Personally I don=E2=80=99t use the -a option of gpart anymore since it = started to do funny magics in front of face. If I remember correct, = gpart of the FreeBSD 9.x-RELEASES was still OK (or was it 8?). Nowadays, = I align all my storage media by employing -b with a reasonable value. Best regards Rolf=
