           Called oncall site tech Bob Sanderson, left message                  
           on answering machine and voicemail. Will wait for a                  
           few minutes to see if anyone shows up at site or                     
           Bob calls back. If he doesn't, will call Mark                        
           Hofmann.                                                             
     2003  BR Bob called from the site, said that he thought                    
           that he had three passes available and that he had                   
           timed things so there wouldn't be a loss of data.                    
           Figured out that the "problem" was the change in                     
           data rate from the previous file (128 Mb/sec) to                     
           this one (256 Mb/sec); TRACK ended pass 12 early                     
           due to the data rate change. New tapes are mounted.
