+     * System Data
+     * ===========
+     * 
+     * This is the format of the data written by the
+     * CMMCScBkupStateArchiveOpSystemData object
+     * 
+     * 
+     *  SYSTEM DATA for DO 0
+     *  {
+     *      SD for DO 0, 1st drive
+     *      SD for DO 0, 2nd drive
+     *      SD for DO 0, 'n'th drive
+     *  },
+     *  SYSTEM DATA for DO 1
+     *  {
+     *      SD for DO 0, 1st drive - (System data is only on
+     *      SD for DO 0, 2nd drive    two drives)
+     *  },
+     *  SYSTEM DATA for DO n
+     *  {

+     * System Data Index
+     * =================
+     * 
+     * This is the format of the data written by this object.
+     * The format allows the possibility of a future partial
+     * restore (hopefully).
+     * 
+     * 
+     *  4 bytes = count of system data entries
+     *
+     *  FOR EACH DATA OWNER
+     *  {
+     *      4 bytes = package id associated with a system data owner
+     *      4 bytes = the number of different system data packages
+     *                for this particular system data owner (one for each 
+     *                drive that was backed up)
+     *      ENTRY
+     *      {
+     *          1 byte = Associated TDriveNumber of the system data
+     *          8 bytes = offset & length of actual registration data
