1. A hard disk status testing apparatus, comprising a voltage reading module, a controller, an analogue switch, and multiple hard disk slot units, wherein each hard disk slot unit of the multiple hard disk slot units comprises:
a hard disk status testing module and a hard disk status indication module, wherein the hard disk status testing module comprises: a first presence testing terminal, a second presence testing terminal, an activity status testing terminal, a pull-up resistor, a first testing resistor, a second testing resistor, and a third testing resistor; the first presence testing terminal is connected to a first end of the first testing resistor; a first path of a second end of the first testing resistor is connected to a power supply through the pull-up resistor, and a second path of the second end of the first testing resistor is connected to an input end of the analogue switch; the second presence testing terminal is connected to a first end of the second testing resistor; a first path of a second end of the second testing resistor is connected to the power supply through the pull-up resistor, and a second path of the second end of the second testing resistor is connected to the input end of the analogue switch; the activity status testing terminal is connected to a first end of the third testing resistor; a first path of a second end of the third testing resistor is connected to the power supply through the pull-up resistor, and a second path of the second end of the third testing resistor is connected to the input end of the analogue switch; a testing output end of each hard disk status testing module is connected to the input end of the analogue switch; an output end of the analogue switch is connected to an input end of the voltage reading module; a control input end of each hard disk status indication module is connected to a control output end of the controller; and the hard disk status testing modules and the hard disk status indication modules among different hard disk slot units of the multiple hard disk slot units are time-multiplexed, achieving independent control of the hard disk status testing modules among the different hard disk slot units and independent control of the hard disk status indication modules among the different hard disk slot units.
