Abstract
A system and method, which correctly and easily diagnose all types of failures generated in a disc drive, the system includes an interface, a system controller, a failure type diagnosis unit, and an output unit. The interface transmits an operation state information request signal to the disc drive and receives operation state information from the disc drive. The system controller transmits the operation state information request signal to the interface and generates a failure information file using the operation state information when the operation state information is received from the interface. The failure type diagnosis unit analyzes the failure information file generated by the system controller to diagnose the type of failure of the disc drive. The output unit outputs the result of the diagnosis of the type of failure under the control of the system controller.
