Hard disk identification method and system, storage medium and computer equipment

The invention discloses a hard disk identification method, a hard disk identification system, computer equipment and a storage medium, and one embodiment provides a hard disk identification method which is applied to a controller and comprises the following steps: identifying a hard disk type of a to-be-accessed hard disk in response to a received external signal; determining interface information according to the hard disk type and a preset hard disk interface comparison table, wherein the hard disk interface comparison table comprises the hard disk type and the interface information corresponding to the hard disk type; and in response to the access of the to-be-accessed hard disk, setting a hard disk interface according to the interface information. According to the hard disk identification method provided by the invention, the problems that the physical forms of U.2 and U.3 interfaces of the existing hard disk are consistent and the definitions of signal interfaces are different are solved, the hard disk s
