The present invention provides a hard disk type detecting circuit for detecting a type of a hard disk plugged into a hard disk connecting port. The circuit includes a ground end, a power end for receiving a reference power source, and a voltage divider having a first resistor and a second resistor electrically connected to the first resistor via a signal output end. Two paths are formed in the signal output end, one path being used as a signal output end, the other electrically connecting with an idle pin of the hard disk connecting port. When a hard disk is plugged into the hard disk connecting port, the idle pin, depending on the type of the plugged hard disk, is or is not electrically connected to the hard disk. According to the connection result, the signal output end outputs an identifiable signal, indicating the type of the hard disk.
