Table 4.48 Error recovery control flags during the self-diagnosis test

PER	DTE	Diagnostic test operation
0	0	The diagnostic test continues when error recovery is successful. The contents
		of recovered errors are not reported. When an error which cannot be recovered
		from is detected, the diagnostic test terminates at that point with an error.
1	0	The diagnostic test continues when error recovery is successful. When an error
		which cannot be recovered from is detected, the diagnostic test terminates at
		that point with an error. Even when all the detected errors have been recovered,
		a CHECK CONDITION status (RECOVERED ERROR [=1]) is reported after
		the series of diagnostic tests is completed and the sense data show the contents
		of the last error to be successfully recovered from.

When "1" is specified in the "SelfTest (self test)" bit in this command, the command execution results are reported by the status byte and the sense data. Therefore, even if the RECEIVE DIAGNOSTIC RESULTS command is executed after this command, the self-diagnosis test execution results are not reported as response data.

(2) Parameter specification

When "0" is specified in the "SelfTest (self test) bit in the CDB, the HDD executes the operations specified in the parameter list transferred from the INIT by this command. In this case, the HDD reports a GOOD status and terminates this command at the point when preparation of the "response data" is completed after completing the specified operations. The INIT can read the execution results (response data) by the RECEIVE DIAGNOSTIC RESULTS command.

When the "PF (page format)" bit in the CDB is "1," the parameter list transferred from the INIT by this command shows the page format, explained later, but the HDD disregards the value specified in this bit and always handles the page format according to the specifications in the parameter list when the parameter list is transferred by this command. Also, when the "SelfTest (self test)" bit is "0," the specifications in the "DefOfl (device off-line)" bit and the "UnitOfl (unit off- line)" bit have no meaning and their specified values are disregarded.
