- * RD for DO 0, 2nd drive
- * RD for DO 0, 'n'th drive

- * Registration 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 registration data entries
- *
- * FOR EACH DATA OWNER
- * {
- * 4 bytes = secure id of data owner's process
- * 4 bytes = the number of different registration data files
- * for this particular data owner (one for each drive that
- * was backed up)
- * ENTRY
- * {
- * 1 byte = Associated TDriveNumber of the registration data
- * 8 bytes = offset & length of actual registration data
- * }
- * }
