Hard disk safety freezing locking method and related equipment

The invention discloses a hard disk safety freezing locking method and device, electronic equipment and a computer readable storage medium. The hard disk safety freezing locking method comprises the steps that in the startup process, the level state of a preset GPIO interface of an integrated south bridge is detected through a BIOS; the preset GPIO interface is connected with a jump cap circuit used for setting the level state of the preset GPIO interface; a judgment is made whether the level state is a first preset level state or not through a BIOS; and if yes, security freezing locking operation is executed on the corresponding target hard disk through the BIOS. The hardware circuit design and the BIOS program design on the integrated south bridge, namely the PCH, are combined to realizethe safe freezing and locking of the target hard disk; a user only needs to manually set the connection position of the jump cap in the jump cap circuit to complete the setting of the safety freezinglocking, and then the set
