           Operator is Paul Dyer.                                               
           LA is writing Mark V disc pack NRAO-008 in bank B.                   
           KP is writing Mark V disc pack NRAO-017 in Bank A.                   
           VCLOCK, GPS Delta, and UT1-UTC check ok.                             
     0213  Begin at Y.                                                          
     0230  Begin at GB and all VLBA sites except BR and MK.                     
     0240  New operator is Jim Ogle.                                            
0230-0244 *Y not writing data to tape. A tape was prepassing     SW     100   14
           on drive #1 and for some reason the system did not                   
           start writing on drive #2, it looks like it wanted                   
           to write to the prepassing drive.                                    
     0242 *Rebooted Y VME to see if that would clear up the                     
           problem. After the reboot it started writing to the                  
           tape on drive #1 so I sent a tape terminate command                  
           to force it to switch over to drive #2.
