	Table 5-65Verify Error Recovery Page-Field Descriptions (Page 7)
Field	Default	Description
	Value
PS	0	Parameters Savable. This bit is only used with the MODE SENSE command. A returned val-
		ue of 1 indicates that the target is capable of saving the page in a non-volatile, vendor-specific
		location. The bit is reserved with the MODE SELECT command.
EER	0	Enable Early Recovery. Not supported by the drive.
		Post Error Recovery. When the value is 1, the drive returns CHECK CONDITION status for
		recovered errors, sets the sense key to RECOVERED ERROR, and posts the appropriate ad-
PER	0	ditional sense code.
		When set to the default value of 0, it causes the drive to return GOOD status in cases where
		error recovery is invoked and is successful. The only recoverable error that can occur during
		a VERIFY operation is a failed read that succeeds after retries.
DTE	0	Disable Transfer on Error. Not supported by the drive.
DCR	0	Disable Correction. When the value is 1, it disables ECC Firmware only (but not retries) on
		the READ portion of a VERIFY operation. When set to the default value of 0, the ECC cor-
		rection is always applied as a means of recovering erred data.
Verify	4	The Verify Retry Count specifies the number of retries that are attempted per sector on a
Retry Count		failed READ portion of a VERIFY operation.
Verify		The Verify Correction Span specifies the maximum number of bits in a sector that the drive
	240	is allowed to correct. A value less than the default value can cause an otherwise correctable
Correction		error to be reported as uncorrectable. If the initiator specifies a value larger than 80, the drive
Span		rounds down to 80 without reporting the change. A value of 0 causes the drive to use its de-
		fault value. The drive ignores any value in this field.
Verify	0	The Verify Recovery Time Limit specifies (in milliseconds) the maximum time that a retry
Recovery		is attempted on a failed sector during the read portion of a verify operation. The default value
Time Limit		of 0 indicates that there is no time limit. The minimum permissible is 100 milliseconds.

The Caching Page controls the drive’s cache management policy. The data format and field descriptions are described in Table 5-66and Table 5-67respectively.
