    Summary: disk file corruption
    Collaboration=Brahms
    I have been creating GEANT output files for subsequent "replay" on
    /brahms/data07.  The files are created with LSF batch jobs. These files 
    seem to
    be getting corrupted with subsequent disk activity.  As a test I 
    created a
    short file /brahms/data07/sanders/simu/gbrahms_output/sim_187.cdat.   I 
    tested this file using a simple program to dump the geant file header 
    and the output looked fine.  I also made a
    duplicate of the file, which also tested fine.  After starting some 
    additional
    geant simulations, I went back to test the original files and found 
    that some
    of the header information seemed to have been scrambled. The duplicate 
    file
    also seemed to be corrupted. The size of the files did not change.   
    The short run was done after encountering problems over the past day of 
    programs that seems to be working suddenly failing.  I might also note 
    that older files that I created on the disk seems to continue to work 
    fine.
