A single pass of zeroes is unrecoverable. Flat out. No "unrecoverable unless you have nation-state budget" caveat, it is flat-out impossible to recover data that's been overwritten by anything. Very old (like before you were born old) hard drives may have had recoverable bits and pieces IN THEORY, but modern drives already have to employ borderline magical levels of precision and extensive error correction in order to work at all.Regardless of what you choose to wipe it with, be that all zeroes, ones, a pattern, or random values, there's no known technology that can recover what was on there before. As far as I can find, all of the "you have to go over it 20 times with random data" paranoia stems from a single paper from the 80s. And that wasn't even saying recovery was possible, just theories on how it MIGHT be possible and ideas on what would be needed to truly wipe data if it were.
