 The recovered write errors are considered fatal if ST_RECOVERED_WRITE_FATAL

+By default, open() does not block if the drive is not ready. The
+behaviour can be changed by setting ST_BLOCKING_OPEN to one. The
+behaviour can be changed also with the boot/module option
+blocking_open. The blocking open times out after ST_BLOCK_SECONDS.

 The maximum number of tape devices is determined by the define
 ST_MAX_TAPES. If more tapes are detected at driver initialization, the
 maximum is adjusted accordingly.
