Does FreeBSD start slices at head boundaries?

Hi All,

Installing FreeBSD 8.x I select "A" at the fdisk partition editor to
use the entire disk.  It creates an unused slice with offset 0 and 63
sectors in size.  Then partition 1 starts at sector 63 and utilizes
the remaining disk space.  Does sysinstall's diskPartitonEditor macro
automatically start partitions at head boundaries?  The reason I ask
is because I am most familiar with sector 64 being the start of a head
boundary as opposed to 63.  Is my understanding incorrect?

Take care
Rick Miller
