The application aims to provide a method and device for hot loading a disk filter drive. Specifically, the method comprises: determining a corresponding disk drive of a to-be-protected disk; obtaining a first entry address of a write request processing module in the disk drive; replacing the write request processing module in the first entry address with a write request forwarding processing module; and forwarding a received write request on the disk to the corresponding disk filter drive through the write request forwarding processing module to perform processing. Compared with the prior art, the method has the characteristics that the address of the write request processing module between the to-be-protected disk and the corresponding disk drive is determined, the write request processing module in the address is replaced with the write request forwarding processing module, and the received write request on the disk is forwarded to the corresponding disk filter drive through the write request forwarding processing module to perform processing, so that the purpose of hot loading the disk drive is achieved, the operational stability of the protected disk is kept, and the manual operation and maintenance costs are reduced.
