HDD Geometry Issues

My HDD is an ST340810A 3.31. The BIOS gives its stats as:
Cylinder: 19158
Head: 16
Precomp: 0
Landing Zone: 19157
Sector: 255
I found the official doc at
http://www.seagate.com/support/disc/specs/ata/st340810a.html although
I'm not too sure how to interpret it.
When I go to allocate disk space during install, it says that a
geometry of 77545/16/63 is incorrect and uses instead 4865/255/63. Even
when I reset the geometry to 19158/16/255, it says that's wrong too.
If I use the entire disk with 'A', I see:
Offset Size(ST) End Name PType Desc Subtype
0 63 62 --- 12 unused 0
63 78156162 78156224 ad0s1 8 freebsd 165
78156225 9135 78165359 --- 12 unused 0
