Grigori -

My understanding is that ERROR_STATE is set Yes when the volume suffers what is 
termed a "permanent I/O error", where retries (as reflected in READ_ERRORS, 
WRITE_ERRORS) cannot get by the problem spot on the tape.  At that point the 
volume is rendered readonly, and the administrator needs to deal with it.  
Sometimes, the problem is just a dirty read/write head on the tape drive.
