I have just reformatted my HD (standard Apple internal HD40 in a MacII) with
Apple HD SC Setup V2.0. Below is what I found when I checked the partitions
(new feature in V2.0).

Title                 Partition Name    Partition Type          Size
-----                 --------------    --------------          ----
Partition Map         Apple             Apple_partition_map     31.5 K
MacDriver             Macintosh         Apple_Driver            16 K
HD [name of my HD]    MacOS             Apple_HFS               40,000 K
Free Space            Extra             Apple_Free              2,099 K

Apparently it allocated exactly 40,000 KB (39.06 MB) as the standard
partition. But, what about the "Free Space"? I don't like to have free
space that I can't use!

So, I decreased the "Free Space" partition to 99 K, and increased the "HD"
partition to 42,000 K. Everything seems to work as before, except that I
now have almost 2 MB more available than before.

Questions (to Apple or anybody else who has answers)
  Why is there a "Free Space" partition?
  Is it likely that I will run into problems because I changed the
     partition sizes?
  How does the Apple driver take care of bad blocks? If a bad block
     is found, will the driver decrease the size of the Apple_HFS
     partition, or will it use a block in the Extra partition?
