4.1 Mode Parameters

j.Correctable bit length

This parameter indicates the burst error length (bit length) which it is possible to apply data correction according to the ECC to. It is impossible to change this parameter from the INIT. The IDD disregards the value specified in this parameter and operates according to the "Default" value.

k.Head offset count (not supported)

This field specifies in two's-complement notation an incremental offset position from the track center to the radial position the heads are moved. Any value specified in this field does not preclude the device server from using positive or negative head offset during error recovery. However, after any error recovery is completed the device server returns the head offset to the value specified in this field.

The IDD is not supported this field. Therefore, the IDD ignores the specified value in this field.

l.Data strobe offset count (not supported)

This field specifies in two's-complement notation an incremental position to where the recovered data strobe is adjusted from its nominal setting. Any value specified in this field does not preclude the device server from using positive or negative data strobe offset during error recovery. However, after any error recovery is completed the device server returns the data strobe offset to the value specified in this field.

The IDD is not supported this field. Therefore, the IDD ignores the specified value in this field.

m.Number of retries during write

This field specifies the maximum number of times writing of data to the disk media is retried in the case that there has been an interruption in a write operation such as a shock. The number of retries specified in this field is applied to each logical block unit. When zero is specified in this field, retrying of writing to the disk is prohibited.

The value specified in this field is applicable to the WRITE command, WRITE EXTENDED command, write operation in the WRITE AND VERIFY command and write 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 not transferred from the INIT, but in this case, the value specified in the "Number of retries during READ," on the same page, is also applied to this field by the IDD.
