A hard disk access method is disclosed. The hard disk access method includes the following steps. A port mapping table is established in the execution of a startup process. An access instruction for accessing a target hard disk is received. A target slot of a target back plate, which the target hard disk is plugged in, is obtained according to a target-hard-disk-identification number of the target hard disk. According to the target-hard-disk-identification number of the target hard disk, the port mapping table is inquired to obtain a target port, which the target back plate is connected with. The target hard disk plugged in the target slot of the target back plate is accessed through the target port.
