When the value is 1, the drive returns a CHECK CONDITION status for re-

 

 

 

 

 

 

covered errors, sets the sense key to

ECOVERED ERROR, and posts the

 

 

 

appropriate additional sense key.

Disable Correction. When the value is 0, ECC correction is applied as a

 

 

 

means of recovering erred data. On write operations, a valid ECC is written
