PER DTE DCR TB DESCRIPTION
0 0 0 0 Retries and Error Correction are attempted. Recovered and/or corrected data (if
any) are transferred with no CHECK CONDITION status at the end of the transfer.
no err The transfer length is exhausted.
soft err The transfer length is exhausted. Transferred data includes blocks
containing recovered errors.
hard err Data transfer stops when an unrecoverable error is encountered. The
unrecoverable block is not transferred to the initiator. The drive then
creates the CHECK CONDITION status with the appropriate Sense Key.
0 0 0 1 Retries and Error Correction are attempted. Recovered and/or corrected data (if
any) are transferred with no CHECK CONDITION status at the end of the transfer.
no err The transfer length is exhausted.
soft err The transfer length is exhausted. Transferred data includes blocks
