Further, the main purpose of performing power failure test on the storage device is to verify the capability of the storage device in data processing and protection when abnormal power failure occurs, so that comparison and verification of data before and after power failure are very important. For accurate data verification, the data processing state of the storage device before power failure can be determined, and for example, when the data is powered down during writing and the data is powered down after writing, the expected storage data is completely different during verification. The conventional complete machine power failure test mode has the problem that the data can not be accurately checked. The present invention solves this problem by adding a data signal pin design on the test board. The following describes an execution process of a test program by powering down in a Programming state (Programming state) during test write data, and describes an execution process of a test program by powering down in a Programming state (Programming state) during test write data, referring to a flowchart of a third embodiment of a method for testing power down of a storage device shown in fig. 3, after the test program runs, first performing a full disk write operation on test equipment by using first feature data as background data, so as to prevent influence of uncertain data in the storage device to be tested on a subsequent data verification process. Then randomly selecting a data area A, writing second characteristic data, wherein the area A can be a plurality of discontinuous random areas, and the areas are marked by a mapping table of a test program. And then selecting the area B (which is not overlapped with the area A) as a power failure test area, and writing third characteristic data. During the writing process, and referring to fig. 5, the signal pin on the test board always detects the data storage status of the memory device under test. When the level of the signal pin changes from high to low, indicating that the tested storage device is in a Programming state (Programming state), the signal processing module informs the PMU module to control the PMU to cut off corresponding power supply according to a power-down strategy set in the test flow module, such as all power-down, only IO power supply loss or only controller power supply loss. And after the power supply is recovered, the test program starts to read the data of the tested storage equipment on the whole disk and checks the data. According to the area mapping relation recorded by the test program, the data of the area A should be the first characteristic data or the second characteristic data, the data of the area B should be the first characteristic data or the third characteristic data, and the data of the rest areas should be the first characteristic data. If new characteristic data are found, it is indicated that the storage device has a vulnerability to the capability of processing and protecting data when abnormal power failure occurs.
It should be understood that the above application Programming State (Programming State) is powered down to illustrate the execution process of the test program, and is not intended to limit the present invention, and as mentioned above, the power down test may also be performed for the Sending-data State (Sending-data State) and the receiving-data State (receiving-data State) of the memory.
