Locking and unlocking method of hard disk

Abstract

The invention discloses a locking and unlocking method of a hard disk. The method comprises the steps of judging whether the distance between an encryption lock hard disk and a hard disk secret key is within a first threshold value or not; if the hard disk key is within the first threshold value and the hard disk key sends an unlocking instruction to the encryption lock hard disk, unlocking the encryption lock hard disk and operating the lock normally, and allowing reading and writing; if the data is not within the first threshold value or the hard disk key sends a locking instruction to the encryption lock hard disk, locking the encryption lock hard disk, operating the protection program, and forbidding reading and writing. Opening of the encryption lock hard disk is determined only by the encryption lock hard disk and the hard disk key and is irrelevant to read-write equipment and a use system of the hard disk, so that the encryption lock hard disk is high in compatibility and wide in application range; the hard disk can run the protection program and leave the automatic running protection program at any time, so that the data security is ensured.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a method for locking and unlocking a hard disk. Background technique [0002] Existing data is mainly stored in mechanical hard drives or solid state drives. [0003] Most of the existing hard disks only have the function of storing data, and do not have the function of hard disk encryption and lock, which makes it easy to leak data, files and information in the hard disk during the process of repairing computers or losing hard disks. [0004] When the existing part computer is opened at every turn in its supporting complete machine, the hard disk password lock and the hard disk password are opened by the BIOS system. However, both the hard disk encryption lock and the opening of the hard disk lock need to be used with the matching motherboard and BIOS system. After the hard disk encryption lock, other read-write devices cannot use the hard disk, that is, the compatibility ...

AI Technical Summary

Problems solved by technology

However, both the hard disk encryption lock and the opening of the hard disk lock need to be used with the matching motherboard and BIOS system. After the hard disk encryption lock, other read-write devices cannot use the hard disk, that is, the compatibility is not strong; in addition, when the hard disk is successfully turned on to off During this period of time, anyone who has access to the hard disk computer can easily obtain the data, files and information in the hard disk
