[0062] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0063] In the description of this invention, it should be understood that the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0064] In the description of this invention, "several" means one or more, "multiple" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0065] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0066] This invention provides a hard disk and a method for its self-destruction. The hard disk includes a disk, a detection unit, a self-destruct mechanism, and a first control unit. The detection unit can be used to acquire the status information of the hard disk. The self-destruct mechanism includes a valve component, a reagent bottle, and a drive component connected in sequence. The reagent bottle is used to hold a self-destruct reagent. The first control unit is connected to both the detection unit and the valve component. The first control unit can receive status information from the detection unit and then control the valve component to open based on the status information, so that the drive component pushes the reagent bottle to discharge the self-destruct reagent to the disk. Therefore, in the event that a computer or hard disk is stolen or lost, the hard disk destruction function can be automatically activated to automatically destroy the disk containing information, making the data stored on the disk unrecoverable and preventing information leakage.

[0067] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0068] Reference Figure 1 and Figure 2 , Figure 1 and Figure 2 This is a schematic diagram of a hard disk provided in an embodiment of the present invention. The hard disk includes a disk 107, a detection unit 130, a self-destruct mechanism 120, and a first control unit 140. The detection unit 130 is used to acquire the status information of the hard disk. The self-destruct mechanism 120 includes a valve component 121, a reagent bottle 122, and a drive component 123 connected in sequence. The reagent bottle 122 is used to hold a self-destruct reagent. The first control unit 140 is connected to the detection unit 130 and the valve component 121 respectively.

[0069] In one embodiment, the hard disk may further include a housing 100, a spindle 104, a read / write head 105, a head parking area 106, a head arm 108, a voice coil motor 109, and a permanent magnet 110. The spindle 104 is used to fix the disk 107 in place. When the hard disk accesses data, the movement of the head arm 108 drives the read / write head 105 to the center position of a designated track and precisely tracks that track. When the hard disk is powered off, the read / write head 105 is pulled to the head parking area 106 to avoid damage to the surface of the disk 107. This also ensures that the read / write head 105 does not directly contact the disk 107. The read / write head 105 contacts the disk 107 during startup and is used to read and write data. The spindle motor (not shown in the figure) drives the disk 107 to rotate. The read / write head 105 is driven by the voice coil motor, and moves in an inward and outward arc along the diameter of the disk 107 with the voice coil motor 109 as the axis. In this way, through the rotation of the disk 107 and the inward and outward movement of the read / write head 105, the read / write head 105 can read and write to every position on the disk 107. No specific restrictions are made here.

[0070] In one embodiment, the first control unit 140 receives status information from the detection unit 130 and controls the valve component 121 to open according to the status information, causing the drive component 123 to push the reagent bottle 122 to discharge the self-destructing reagent to the disk 107, thereby causing the disk 107 to be automatically destroyed and the data stored in the disk 107 to be unrecoverable. Therefore, this embodiment of the invention can automatically activate the hard drive destruction function in the event that the computer or mechanical hard drive is stolen or lost, so that the disk 107 storing information in the mechanical hard drive is automatically destroyed and the data stored in the disk 107 cannot be recovered, thereby improving the security of hard drive data and preventing information leakage.

[0071] It should be noted that the self-destructing reagent can be sulfuric acid, hydrochloric acid, or a special destruction solution, or other reagents or ultrafine powders that can corrode or wear down the disk 107 and make the data in the disk 107 irrecoverable. No specific restrictions are made here.

[0072] It should be noted that there is no limit to the number of disks 107; it can be 1, 2, 4, or other numbers. No specific restrictions are imposed here.

[0073] It should also be noted that the valve component 121 can be installed on the side of the reagent bottle 122 (such as the left side and near the bottle opening of the reagent bottle 122), or in other locations, without specific restrictions.

[0074] It should also be noted that the reagent bottle 122 is connected to the valve component 121, and the self-destructing reagent in the reagent bottle 122 can flow from the reagent bottle 122 into the valve component 121.

[0075] It should be noted that a recess can be provided inside the hard disk, in which the valve component 121, reagent bottle 122 and drive component 123 are installed; or, the valve component 121, reagent bottle 122 and drive component 123 can also be installed outside the hard disk, as long as the nozzle outlet is inside the hard disk, and no specific restrictions are made here.

