Error Recovery Procedure
1. Rereading is tried repeatedly up to the number of times specified in the
"Read Retry Count", "Write Retry Count" or "Verify Retry Count"
parameter. If possible, data correction is executed afterward 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.
