(3) Logical unit Self-Test
When "0" is specified in the "SelfTest" bit and the values other than zero is specified in the "SELF-TEST
Code" field in CDB, the IDD executes the Self-Test specified in CDB. In this case, the INIT can read the
executed results (page code= x10 : Self-Test Result Log Page) by the LOG SENSE command.
The specified values in "PF" bit, "DevOffL" bit and "UnitOffL" bit in CDB are ignored.
The "Parameter List length" field shall contain zero. If the value other than zero is specified in this field,
this command is terminated with a CHECK CONDITION status (ILLEGAL REQUEST [=5] / Invalid
field in CDB [=24-00]).
The "SELF-TEST Code" field specifies the type of executing Self-Test by this command, as below.
SELF-TEST Code
0,0,0 Refer to clause (2), Parameter Specification.
0,0,1 The IDD shall start its short self-test routine in the background mode.
0,1,0 The IDD shall start its extended self-test routine in the background mode.
0,1,1 Reserved
1,0,0 Abort the current self-test running in background mode. This value is only valid if a
previous this command specified a Background self-test function and that function
has not completed. If either of these conditions is not true, then the IDD shall it
respond by returning a CHECK CONDTION status.
1,0,1 The IDD shall start its short self-test routine in the foreground mode.
1,1,0 The IDD shall start its extended self-test routine in the foreground mode.
1,1,1 Reserved
The Self-Test executes the following test segments in ascending order by number:
1. Buffer RAM test
2. Flash ROM test
3. Pre-SMART test
4. Low Level Format test
5. Random seek test
6. Sequential seek test
7. Data compare test
8. Random read test
9. Sequential read test
10. SMART test
