  Revision History
  Date      Who  Comment
  ________  ___  _____________________________________________________________
  03/01/02  cds  initial version
  03/15/02  tbh  keeping it up to date as additional code becomes functional
  04/02/02  tbh  added ms_media_copy_sector
  04/19/02  tbh  added ms_media_resolve_conflict
  06/03/02  cds  uncommented ms_media_copy_sector override
  06/20/02  cds  removed obsolete #if k_log_lun_ms < k_max_log_lun guard
  11/02/02  tbh  added ms_media_is_phyblock_wp (but didn't need it after all).
  11/03/02  cds  replaced ms_media_is_phyblock_wp with ms_media_is_phyblock_reserved, 
                 overriding media default
