Embodiment Construction

[0083] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0084] Before explaining the storage medium management method provided by the embodiment of the present application in detail, the relevant terms and execution subjects involved in the embodiment of the present application are firstly introduced.

[0085] First, a brief introduction is given to relevant terms involved in the embodiments of the present application.

[0086] NAND Flash: NAND Flash can be used as a storage medium for storage. Generally, NAND Flash uses a three-terminal device as a storage unit, and the three-terminal device includes a source, a drain, and a floating gate. Wherein, the floating gate can be used to store electrons, and there is an insulating layer around the floating gate, which can protect the electr...

Abstract

The invention discloses a storage medium management method and device and equipment, and belongs to the technical field of data storage. The method comprises the following steps: according to current storage medium parameters of a to-be-managed storage medium, determining the service life state of the storage medium, namely determining the wear degree of the current storage medium; when the service life state of the storage medium is determined to be in the end of the service life, meaning the current storage medium is high in abrasion degree and possibly cannot work normally. Data stored in the storage medium has the risk of losing, so that write-in control can be conducted on the storage medium, the data size written into the storage medium is reduced, or user write-in is forbidden. Therefore, further abrasion of the storage medium is avoided, and data stored in the storage medium is protected.

Description

technical field [0001] The present application relates to the technical field of data storage, and in particular to a storage medium management method, device and equipment. Background technique [0002] With the development of data storage technology, the storage medium has been widely used, and the storage medium can use NAND Flash (Not And Flash, and non-flash memory) for storage. As the user writes / erases more data, the wear of NAND Flash gradually increases, which will eventually cause the storage medium to fail to work normally. In this case, the data stored in the storage medium is at risk of being lost. [0003] At present, the life value of the storage medium is usually detected. When it is detected that the life value of the storage medium is less than the set threshold, it indicates that the data in the current storage medium may be at risk of loss. In this way, an alarm message can be sent to the user. To remind the user to back up the data stored in the storage...
