Error Recovery Procedure
1. When a correctable data check is detected, immediately, correction is executed
according to the ECC. For data checks which cannot be corrected, rereading is
tried repeatedly up to the number of times specified in the "Read Retry Count",
"Write Retry Count" or "Verify Retry Count" parameter. However, if a
correctable error is detected during reading, data correction is executed at that
point according to the ECC.
2. When error recovery has succeeded, processing of the command is continued.
3. The contents of recovered errors are not reported.
4. If unrecoverable errors have been detected, execution of that command is
terminated at that point.
5. Transfer of data in blocks which include unrecoverable errors to the INIT is
done in accordance with the specification in the TB bit (read commands).

done in accordance with the specification in the TB bit (read commands).
5. When recovery from all detected errors has been successful, a CHECK
CONDITION status (RECOVERED ERROR [=1]) is reported after all
processing of the command is completed and the sense data indicate the
content of the last error that was successfully recovered from and the address
of the data block where that error occurred. However, if the error is corrected
with ECC only, the CHECK CONDITION is not reported and no sense data is
created.
(Setting prohibited) (See *1 at the end of this table.)
