              - The system was hanging with specific 48-bit LBA hard drives during
                W2k installations.  This issue was fixed.
              - The initialization process in CTRL-M was not properly initializing
                the drives. This issue was fixed.
              - The rebuilding process in CTRL-M was not properly rebuilding the 
                hard drives.  The source hard drive was being written to instead
