Embodiment Construction

[0022] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0023] Such as figure 1 As shown, this embodiment provides an electronic device 1, including: at least one processor 11 and a memory 12, figure 1 Take a processor as an example. The processor 11 and the memory 12 are connected through the bus 10 , the memory 12 stores instructions executable by the processor 11 , and the instructions are executed by the processor 11 .

[0024] In an embodiment, the electronic device 1 can perform error correction checks according to the acquired original data, so that other parts of the original data are aligned and consistent with the data of an error correction unit. The error correction unit can be set according to the total length of the data segment. In one embodiment, a data bit and a parity bit form the error correction unit.

[0025] see figure 2 , whic...

Abstract

The invention provides a hard disk data error correction method and device, electronic equipment and a storage medium. The method comprises the steps of obtaining original data; judging whether the original data is misplaced or not according to a preset data bit verification condition; and if the original data is misplaced, modifying the original data to generate correction data according to the misplaced byte number corresponding to the original data. According to the method and device, the problem that in some scenes, DQS (Data Station Signal) is interfered is solved, so that the overall reliability of the solid state disk is improved.

Description

technical field [0001] The present application relates to the field of computer data storage, in particular, to a hard disk data error correction method, device, electronic equipment and storage medium. Background technique [0002] At present, solid-state drives are widely used in various scenarios, including some harsh environments, such as high and low temperature, electromagnetic radiation, and static electricity. In some cases, the transmission signal between the SSD master and Nand Flash (and non-flash memory) may be interfered, which poses a threat to the transmitted data, and may cause errors in the transmitted data, resulting in data loss. Of course, the current solution has also taken some preventive measures against various interferences, such as differential signals, filter circuits, electrostatic shields, etc. The prior art solves such problems through RAID (Redundant Arrays of Independent Disks, disk array), but the RAID parity (parity bit) itself needs to occ...
