SCSI Description

				Caching Page-(Page 8)
				Parameters Savable. This bit is only used with the MODE SENSE com-
	(KGNFPS		￿&GHCWNV8CNWG1 ￿	mand. A returned value of 1 indicates&GUETKRVKQPthat the target is capable of saving
				the page in a non-volatile, vendor-specific location. Bit reserved with
				MODE SELECT command.
				Write Cache Enable. The default value of 1 enables write-back caching
				when processing a WRITE command. When set to 0 the drive returns a
				GOOD status and COMMAND COMPLETE only after successfully writing
				all the data to the media.
				When WCE = 1, write-back caching is enabled while processing a WRITE
				command. The drive returns a GOOD status and COMMAND COMPLETE
				only after fetching the data from the initiator and placing it in the drive’s
	WCE		1	cache memory.
				Note: For maximum data integrity, it is strongly recommended that when
				WCE is set to 1, the Read-Write Error Recovery Page (01h) fields be set
				as follows:
				• AWRE to 1
				• RC to 0
				• DCR to 0
				• Correction Span set to 170
				• Head Offset to 0
				• ServoTableOffset5-71to 0
				Multiplication Factor (value must be 0). The drive interprets the minimum
	MF		0	and maximum pre-fetch fields values in terms of the number of logical
				blocks for each of the respective types of prefetch.
				Read Cache Disable. The default value of 0 enables the read cache capa-
				bility and allows the drive to use cache-resident data or medium data to
	RCD		0	satisfy a READ command.
				When the value is 1, read caching is disabled and the data returned in re-
				sponse to a READ command is fetched from the medium and not from the
				drive’s cache memory.
	Demand Read			This field advises the drive on the retention priority to assign data read into
				the cache that has also been transferred from the drive to the initiator.
