When using the 3DISK386.EXE or 3DISK.EXE program for low-level
formatting and partitioning on 3Server, 3Server3, 3S/400- and 3S/500-series
dedicated servers, watch out for the following question during partitioning:

            Volume 0:
    -->     Cluster size? [ 1 , 2 , 4 , 8 , 16 , 32] (4) _


Server Reference and Service Manuals define "Cluster size" as:

      (bytes per sector) * (sectors per cluster) expressed in KB

Therefore, the default "Cluster size" in this example, enclosed with (),
would be 4 or 4 KB.  However, the question asks for the sectors per cluster
given a sector size of 512 bytes (the default sector size on a 3Server boot
partition).  In the above example, the default 4 would not mean a 4 KB
cluster size, but 4 sectors per cluster (with a default sector size of 512
bytes) resulting in an actual 2 KB cluster size.
