Patent ID: 7921332

Claim:
A failure diagnostic system for a disc drive, comprising: an interface transmitting an operation state information request signal to the disc drive and receiving operation state information from the disc drive; a system controller transmitting the operation state information request signal through the interface to the disc drive and converting the operation state information received through the interface into a failure information file using a method of converting data into a file; a failure type diagnosis analyzer analyzing the failure information file generated by the system controller to diagnose a type of failure in the disc drive; and an output unit outputting a result of the diagnosis of the type of failure according to the system controller, wherein the failure type diagnosis analyzer compares previously stored failure type diagnosis information including a first group of codes with the generated failure information file, which includes a second group of codes, and when the first group of codes and the second group of codes are detected as not being identical to each other, judges that a failure is generated in an operation of the disc drive corresponding to the detected non-identical codes.
