Method and device for prolonging service life of hard disk, computer equipment and storage medium

Abstract

The invention relates to a method and device for prolonging the service life of a hard disk, computer equipment and a storage medium. The method comprises the following steps: acquiring fault information, determining a fault sector according to the fault information, and identifying a sector number of the fault sector; judging the sector type of the fault sector according to the sector number; and if the sector type is a first type of sector, performing sector repair on the fault sector by using a standby sector. By adopting the method, the problem that the hard disk is eliminated in advance due to unreasonable distribution of the standby sectors when the standby sectors of the hard disk are used for repairing the fault sectors can be solved.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular, to a method, apparatus, computer equipment and storage medium for extending the life of a hard disk. Background technique [0002] During the use of a hard disk, faulty sectors are often affected by device aging or environmental factors. When sending a data read / write request to the hard disk, if the sector corresponding to the read / write request is a faulty sector, normal read / write operations cannot be performed, and an alarm message indicating read / write failure will be returned directly. [0003] In order to solve the problem of inability to read and write after the faulty sector is damaged, hard disk manufacturers usually pre-set a small number of spare sectors during hard disk production. It is mapped to an unused spare sector, and the spare sector replaces the faulty sector for data request processing. However, when the spare sector is used up,...

AI Technical Summary

Problems solved by technology

However, when the spare sectors are used up, if a faulty sector occurs again, it will always return read and write failure. When there are too many faulty sectors that cannot be remapped, the hard disk will be unusable

Furthermore, even if there are only a small number of faulty sectors that cannot be remapped, the hard disk will be unusable if the faulty sectors store and process key data, and thus cause the hard disk to be eliminated in advance

[0004] In the related technology, when using the spare sector of the hard disk to repair the faulty sector, the hard disk is eliminated in advance due to the unreasonable allocation of the spare sector, and no effective solution has been proposed yet.
