Problems solved by technology
[0004] In view of this, the embodiment of the present disclosure proposes a configuration method, device, and storage medium for a hidden partition of a solid-state hard disk to solve the following problems in the prior art: the hidden partition of the NVMe SSD is divided by a third-party tool, and after division, the hidden partition is hidden. The partition is invisible to the user under the OS, but it can be seen by the user in the disk management. The user knows all the contents of the hidden partition, and the hidden function of the hidden partition is poor.

The embodiment of the invention provides a configuration method and device for a hidden partition of a solid state disk and a storage medium, and the method comprises the steps that under the condition that the solid state disk receives a preset control instruction, a preset interface is presented on a first preset interface, and a firmware architecture of the solid state disk supports namespace management; a namespace management command is received through a predetermined interface, each field of a data structure of firmware is created, a hidden partition taking LBA0 as an initial address comprises a first partition and a second partition, the initial address of the first partition is LBA0, the first partition is configured to be visible when a first predetermined instruction is received, and the second partition is configured to be visible when a second predetermined instruction is received. The start address of the second partition is adjacent to the end address of the first partition, and the second partition is configured to be visible when a first predetermined instruction from the predetermined interface is received. According to the embodiment of the invention, the second partition cannot be seen in OS or disk management, a common user cannot know the existence of the second partition, and the hiding function is relatively good.
Description
technical field [0001] The present disclosure relates to the field of data processing, and in particular, to a configuration method, device and storage medium for a hidden partition of a solid-state hard disk. Background technique [0002] The existing HPA (which is the standard of ATA) is the standard in the ATA (Advanced Technology Attachment) protocol. SATA SSD (solid state drive) / HDD (traditional hard disk, the most basic computer memory) supports the ATA protocol and can use HPA Technology to achieve hidden partition division. [0003] However, the NVMe (Non-Volatile Memory Host Controller Interface Specification, NVM Express) protocol does not support ATA commands and does not support HPA functions, so the hidden partitions of existing NVMe SSDs are divided by third-party tools. After the partition, the hidden partition is invisible to the user under the OS (operating system), but can be seen by the user in the disk management. The user knows all the contents of the h...
