I had, after the plate was well filled, piecemeal where hinkopieren the data differently, since the USB controller has dropped read all 500 megabytes. As I got a little panic, I have the plate removed from the case and tried directly to SATA, what has not worked. It was always the message "disk must be formatted before being used." After I copied everything and the board have formatted goes fine. But without USB enclosure. That should not be so :(
