?
I was thinking and my method might be to run all of the files I want to delete through an application I’d write which would 0 the files first.
Marking this as data recovery though it is more the prevention of data recovery.

Just because File Recovery says it’s recoverable doesn’t mean it is. Even though the directory entry is still on the drive the corresponding sectors may already be overwritten.
Why are you worried?
I see going through the files that they have been filled with random bytes. While good I’d rather they not be there at all. Not only is it a privacy concern, but as stated I would rather things I delete be gone. Simple as.
Just do a full disk encryption on the drive. Problem solved.
You should be aware that deleting a file just deletes the pointer to the file. It doesn’t over write it. That’s very important for a person who will be coding applications to be aware of.
I’m aware, I’ve been in software development for over 10 years now. I just thought it would’ve reutilized those sections by now.
