Abstract

The invention provides a method for prolonging the service life of a mechanical hard disk, a storage device and a system.The method comprises the steps that the state of each sector in each mechanical hard disk is obtained, and whether a fault sector exists in the mechanical hard disk or not is determined according to the state of each sector; if the number of the faulty sectors in the mechanical hard disk is smaller than a set value, fault identifiers are set for the faulty sectors, and the faulty sectors are isolated from other sectors in the same mechanical hard disk; when a data read-write request is received, determining whether data corresponding to the data read-write request is located in the fault sector; if the data corresponding to the data read-write request is located in the fault sector, error reminding information is sent out. According to the scheme, the data read-write performance is guaranteed. Meanwhile, the probability that the mechanical hard disk is removed is reduced, and the service life of the mechanical hard disk is prolonged.

Description

technical field [0001] The present application relates to the technical field of information processing, and in particular, relates to a method, storage device and system for increasing the service life of a mechanical hard disk. Background technique [0002] With the development of hard disk technology, the capacity of mechanical hard disks is increasing year by year. In the actual operating environment, mechanical hard disks may have the following problems: mechanical failure, resulting in inaccessibility of the entire disk; or abnormal magnetic media, resulting in read and write errors or slow response . [0003] For mechanical failures, the mechanical hard disk can only be removed to perform data recovery on the entire disk. For magnetic media abnormalities, the manifestations may be as follows: [0004] (1) Sector error, resulting in reading IO error; (2) Sector error, resulting in bad block remapping when data is written; (3) Sector ECC check error, resulting in mult...
