Break: Indicates how to terminate the loop count should an error occur.
0 = stop on first error
1 = do not stop on error
Loop Count Identifier: The number of times that the test should be repeated before status is returned.
0 = Continuous
1 = run once
2 = run 10 times
3 = run 100 times
4 = run 1000 times
Parameters A, B, C: Any additional parameters required to fully define the diagnostic test. These parameters are
unused and shall be 00h for all diagnostics except for tests 02, 03, and 43 to 48. These tests are described in
clause 7.2.7.
8.2.4.
Diagnostic Test Number Summary
The following is a list of the diagnostic capabilities of the SDX-560V. The Test Availability Code indicates if a
particular test can be executed by the Host computer or is executed during Power-on diagnostics (or both). The
drive also supports three types of diagnostics:
1.
Individual Tests - Self contained modules designed to test a particular function of drive
2.
Sequences - Automatic execution of a series of individual tests
3.
Exercisers - Verification of a major function of the drive such as Read, Write, Search, etc.
The Diagnostic Test Number for each Test, Sequence or Exerciser is shown in the first column.
Test Availability Codes
P – Power-onSelf-test
H – Host Diagnostics
PH – both
