I’ve found that on some systems and some utility apps, if there are partitions present then doing a zeroing pass only zeros the partition rather than the entire drive itself
Correct, it was the built it disk utility app on Mac. I had a giant drive with a few partitions and clicked to do a zero pass and it finished in a half second. Obviously there was no way it completed that fast. I did some empirical testing based on completion time and sure enough it only zeroes a single partition rather than the entire disk

I’m guessing that is not dd
Yeah, dd does as told and doesn’t care about your tears about the stupid typo

I miss when Disk Utility was good and simple and predictable on MacOS. It’s such steaming shit now.
