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 __________________________________________________ Do You Yahoo!?
