I haven't used mdadm, and don't have it installed at this time, but, as best I can recollect, it's in the mdadm manual page. It's --zero<SOMETHING>, I don't remember well at all. Use mdadm to zero the mdadm-related stuff. Sorry, can't remember any more details. Haven't used rad in quite some time. -- Miroslav Rovis Zagreb, Croatia https://www.CroatiaFidelis.hr
