bsdlabel partiton c error message on new install

[andys]

Hi, 

on a newly installed FreeBSD 7.0 system on a dell 1950 server I see the 
following error from bsdlabel. Is there any known issues with this or is the 
only reasonable explanation that I have managed to mess it up without even 
knowing? :P And should I manually change the partition c to fix the prob? Is 
this safe to do? 

bsdlabel -A /dev/da0s1

bsdlabel: partition c doesn't cover the whole unit!

thanks for any advice, Im not really confident with the FreeBSD disk 
management as I havent used it much, 

thanks Andy.