[0076] It should be noted that valve component 121 can be a solenoid valve, electric valve, electrically controlled valve, or pneumatically controlled valve, etc. Among them, the solenoid valve can be a gas solenoid valve, miniature solenoid valve, pulse solenoid valve, or DC solenoid valve, etc., without specific restrictions.

[0077] It should be noted that the first control unit 140 can be installed on the back of the hard drive casing, such as... Figure 2 As shown; the first control unit 140 can also be installed inside the hard disk housing 100, or in other locations, without specific limitations.

[0078] It should also be noted that the driving component 123 may include a motor and a transmission assembly, or it may be a linear motor, an accumulator, an air bag, a spring, or other driving components 123 that can drive the reagent bottle 122 to move. The motor may be a servo motor or a stepper motor, etc., and no specific limitation is made here.

[0079] In some implementations, the hard drive also includes an external communication port for connecting to external communication devices and communicating with the detection unit. Specifically, the detection unit can acquire the identification information of the external communication device; while the first control unit is used to control the valve component to open based on the identification information, causing the drive component to push the reagent bottle to discharge self-destructing reagent to the hard drive. This results in the automatic destruction of the hard drive containing the information, rendering the data on the hard drive unrecoverable and preventing information leakage.

[0080] It should be noted that the hard drive can identify external communication devices connected to it. Specifically, the detection unit acquires the identification information of the external communication device and sends it to the first control unit. The first control unit receives the identification information from the detection unit and compares it with the authorized identification information already stored on the hard drive. If the comparison is inconsistent, the first control unit controls the valve component to open, causing the drive component to push the reagent bottle to discharge self-destructing reagent to the disk, thereby automatically destroying the disk containing the information stored in the hard drive, making the data on the disk unrecoverable to prevent information leakage. Alternatively, if the comparison is consistent, the data exchange channel between the hard drive and the external communication device is opened, and the hard drive operates normally. During the normal operation of the hard drive, the detection unit acquires the status information of the hard drive in real time to ensure the security of the data on the disk.

[0081] It should be noted that identification information may include MAC address, device serial number or user information, etc., and no specific restrictions are made here.

[0082] It should be noted that the external communication device can be a hard drive or other terminal devices, such as mobile phones, tablets, laptops, handheld computers, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc. The embodiments of the present invention do not impose specific limitations.

[0083] In some implementations, the hard drive also includes an external self-destruct port, which is communicatively connected to a detection unit, and the first control unit is communicatively connected to a second control unit. Specifically, the detection unit is used to acquire self-destruct control information from the external self-destruct port; the first control unit is used to send the self-destruct control information to the second control unit, so that the second control unit controls the valve component to open according to the self-destruct control information, so that the drive component pushes the reagent bottle to discharge the self-destruct reagent to the disk, thereby causing the disk storing information in the mechanical hard drive to be automatically destroyed, and the data stored on the disk cannot be recovered, thus improving the security of hard drive data and preventing information leakage.

[0084] Specifically, the detection unit detects the external self-destruct port, obtains self-destruct control information, and sends this information to the first control unit. The first control unit then sends the received self-destruct control information to the second control unit. The second control unit analyzes the self-destruct control information. If the analysis indicates that the hard drive or the computer containing the hard drive is in an abnormal state, the second control unit can control the valve component to open, causing the drive component to push the reagent bottle to discharge the self-destruct reagent to the disk. This automatically destroys the disk containing the information stored in the hard drive, making the data unrecoverable and improving the security of the hard drive data to prevent information leakage. If the analysis indicates that the hard drive or the computer containing the hard drive is in a normal state, the hard drive operates normally. During normal operation, the detection unit acquires the hard drive's status information in real time, such as the self-destruct control information, to ensure the security of the data on the disk.

[0085] It should be noted that the hard drive can communicate with the second control unit via an external self-destruct port. The second control unit is a control unit independent of the hard drive. For example, the second control unit can be located in another hard drive, or in other components, functional circuits, integrated circuits, or chips in the terminal device. The terminal device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. The embodiments of the present invention do not impose specific limitations.

[0086] It should also be noted that the number of the second control unit is not limited; it can be one, two, four, or other numbers, and no specific restrictions are imposed here.

