When error recovery has succeeded, processing of the command is continued.

 

 

 

 

3.

The contents of recovered errors are not reported.

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).
