7.2.4. Diagnostic Test Number Summary
The following is a list of the diagnostic capabilities of the drive. 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.
