Referring to fig. 7, fig. 7 is a flowchart of a method for detecting abnormal power failure of a hard disk according to another embodiment of the present invention, where the method includes, but is not limited to, steps S701 to S703.
Step S701: formatting the hard disk to be tested;
step S702: shielding the address of the hard disk to be tested based on a preset shielding parameter to form a third shielding area and a third testing area;
step S703: and sending a test instruction to the hard disk to be tested, and carrying out power-down test on the hard disk to be tested until the parameters of the hard disk to be tested meet preset hard disk parameters.
In some embodiments, after the test is performed on the hard disk to be tested again, formatting operation is performed on the hard disk to be tested, data filled in the hard disk to be tested is removed, the second shielding area or the second test area is divided, and the like, the hard disk to be tested is shielded again based on the shielding parameters to form a third shielding area and a third test area, repeated test on the hard disk to be tested is achieved, the situation that data are omitted in the test process is avoided, the test precision of the hard disk to be tested is further improved, finally, a test instruction is sent to the hard disk to be tested, and the power-down test is performed on the hard disk to be tested until the parameters of the hard disk to be tested meet preset hard disk parameters, so that the test process can be verified, and the test precision is improved.
It should be noted that the hard disk parameters include, but are not limited to, a power management parameter, a data protection parameter, and the like, where the power management parameter is a power management policy of the hard disk in a power failure situation, and the parameters include a power mode, a power management level, a power management time, and the like of the hard disk. In the power failure test, attention is paid to the setting of these parameters to ensure that the hard disk can correctly store data in the case of power failure; the data protection parameter is a data protection strategy of the hard disk under the condition of power failure. These parameters include caching policies of the hard disk, write policies, verification policies, etc. In a power down test, the validity of these parameters needs to be tested to ensure that the hard disk is able to properly protect the data in the event of a power down.
