Help!: 160 gig only seen as 152 gig??

[Dragoncrest]

	I have a Freebsd workstation running 4.9 on an Epox 8k9A2+ MB and the 
silly thing sees my brand new Western Digital HD as 160gig in the bios, but 
BSD only sees it as 152gig.  Now 8 gig isn't all that bad of a thing to 
loose on a drive that big, but still, it's too weird that I would be unable 
to get to that last 8 gig.  When going into Fdisk I get the error that the 
geometry on the drive is wrong and it suggests a much more appropriate, 
albeit smaller, geometry.  Is this something I'm doing wrong in setting up 
the drive, or is this a limitation or problem in BSD?  Or is it simply a 
limitation of the hardware?  I'm not going to cry over 8 gigs lost, but I 
would really like to know if there's something that can be done to fix 
this, or am I kinda SOL?
