DETECTING SYSTEM FOR HARD DISK DRIVE

摘要

A detecting circuit for a hard disk drive includes a controller, a first connector, a second connector connected to the first connector, a processor, a feedback circuit, and an indicator circuit. The controller outputs a control signal to the indicator circuit upon receiving feedback data from the feedback circuit, to control the indicator circuit to send out an indicator message. The processor determines whether a connection between the first and second connectors or the hard disk drive is the cause of a malfunction depending on the indicator message sent out by the indicator circuit.

1. A detecting system, comprising:
a hard disk drive (HDD), comprising:
a first connector comprising at least one data sending pin and at least one data receiving pin;a controller connected to the first connector;an indicator circuit; anda feedback circuit;wherein when the HDD is in a normal status, the controller outputs first commands to the feedback circuit through the at least one data sending pin, the feedback circuit outputs feedback data to the controller through the at least one data receiving pin, upon receiving the first commands, the controller outputs a control signal to the indicator circuit when the controller receives the feedback data, to control the indicator circuit to send out an indicator message; and a motherboard, comprising:
a second connector connected to the first connector, wherein the second connector comprises at least one data sending pin and at least on data receiving pin, the data receiving pin of the first connector is coupled to the data receiving pin of the second connector, the data sending pin of the first connector is coupled to the data sending pin of the second connector; anda processor configured to perform a test on the HDD, wherein the processor outputs second commands to the controller through the second and first connectors, the controller outputs a state signal upon receiving the second commands; wherein a connection error is indicated between the first and second connectors when the processor does not receive the state signal, and the indicator circuit sends out the indicator message; and malfunction of the HDD is indicated when the indicator circuit does not send out the indicator message.
