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,...

Embodiment Construction

[0047] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

[0048] In the existing method for increasing the service life of a hard disk, the status of each sector in each mechanical hard disk can be obtained, and whether it is in a faulty sector can be determined, and if the number of faulty sectors is less than a preset value, it is a fault The sector sets the fault flag, triggers the faulty sector repair operation, and isolates the faulty sector from other sectors in the same mechanical hard disk. When a data read / write request located in the faulty sector is received, an error reminder message is issued. It can effectively reduce th...
