I just figured that was implicit and that we were all results-o= riented rather than blame-oriented. Sorry! Simple s/corrupting/detecting corruption/ would do:) No worries, you are not the first one. For me it's just quite interesting to observe how people live for years with h/w corrupting their data and only putting ZFS there reveals the problems. I wonder how many strange UFS-related problems/panics reported over the years are due to buggy hardware. --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
