>From a new installation of Windows 7 and FreeBSD CURRENT:

GEOM: ada0: partition 3 does not start on a track boundary.
GEOM: ada0: partition 3 does not end on a track boundary.
GEOM: ada0: partition 2 does not start on a track boundary.
GEOM: ada0: partition 2 does not end on a track bounary.

Partition 2 is the reserved partition while 3 is an NTFS partition, both
