12. A control method, for controlling at least one storage device, comprising:
detecting that an abnormal read-write operation is performed on the at least one storage device, and generating an abnormal signal correspondingly;
providing a first setting signal by a first controller in response to the abnormal signal;
generating a first state signal having a first logic value and latching the first state signal by a determining circuit in response to the first setting signal;
providing a first control signal in response to the first state signal having the first logic value;
disabling the at least one storage device on which the abnormal read-write operation is performed by a second controller in response to the first control signal;
operating a restart input module to convert the first logic value of the first state signal latched in the determining circuit into a second logic value;
providing a second control signal by the determining circuit in response to the first state signal having the second logic value; and
restarting the at least one storage device on which the abnormal read-write operation is performed by the second controller in response to the second control signal.
