Parameter Data Formats

f.PER (post error)

"1" : When several errors (errors related to the disk drive), which were recovered from normally through the IDD's error recovery processing, have been detected, a CHECK CONDITION status is reported when execution of that command is completed. In the sense data generated at this time, the sense key indicates "RECOVERED ERROR [=1]" and the content of the first error to be corrected successfully is reported.

"0" : Even when several errors (errors related to the disk drive), which were recovered from normally through the IDD's error recovery processing, have been detected, that command is completed with a GOOD status and the contents of the recovered errors are not reported.

g.DTE (disable transfer on error)

"1" : Even when several errors on the disk drive, which were recovered from normally through the IDD's error recovery processing, have been detected, execution of that command terminates at that point.

"0" : When several errors on the disk drive, which were recovered from normally through the IDD's error recovery processing, have been detected, execution of that command is continued.

The IDD disregards this bit and operates according to the default value (=0).

h.DCR (disable correction)

"1" : Even when a correctable data check has been detected, data correction according to the ECC is prohibited. However, On-the-fly correction processing is not prohibited.

"0" : When a correctable data check has been detected, data correction according to the ECC is applied.

The IDD disregards this bit and operates according to the default value (=0).

i.Number of retries during read

This parameter specifies the number of retries that should be executed for "Data Check" type errors detected in read operations on the disk media. The number of retries specified in this parameter is the maximum number of times reading is retried for each individual portion of data in each logical data block. If the IDD cannot perform correction of the data On-the-fly for each portion of data in the data block, it retries the reading of those portions. The reread retry is executed the number of times specified by the drive parameter internally by the IDD before this retry is executed, so actually the retry is executed the number specified here plus the number of internal retries.

The value specified in this parameter is applicable to the READ/READ EXTENDED commands and the read test in the SEND DIAGNOSTIC command.

When the page length in Page 1 is specified as X '06,' the value specified in this field is copied to the "Number of retries during WRITE" on this page and "Number of retries during VERIFY" on Page 7.
