						Table 5.3	Sense data error classification	(4 of 4)
K*			C*		Q*		Error contents		L*	Recovery method
										(See Table 4.4.)
B			03		xx	Peripheral device write fault			Need	12
			11		xx	Unrecovered read error
			13		xx	Sync byte not found for data field
			14		xx	Record not found
			15		xx	Mechanical positioning error
B			43		00	Message error			Need	6
			45		80	Select/Reselect failure
			47		00	SCSI parity error
			48		00	INITIATOR DETECTED ERROR message received
			49		00	Invalid message error
						An unrecoverable SCSI related error occurred in
						the command execution sequence.
B			4E		00	Overlapped commands attempted			None	2
						Before execution of a command was completed, a
						new command was issued by the same INIT.
			4D		nn	Tagged overlapped commands
E			1D		00	Miscompare during verify operation			None	24
						Data failed to match in the Byte check mode of the
						Verify command.

						Table 5.4	Error recovery processing procedures (1 of 5)
Recovery							Recovery Processing Procedure
Method
		0		It is not necessary to perform the error recovery processing. Continue processing.
		1		Error recovery processing is impossible. Terminate processing.
		2		This is a programming error and error recovery processing is impossible. Terminate
				processing and correct the error in the system (INIT) programming.
		3		This is an error in the SCSI protocol and error recovery processing is impossible. Terminate
				processing and check the system's SCSI bus operation.
		4		1) Reissue the original command. (Retry)
				2) If the command is terminated with the same error when retried, perform recovery
					method 3 or 1.
				3) If the command is terminated with a different error when retried, execute the recovery
					processing procedure for that error.
