DiskDriveTestType | uint16 |
Description | string | The descriptions for each Disk Drive test type are below: * "Short Self-Test" (value=2) is specified for the test that performs a small set of vendor-specific tests to verify that the disk is operating properly. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Media Verify (value=6). * "Extended Self-Test" (value=3) is specified for the tests that performs an extended set of vendor-specific tests to verify that the disk is operating properly. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Media Verify (value=6). * "Selective Self-Test" (value=4) is specified for the test that performs an extended set of vendor-specific tests to verify that the disk is operating properly, but limited to a specific LBA range of the disk. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Media Verify (value=6). * "Sequential Read" (value=5) is specified for the test that performs a read operation from all disk sectors in sequential order. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Media Verify (value=6). * "Random Read" (value=6) is specified for the test that performs a read operation from disk sectors in random order. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Media Verify (value=6). * "Sequential Read-Write-Read Compare" (value=7) is specified for the test that verifies that read and write operations are performed properly for a selected LBA range. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Media Verify (value=6). * "Random Read-Write-Read Compare" (value=8) is specified for the test that verifies that read and write operations are performed properly for a selected LBA range. Disk sectors are tested in random order. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Media Verify (value=6). * "Sequential Internal Verify" (value=9) is specified for the test that verifies the ability to perform read and verify operations from track to track and head to head in sequential order for a selected LBA range. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Media Verify (value=6). * "Status" (value=10) is specified for the test that returns information that relative health of the disk drive based upon internal analysis of failure statistics. CIM_DiagnosticTest.TestTypes shall be set to Health Check (value=4). * "Grown Defects" (value=11) is specified for the test that retrieves statistics (such as the number of remapped sectors) collected by the disk drive regarding its sector remap mechanism. CIM_DiagnosticTest.TestTypes shall be set to Stress (value=4). * "4K Alignment" (value=12) is specified for the test that verifies that blocks can be properly aligned on 4K boundaries. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2). * "Power Management" (value=13) is specified for the test that verify that all system interface for cables and connectors are working properly. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2). * "Performance" (value=14) is specified for the test that verifies that the disk operates within the vendor/product specific performance ranges for data read operation transfer rates, sequential seek times and random seek times. * "Conveyance" (value=15) is specified for testing for damage in transit. CIM_DiagnosticTest.TestTypes shall be set to Functional (value=2) and Stress (value=6).
