Implementation method and device of host protection area and electronic equipment

Abstract

The invention relates to an implementation method and device for a host protection area and electronic equipment. The method comprises the following steps: obtaining a creation instruction of creatinga host protection area by a target storage unit based on a nonvolatile memory host controller interface specification protocol; and obtaining current attribute information of the target storage unit,and setting a host protection area in the target storage unit at least through an instruction defined based on a non-volatile memory host controller interface specification protocol standard under the condition that the attribute information indicates that the target storage unit does not include the host protection area. Thus, the invention provides an implementation scheme for creating a host protection area in a storage medium based on a nonvolatile memory host controller interface specification protocol. Based on the scheme, host protection area creation of the storage medium based on thenonvolatile memory host controller interface specification protocol can be supported, and the defect that in the prior art, the host protection area function cannot be achieved on the storage mediumbased on the nonvolatile memory host controller interface specification is overcome.

Description

technical field [0001] The present application belongs to the technical field of disk management, and in particular relates to a method, device and electronic equipment for realizing a host protection area. Background technique [0002] Host Protected Area is the abbreviation of Host Protected Area, which is a standard of ATA (Advanced Technology Attachment, high-tech configuration). Under this standard, it can support a part of the storage space on a specific storage device to be hidden as a host protected area. The divided storage space is invisible to upper layer software such as BIOS and OS, and theoretically can prevent viruses and prevent illegal access or loss of data after the storage device is stolen. Therefore, this part of the storage space can be used to back up the user's important data, or install some special applications, such as installing a specific application to take over the PC when the host operating system crashes, so as to restore the operating system...

AI Technical Summary

Problems solved by technology

[0003] However, the current host protection zone only supports storage devices based on the ATA protocol, such as SATA HDD and SATA SSD, and does not support storage devices based on the non-volatile memory host controller interface specification. Realize the host protection area function on the storage device with the controller interface specification (such as the PCIe non-volatile memory host controller interface specification SSD)
