Abstract

A disk remapping method and apparatus, and an electronic device. The disk remapping method comprises: when a bad track exists in a thermal data area of a disk, determining a cold data area as a target area after data of an area in which the bad track is located are recovered to a reserved area of the disk in a manner of remapping using a redundant mechanism of redundant arrays of inexpensive disks (RAID) (S101); and exchanging the stored data in the reserved area and the target area to realize the accessing of the thermal data through a physical address of the target area (S102). The thermal data access is realized by directly accessing an original cold data area, thereby guaranteeing the read-write performance of a disk; and at the same time, the probability of bad track diffusion is reduced, and the reliability of a storage system is increased.

Description

technical field [0001] Embodiments of the present invention relate to information storage technology, and in particular to a disk remapping method, device and electronic equipment. Background technique [0002] Since hard disks use magnetic media to store information, hard disk bad sectors are a common problem in information storage. Among them, bad sectors include hard disk magnetic media damage and hard disk logic errors. When a member disk in a traditional redundant array of independent disks (Redundant Arrays of Inexpensive Disks, referred to as: RAID) has a bad track, the recovered data is written into the reserved area of ​​the disk through RAID technology; Address remapping (Remap) table, therefore, if subsequently accessing this bad track area, will first query the address remapping table to obtain the physical address of the above-mentioned recovered data in the disk reserved area, and then access the data corresponding to the physical address. [0003] Restoring ...
