The problem is that you do indeed have the geometry wrong.  Disks hanging
off of Adaptec controllers have one of two geometries:

Extended translation enabled - 64 heads, 32 sectors/track,#MB reported cylinders
							   by diskprobe 

Extended translation disabled- 255 heads,63 sectors/track,#MB reported cylinders
							   by diskprobe/7 

Determine whether you have extended translation enabled or not, and go from
there.  Once way to almost assure sucess is to create a small partition on
the disk with DOS.  The FreeBSD install will then take the values from that
partition and use them for creating all others even if you decide to delete
the DOS partition during the install.
