Error Recovery Parameters

TABLE 2-9-1B ERROR RECOVERY DESCRIPTIONS (CONTINUED)

Value	Description
10h	If data transfer can be maintained, the maximum error recovery procedures available
	are used. (RC=1) If an error occurs which is uncorrectable with the error correction
	codes (ECC) on the media, or is uncorrectable in time to maintain data transfer, the
	data transfer is not terminated. However, when the data transfer has completed Check
	Condition status is reported. The sense key is set to Medium Error. the information
	bytes give the address of the block where the first unrecovered error was detected.
	Recovered errors are not reported.
11h	If data transfer can be maintained, retries of the read operation and CIRC are used
	(layered error correction is not used). (RC=1) Only CIRC unrecovered data errors are
	reported. If a CIRC unrecovered data error occurs, data transfer is not terminated.
	However, when the data transfer has completed Check Condition status is reported.
	The sense key is set to Medium Error. The information bytes give the address of the
	block where the first unrecovered error was detected. Recovered errors are not
	reported.
14h	If data transfer can be maintained, the maximum error recovery procedures available
	are used. (RC = 1.) Recovered data errors are reported. If a recovered data error
	occurs, data transfer is not terminated. However, when the data transfer has
	completed Check Condition status is reported. The sense key is set to Recovered
	Error. The information bytes give the address of the block where a recovered data
	error was detected. If an data error occurs which is uncorrectable with the ECC
	information available on the media, or is uncorrectable in time to maintain data
	transfer, the data transfer is not terminated. However, when the data transfer has
	completed Check Condition status is reported. The sense key is set to Medium Error.
	The information bytes give the address of the block where the first uncorrectable
	error was detected. Reporting unrecovered errors takes precedence over reporting
	recovered errors.
15h	If data transfer can be maintained, retries of the read operation and CIRC are used
	(layered error corrections not used). (RC = 1.) Recovered data errors are reported. If
	a recovered data error occurs, data transfer is not terminated. However, when the data
	transfer has completed Check Condition status is reported. The sense key is set to
	Recovered Error. The information bytes give the address of the block where a CIRC
	recovered data error was detected. If an unrecovered data error occurs, data transfer is
	not terminated. However, when the data transfer has completed Check Condition
	status is reported. The sense key is set to Medium Error. The information bytes give
	the address of the block where the first unrecovered error was detected. Reporting
	unrecovered errors takes precedence over reporting recovered errors.
20h	The maximum error recovery procedures available are used. If an error occurs which
	is uncorrectable with the error correction codes (ECC) on the media, data transfer is
	terminated with Check Condition status. The lock with the error is transferred. The
	sense key is set to Medium Error. The information bytes give the address of the block
	where the unrecovered error was detected. Recovered errors are not reported.
