SCSI Description
Maxtor Atlas 10K III
5-49
RC
0
Read Continuous. When the value is 0, the drive attempts error recovery
when it encounters an error. When the value is 1, the drive suppresses error
recovery.

EER

Enable Early Recovery.

PER
0
Post Error Recovery. When the value is 0, the drive returns a GOOD status
in cases where error recovery is invoked and successful.
When the value is 1, the drive returns a CHECK CONDITION status for re-
covered errors, sets the sense key to RECOVERED ERROR, and posts the
appropriate additional sense key.
DTE
0
Disable Transfer on Error.

DCR
0
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
to each data sector regardless of the value in the DCR bit.
When the value is 1, ECC correction is disabled (but not retries or reads),
and ECC errors cannot be corrected. However, on-the-fly is always enabled.
Read Retry
Count
4
Specifies the number of retries attempted for a failed read operation.
Correction
Span
170
Specifies the maximum number of bits in a data sector that the drive is al-
lowed to correct. A value less than the default value can cause an otherwise
correctable error to be reported as uncorrectable. If the initiator specifies a
value larger than the default value, the drive automatically rounds down the
number to the default value. A value of 0 causes the drive to use the default
value. The drive ignores any value placed in this field.
Head Offset
Count
0
Not supported by the drive.
Data Strobe
Offset Count
0
Not supported by the drive.
Write Retry
Count
8
Specifies the number of retries attempted for a failed write operation.
Recovery
Time Limit
0
Specifies the maximum time, in milliseconds, that a retry is attempted on a
failed sector during a read or write operation. When the value is 0, it means
that there is no time limit. The minimum permissible value, however, is 100
milliseconds.
