If they were misaligned, you would see a large difference in the tests. A few points one way or other in these is largely meaningless. That being said, if I were you I would set -b 2048(1 MB) as the default, the amount of space wasted is trivial and your partition will always be aligned. People following your tutorials may have a variety of different drives and that setting is safe for all. Windows defaults to this offset for the same reason: DISKPART> list partition Partition ### Type Size Offset ------------- ---------------- ------- ------- Partition 1 Primary 1116 GB 1024 KB -- Adam Vande More _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
