METHOD FOR INDICATING STATUS OF A STORAGE DEVICE
First Claim
1. A method for indicating a status of a storage device, the method to be implemented by a complex programmable logic device (CPLD) that is coupled to a connector adapted for connection with the storage device (1), and to a visual indicator corresponding to the storage device, the method comprising:
- in response to receipt of a signal set from the connector, where the signal set includes an activity signal, a first signal that relates to whether the connector is connected with a storage device and that is used for distinguishing whether an interface of the storage device is of a certain type, a second signal that relates to whether the connector is connected with a storage device, and a third signal that relates to whether the connector is connected with a storage device and that is used for distinguishing between types of interfaces of storage devices other than the certain type, determining whether the connector is connected with a storage device based on the first signal, the second signal and the third signal;
when it is determined that the connector is connected with a storage device, identifying the storage device based on the first signal and the third signal;
operating in a mode corresponding to a result of identification of the storage device;
when operating in the mode corresponding to the result of identification of the storage device, generating a determination result representing an operating status of the storage device based on the activity signal; and
based on the determination result, outputting a control signal corresponding to the determination result to the visual indicator for driving the visual indicator to indicate the operating status of the storage device.

Abstract
A method for indicating a status of a storage device to be implemented by a complex programmable logic device (CPLD) is provided. The CPLD is coupled to a connector for connection with the storage device, and to an LED. The method includes: in response to receipt of a signal set from a connector, determining whether the connector is connected with a storage device based on the signal set; when affirmative, identifying the storage device based on the signal set; operating in a mode corresponding to a result of identification; generating a determination result representing an operating status of the storage device based on the signal set; and outputting a control signal corresponding to the determination result to the LED.
