Abstract

The embodiment of the present invention discloses a disk management method, device, and storage medium. The method includes: determining the starting position of cleaning the disk and the writing start position of data writing to the disk; counting the number of data in the area to be recovered The amount of data, the area to be recovered is the area between the cleaning start position and the writing start position; when the data amount meets the set threshold value, the recovery process is performed on the area to be recovered , and record the end position of the area to be recovered after recovery processing as the updated starting position for cleaning. Through the technical solution of the embodiment of the present invention, the problem of out-of-order operation of disk blocks can be solved, and the jumping back and forth of the magnetic head can be effectively avoided.

Description

technical field [0001] The invention relates to disk management technology, in particular to a disk management method, device and storage medium. Background technique [0002] For traditional mechanical disks, its read and write operations rely on the mechanical rotation of the disk and the movement of the head to locate the data position. For random operations such as random read and write, the head needs to constantly adjust the position of the track to read and write data at different positions. As a result, the movement of the magnetic head is very frequent, which seriously affects the efficiency of data reading and writing. Therefore, a solution to change the random operation of the disk to sequential operation has appeared. [0003] When converting random operations into sequential operations on the disk, the space on the disk will be excessively occupied invalidly. The common method of disk recovery is: organize all blocks on the disk in the form of a linked list or i...
