! PER (Post Error) of one indicates that the drive reports recovered errors. PER of zero disables the reporting of recovered errors. ! DTE (Disable Transfer on Error) is ignored, but it must be set to zero if PER is set to zero. ! DCR (Disable Correction) of one indicates that the off-line ECC correction is not used for data error recovery. A DCR of zero indicates that the off-line ECC correction is used. ! Read Retry Count sets a limit on the ERP steps in which the drive attempts to recover read errors. A value of zero disables all ERP. When ECRC (Mode Page 0) is set to zero, a value of non-zero enables all ERP steps. When ECRC is one, the value in Read Retry Count sets the maximum steps of ERP. ! Correction Span is ignored, and the drive always uses its maximum correction capabilities. ! Head Offset Count is ignored. ! Write Retry Count sets a limit on the ERP steps in which the drive attempts to recover write errors. A value of zero disables all ERP. When ECRC (Mode Page 0) is set to zero, a value of non-zero enables all ERP steps. When ECRC is one, the value in Write Retry Count sets the maximum steps of ERP. ! Recovery Time Limit is a timer for the maximum command execution time (AVERP is set to one, Mode Page 0) or the maximum accumulated ERP time (AVERP is zero). The unit of timer value is 1 ms which must be from 40 ms to 65535 ms (65.5 seconds). If time out occurs, a CHECK CONDITION will be returned. Ultrastar 146Z10 hard disk drive specifications 89
