Problems solved by technology

After such physical damage, the existing data on the disk cannot be recovered, but at the same time, the service life of the disk is over, which directly leads to the failure of the hard disk to fully utilize its full service life, thus increasing the maintenance cost of the data center

Embodiment Construction

[0042]Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0043] The computer equipment includes user equipment and network equipment. Wherein, the user equipment includes but is not limited to computers, smart phones, PDAs, etc.; the network equipment includes but is not limited to a single network server, a server group composed of multiple network servers, or a large number of computers or A cloud composed of netwo...

Abstract

The invention provides a hard disk data wiping method, a hard disk data wiping server and a hard disk data wiping system. The method comprises the steps of sending a data write-in command to disk cluster equipment; writing first type of data into a plurality of hard disks mounted in a disk cluster by means of the data write-in command so as to overwrite the original data. The hard disk data wiping method, the hard disk data wiping server and the hard disk data wiping system can be used for efficiently wiping data in a nondestructive way.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a hard disk data erasing method, server and system. Background technique [0002] Mechanical hard drives (such as hard disk drives, Hard Disk Drive, HDD) and solid-state drives (Solid State Drive, SSD) are commonly used storage components in data centers, and both have their own advantages. For example, solid-state drives have advantages in terms of data reading speed, shock resistance, power consumption, operating sound, and heat generation; while mechanical hard drives have the advantages of large capacity and low price. [0003] For various reasons, storage components need to be taken out of the data center. In view of data security and related regulations, the data carried on the storage component must be effectively destroyed before being taken out of the data center to avoid data leakage. In addition, in the case of failure replacement, relocation, etc., data also needs...
