Maxtor 10K III manual Guetkrvkqp

SCSI Description

(KGNF		&GHCWNV		&GUETKRVKQP
			Disable Reassign Copy. When this field = 0, the disk drive copies best-
			guess data to the new physical block during REASSIGN BLOCKS command
			processing. If the disk drive cannot successfully read the original block’s da-
DRC		0	ta, the disk drive sets a Forced Error flag in the replacement block’s flags.
			When this field = 1, the disk drive does not copy a block’s data and obtain
			best-guess data; it first reassigns the block and then writes data to the
			block. Until it is overwritten by a subsequent WRITE command, a reassigned
			block’s data is undefined and its Forced Error flag is set.
NMAIOP		0	No MAIOP. When this field = 1, MAIOP is disabled.
DNTRA		0	Disable Next Track Read Ahead. Do not prefetch next track.
Soft Fault		0	When this field is set = 1, the disk drive’s FAULT led illuminates.
			Manual Calibration. When set = 0, the disk drive runs calibration and diag-
			nostic procedures periodically.
			When set = 1, calibrations occur only as a result of a REZERO UNIT com-
ManCal		0	mand.
			Note that this bit is not saved by MODE SELECT when the value of the SP
			field is 1.
DPER		1	Disable Post Error Recovery. When set = 1, disables Post Error Recovery
			(refer to Read-Write Error Recovery Page, Section 5.17.3.3).
			Force AxRE where x = W (WRITE) or (READ)
			When set = 0, the settings of AWRE/ARRE are as set in Mode Page 01h
FAxRE		1	(Read-Write Error Recovery Page).
			When set = 1, Automatic WRITEs or READs are forced, even if the related
			fields of Mode Page 01h are = 0.
			Quick Disk Error Recovery. When set = 0, disk error recovery has no
QDER		0	20msec limit.
			When set = 1, disk error recovery time allotted is less than 20msec.
			Disable Format Certification. If set = 1, format certification is disabled re-
DFC		0	gardless of the value of the DCRT bit in the FORMAT Command’s parameter
			header.
Read Ahead		0	If set = 1, disables READ ahead.
Disable
Enable
Double Ack		0	If set = 1, enables the double acknowledge filter.
Filter
ESPDis		0	ESP Disabled. If this field = 1, ESP (anticipatory READ) is disabled.
DFRCSU		0	Disable Filling of Revector Cache on Spin-Up. When this field = 1, revec-
			toring cache is not refilled on spin-up.
			Asynchronous Information Protection (AIP) Generation Disabled. When =
AIP Gen		0	0, drive places AIP information on the upper byte of data during asynchro-
Disable			nous information phases, regardless of the setting of “AIP Check Enabled.”
			When set = 1, AIP generation is disabled.
			AIP Checking Enabled. When = 0, the drive will ignore AIP information for
			this initiator. When = 1, the drive is able to validate incoming AIP informa-
			tion on upper byte of data during asynchronous information phases and can
AIP Check		0	generate errors on bad information.
Enabled			NOTE
			This bit is maintained uniquely for each unique initiator ID that senses or se-
			lects it. All initiators that want to participate in AIP must set this bit for
			themselves.
AIP Capable		1	When = 0, indicates that drive does not support AIP. If = 1, indicates drive
			is capable of AIP.
			When this field = 0, “total bytes read/written” field on Log Page 02h and
LogPgB		0	03h reported as number of	. When = 1, field is reported as number of
			.
