Problems solved by technology

However, negative samples are harder to find because it involves "bad" hard drives
After all, bad hard disks are limited, so when the hard disk failure prediction is carried out through the above method, the problem of inaccurate prediction often occurs
[0004] For the above problems, no effective solution has been proposed

Abstract

The present application provides a hard disk failure prediction method and device, which relate to the technical field of computers. The method includes: reading the SMART attribute data of the hard disk to be detected according to a first preset time interval, wherein the SMART attribute data includes at least An attribute parameter; determine whether the SMART attribute data meets the negative sample write condition based on the attribute parameter, wherein the negative sample is used to indicate that the hard disk to be detected is in an abnormal operating state; when it is determined that the negative sample write condition is satisfied, the The SMART attribute data is written into the negative sample array to predict the fault status of the hard disk to be detected through the negative sample array. This application alleviates the technical problem of low prediction accuracy when using the prior art to predict the hard disk fault.

Description

technical field [0001] The present application relates to the technical field of computers, in particular to a method and device for predicting hard disk failures. Background technique [0002] A hard disk is one of the main storage media of a computer, consisting of one or more aluminum or glass discs. Hard disk failures are divided into hardware failures and software failures, where software failures can be resolved by restarting or reinstalling the system. Hardware failures can be caused by the system, and hardware failures can also be failures of the hard disk itself, such as bad sectors, damaged partition tables, and viruses. [0003] Since the hard disk carries the task of data storage in the computer, when a hardware failure occurs in the hard disk, it is very likely that the hard disk cannot perform data recovery operations, resulting in data loss. Therefore, the prediction of hard disk failure is particularly important. In the prior art, the failure prediction me...
