Running the test

Before you run the test, complete the test setup as described in the test requirements: Hard Disk Drive Testing Prerequisites.

Troubleshooting

For troubleshooting information, see Troubleshooting Device.Storage Testing.

noteNote
The devcon tasks may fail. If they fail with ExitCode=1, restart the system and run the test again. If the tasks fail with ExitCode=2, the driver install or driver removal failed - most commonly because the test system is not configured for AHCI (SATA) mode. This test will not pass for a system in PATA emulation mode.

More information

Trim is a Data Set Management command feature described in the ATA/ATAPI Command Set-2 (ACS-2) or later. For more information about the ATA/ATAPI specification, visit the T13 Technical Committee Web site.

This test installs a test miniport based on msahci, which provides a framework for validating hardware. The Trim Test uses this ATA Miniport Hardware Validation framework to generate and measure the effects that Trim has on device performance. When the test completes, the test miniport will be uninstalled.

This test may trim or overwrite any or all of the sectors on the test device. As a result, the data on the drive will be lost. This test must be run against a secondary SATA device running in AHCI mode
