Binlog errors

This seems to be a frequent occurrence:  

[root@mexxxx01 dblog]# mysqlbinlog mysql.000025 /*!40019 SET @@session.max_insert_delayed_threads=0*/; ERROR: Error in Log_event::read_log_event(): 'Found invalid event in binary log', data_len: 94, event_type: 15 Could not read entry at offset 4:Error in log format or read error  

This is happening to all my binlogs (other servers as well) all the time. There is nothing wrong with the drive- I have other data on there that never gets corrupted.  

[root@mexxxx01 dblog]# ll
