Error Recovery Parameters
- 39 -
2.9.1 Error Recovery Parameters
NOTE: When the bit definition of this error recovery parameter and the error recovery
procedure (described later) are not in agreement, the error recovery procedure takes
priority.
DCR (Disable Correction)
If “1”, data is transferred without Layered ECC (L-ECC) error correction.
If “0”, L-ECC error correction is performed. The default value is 0.
DTE (Disable Transfer on Error)
If “0”, transfer of recovered data is allowed. The default value is 0.
When both the DTE and PER bit are 1, the target stops the data transfer
immediately if the error is detected, and then returns Check Condition status.
NOTE: The TB bit controls whether data from the bad block is transferred.
PER (Post Error)
If “1”, the drive returns a Check Condition status for a recovered error.
If “0”, no Check Condition status is returned for the recovered error.
The default value is 0.
EEC (Enable Early Correction)
This bit must be 0: The defined retry procedure is performed prior to the error
correction.
RC (Read Continuous)
Set to 0. A delay in the data transfer may occur due to an error recovery action.
TB (Transfer Block)
If “1”, uncorrected data blocks will be transferred to the initiator.
If “0”, uncorrected data blocks are not transferred. The default value is 0.
NOTE: in either case, the block address returned to the REQUEST SENSE command
is not of the preceding good block but of the error block.
Retry Number specifies how many times the drive re-tries a physical read operation
when it finds an uncorrectable block. The default value is 4.
