Because of the number of times I've seen the question, I'm posting this reply
anyway. I'll mail a copy to John directly.
Extra space exists on all hard disks partitioned by HD SC Setup's default
partitioning options. A decision was made to create standard default
partitions because of Apple's need to source drives from different
manufacturers. Since few hard drives, even from the same manufacturer, have
identical storage capacity, we decided to make standard partition sizes for
each of the Apple Hard Drives - 20, 40, 80 and 160. Standard partition
sizes reduce support problems caused by restoring image backups between
different sized partitions and worrying about "Bill's drive having 2.8K
more space than mine." etcetera.
Other than the above, I can't think of any reason why you shouldn't use
the custom partition option to make whatever sized partition you desire.
