It is what I expect from dd. I did such things with OpenBSD before.

That is what I wanted. I was deleting some old disks. I filled it
with zeroes and not random in order not to make the process
slower. Perhaps there is a faster tool than dd.

I know, the better way to delete is to destroy physically the disk,
at best to burn and melt it.
