     0522  KP called operations supervisor, got instructions                    
           on how to deal with the Mark 5. Rebooted the Mark 5                  
           unit at 0524 UT, rebooted station VME at 0530 UT.                    
     0533  KP reboot of station VME failed to correct                           
           the problem. Mark5 came back with no disc pack                       
           in any bank and it was in IDLE mode. Called                          
           operations supervisor, switched to tape. Called                      
           site tech to notify that the disc pack failed.                       
           Site tech mentioned that there was a note on the                     
           module to watch out for disk drive 2.                                
     0540  KP rebooted station VME to load in the file                          
           to write to tape. Next observing file also sent                      
           out to the site - it will now write to tape. Put                     
           the Mark5 into STMODE.
