So be careful when This is the HPA or "Host Protected Area", and it's kind of a standard on many drives these days (search on Google for it). I think it was ATA-4 which first implemented it. Some info here: http://www.sleuthkit.org/informer/sleuthkit-informer-17.html#hpa and here: http://www.techpathways.com/webhelp/Advanced_Tips/Advanced_tips_and_tricks.htm It seems strange that FreeBSD doesn't account for the HPA, but stranger things have happened... -- Regards, Torfinn Ingolfsen, Norway
