In this embodiment, a test method for SSD Controller Reset is provided, in which a microsoft free devcon tool is used to write batch scripts, and a high-frequency Controller Reset test is performed on an SSD.

In a particular test environment, the hardware requirements include: the computer to be tested is a suggested ThinkPad P70 notebook computer. Remarking: for the computer to be tested, the method in this embodiment requires that the computer support a computer with dual hard disks or multiple hard disks, and preferably associates with ThinkPad P70 notebook computers in this embodiment. And the SSD to be tested needs the SSD supporting PCIe and NVMe protocols.

The software requirements include: operating system, Windows 10 operating system. Test software, microsoft devcon tool (available for free download from microsoft official website). Test scripts, self-written batch test scripts.

In one embodiment, after the step of detecting whether the SSD to be tested has been successfully disabled, the method further includes: and if the SSD to be tested is not forbidden successfully, stopping testing and reporting an error.

In one embodiment, after the step of detecting whether the SSD to be tested has been enabled successfully after the delay, the method further includes: if the SSD to be tested is not started successfully, the test is stopped and an error is reported.

In one embodiment, as shown in fig. 2, a method for testing the reset of the SSD controller is provided, where the method includes, before the step of obtaining the hardware identifier of the SSD controller to be tested by the devcon tool:

step 202, after the SSD to be tested is accessed as a slave disk to the test host, obtaining a test request for resetting the SSD controller;

and step 204, running the batch processing script according to the test request, and performing a cycle controller reset test on the SSD to be tested.

The specific test flow shown by referring to fig. 3 in combination includes the following steps:

firstly, taking the SSD to be tested as a slave disk, and accessing the SSD to be tested into a test host. And then, running the written batch processing script, and carrying out a circular Controller Reset test on the SSD to be tested.

The operation flow of the batch script is as follows:

1) the devcon tool obtains a HardWare identifier (HardWare Identifiers, HW Id for short) of a Standard NVMe Storage Controller of the SSD to be tested.

2) According to the HW Id, the devcon tool "disables" the Standard NVMe Storage Controller. This operation corresponds to issuing a power down Notification (Shutdown Notification) command to the SSD to be tested. And checking whether the SSD to be tested is disabled successfully, if so, continuing to execute the script, otherwise, reporting an error by the script, and stopping testing.

3) The devcon tool "enables" the Standard NVMe Storage Controller. This operation is equivalent to performing a Controller Reset test on the SSD to be tested. And after delaying for 1s, checking whether the SSD to be tested is successfully started, if so, continuing to execute the script, otherwise, reporting an error by the script, and stopping testing.

4) And (5) repeating the steps 2) to 3) for N times, wherein the value of N can be determined according to actual conditions.

In the embodiment, the purpose of performing high-frequency (only 1-2 s for each test time) Controller Reset test on the SSD can be realized by writing the batch processing script by using the free tool devcon without purchasing additional test software, so that the test cost is greatly reduced, the test time is greatly shortened, and the whole development period of the SSD product is favorably controlled.
