Fig. 6 schematically shows a flowchart of a method for detecting a hard disk installation structure according to an embodiment of the present disclosure.

As shown in FIG. 6, an embodiment of the present disclosure provides a detection method for a hard disk installation structure, including:

Operation S61: Detect the voltage of at least one pin of the hard disk through the hard disk interface.

Operation S62: Outputting a prompt signal according to the detection result.

According to the embodiments of the present disclosure, when the user maintains or replaces the hard disk, it is necessary to pull out the hard disk installation structure, put the hard disk into the tray, and then push the tray into the hard disk installation structure to connect with the hard disk interface. Usually after the installation is completed, it is necessary to inspect the installation structure of the hard disk to check whether the pins of the hard disk and the hard disk interface are in good contact and whether signal transmission can be realized. Specifically, the voltage of at least one pin of the hard disk is detected through the hard disk interface. If the detection result shows that the pin voltage of the hard disk is low potential, the electronic device will send a prompt signal to remind the user that the hard disk and the hard disk interface can carry out signal transmission. .

FIG. 7 schematically shows a schematic diagram of detecting the voltage of a hard disk pin according to an embodiment of the present disclosure.

As shown in FIG. 7 , according to the embodiment of the present disclosure, the hard disk interface GPIO1 is connected to the pin 1 of the hard disk, and the hard disk interface GPIO2 is connected to the pin 18 of the hard disk. GPIO1 is the power interface for supplying voltage to the hard disk, and GPIO2 is the signal source interface to realize the signal transmission between the hard disk and the outside. By detecting the voltage of pin 1 and pin 18 of the hard disk, it can be judged whether the electrical connection between the hard disk and the hard disk interface is good.

The detection device EC detects that pin 1 and pin 18 of the hard disk are at low potential at the same time, indicating that all pins of the hard disk are plugged into the hard disk interface. At this time, the power indicator of the electronic device is automatically turned on and flashes for about 5 seconds to remind the user The electrical connection between the hard disk and the hard disk interface is good, and the sound of the buzzer can also remind the user that the electrical connection between the hard disk and the hard disk interface is good.

According to the embodiment of the present disclosure, to detect whether the electrical connection between the hard disk and the hard disk interface is good, it is also possible to check whether the storage space has been increased on the original basis by powering on the electronic device, and then opening the storage space of the electronic device. If it increases, then It indicates that the electrical connection between the hard disk and the hard disk interface is good. If there is no increase, it indicates that there is a problem with the electrical connection between the hard disk and the hard disk interface, and it is recommended to reinstall.

By implementing the detection method of the present disclosure, the user can quickly detect the installation status of the hard disk, that is, whether the electrical connection between the hard disk and the hard disk interface is good. This method is simple to operate and can save time for users.

According to an embodiment of the present disclosure, in the method, at least one pin of the hard disk includes at least one power supply pin and at least one signal pin.

According to an embodiment of the present disclosure, at least one of the pins includes a power pin, which makes the detection result unable to accurately determine the installation condition of the hard disk. For example, when the detection device EC detects that the voltage of the power pin is at a low potential, it cannot indicate that the electrical connection between the hard disk and the hard disk interface is good, because in this case the state of the signal pin voltage is not known, so when detecting At least one power supply pin and one signal pin are included, so as to realize the accuracy of detecting the installation condition of the hard disk.

According to an embodiment of the present disclosure, at least one pin of the hard disk includes at least an outermost pin of the hard disk.

According to an embodiment of the present disclosure, the hard disk pins include power supply pins and signal source pins, wherein the number of power supply pins is ten, and the number of signal source pins is also ten. If when detecting the installation situation of the hard disk, judge whether the electrical connection between the hard disk and the hard disk interface is good by detecting the voltage status of all the pins of the hard disk, it is too time-consuming and a waste of resources to detect in this way. Therefore, the outermost pin is selected from the 10 pins of the power supply and the outermost pin is also selected from the 10 pins of the signal source, and the electrical connection between the hard disk and the hard disk interface is judged by detecting these two outermost pins. good. Through detection in this way, the user saves time and does not waste resources.

According to an embodiment of the present disclosure, the operation S62 outputting a prompt signal according to the detection result may include outputting a different prompt signal according to whether the hard disk has a good electrical connection with the hard disk interface, and may also include outputting a prompt signal in a different sound mode and/or according to different detection results. Prompt signals in different light signal modes and/or output signals in different combination modes of sound and light signals, or a combination of the two, etc., but not limited thereto.

According to the state of the voltage of the power supply pin and the signal source pin detected in operation S61, it is determined to output different prompt signals. For example, if the voltage of the power supply pin and the signal source pin are detected to be at low potential, the output prompt signal can be the light prompt signal from the power indicator light, or the sound prompt signal from the buzzer, or it can be sent by The combination of the light signal from the power indicator light and the combination of sound quotes from the buzzer and so on, but not limited thereto.

According to the embodiments of the present disclosure, the user can know whether the hard disk has a good electrical connection with the hard disk interface by observing the prompt signal. In this way, the detection results are presented without user operation, only observation is required.
