Abstract:
1. A hot-plugging connector for a hard disk drive (HDD) comprising: an HDD plugging port; a connection port for an SATA cable and a power supply; a first diode based indicator having a positive terminal that is supplied power from a host computer and a negative terminal that is connected to a pin of said connector that is in connection with a plugging grounding line of said HDD but is not in direct connection with a grounding line of said host computer; and a second diode based indicator having a negative terminal that is connected to a pin of said connector that is in connection with an operation line of plugging of said HDD but is not in direct connection with a grounding line of said host computer; and each of said first and second diode based indicators having a positive terminal that is selectively connected with a voltage division resistor; wherein when said HDD is plugged, said negative terminal of said first diode based indicator is connected to said pin of said connector and said grounding line of said plugged HDD and then grounded so as to form a closed loop thereby lighting said first diode based indicator to show that said HDD is properly installed or plugged; when said HDD is set in operation, said second diode based connector is lit to show that said HDD is under normal operation.