[0087] In addition, in some implementations, such as Figure 6 As shown, the hard disk also includes a power interface 103 and a data interface 102, both of which are communicatively connected to the detection unit. Specifically, the detection unit is used to acquire the first connection status information of the power interface 103 and the second connection status information of the data interface 102. The first control unit is specifically used to control the data access permissions of the hard disk according to the first connection status information and the second connection status information, respectively.

[0088] It should be noted that the first connection status information may be the connection status of the power cable connected to the power interface 103 of the hard drive, and the second connection status information may be the connection status of the data cable connected to the data interface 102 of the hard drive.

[0089] In an optional embodiment, when the first connection status information indicates that the power cable has been abnormally unplugged, the detection unit sends the first connection status information to the first control unit. The first control unit receives the first connection status information from the detection unit, records the first connection status information in the hard disk, and can control the data access permissions of the hard disk to be inaccessible. When the first connection status information indicates that the power cable is connected normally, the first control unit can control the data access permissions of the hard disk to be accessible. This embodiment of the invention does not impose specific limitations on this.

[0090] In an optional embodiment, when the second connection status information indicates that the data cable has been abnormally disconnected, the detection unit sends the second connection status information to the first control unit. The first control unit receives the second connection status information from the detection unit, records the second connection status information in the hard disk, and can control the data access permissions of the hard disk to be inaccessible. When the second connection status information indicates that the data cable is connected normally, the first control unit can control the data access permissions of the hard disk to be accessible. This embodiment of the invention does not impose specific limitations on this.

[0091] In addition, in some implementations, such as Figure 1 , Figure 4 and Figure 5 As shown, the self-destruct mechanism 120 includes a nozzle 124, which is connected to a valve component 121, and the valve component 121 is disposed between the nozzle 124 and the reagent bottle 122.

[0092] It should be noted that the nozzle 124 can be connected to the front end of the valve component 121, and the nozzle 124 communicates with the valve component 121, and the valve component 121 communicates with the reagent bottle 122. No specific restrictions are made here.

[0093] In an optional embodiment, the nozzle 124 is provided with an outlet 125 along the axial direction of the disk 107, and the outlet 125 faces the upper and lower surfaces of the disk 107. When the valve component 121 is opened, the driving component can push the reagent bottle 122 to discharge the self-destructing reagent from the reagent bottle 122. The reagent then flows through the valve component 121 and is finally sprayed from the outlet 125 of the nozzle 124 onto the upper and lower surfaces of the disk 107, so that the disk 107 storing information in the hard disk is automatically destroyed, and the data stored in the disk 107 cannot be recovered, thus preventing information leakage. This embodiment of the invention does not impose specific limitations on this. It should be noted that the number of outlets 125 is not limited; it can be one, two, three, or more, and all outlets 125 face the upper surface, lower surface, or both of the upper and lower surfaces of the disk 107. No specific limitations are imposed here. For example, when there are 3 nozzles 125 and 2 disks 107, the first nozzle 125 can be directly facing the upper surface of the first disk 107, the second nozzle 125 can be directly facing the lower surface of the first disk 107 and the upper surface of the second disk 107, and the third nozzle 125 can be directly facing the lower surface of the second disk 107; or, when there are 3 nozzles 125 and 3 disks 107, the first nozzle 125 can be directly facing the upper surface of the first disk 107, the second nozzle 125 can be directly facing the lower surface of the first disk 107 and the upper surface of the second disk 107, and the third nozzle 125 can be directly facing the lower ... The nozzle 125 can be directly facing the lower surface of the second disk 107 and the upper surface of the third disk 107; or, when there are 3 nozzles 125 and 3 disks 107, the first nozzle 125 can be directly facing the lower surface of the first disk 107 and the upper surface of the second disk 107, the second nozzle 125 can be directly facing the lower surface of the second disk 107 and the upper surface of the third disk 107, the third nozzle 125 can be directly facing the lower surface of the third disk 107, and so on. The positional relationship between the nozzles 125 and the disks 107 is used as an example in this embodiment of the invention, but it does not mean that the embodiment of the invention makes specific limitations on this.

[0094] It should also be noted that the number of nozzles 125 can be equal to, less than or more than the number of disks 107, and no specific restrictions are imposed here.

[0095] It should also be noted that when the self-destructing reagent is liquid, the nozzle 125 can be designed into a suitable shape according to the reagent composition and viscosity to achieve atomization effect, increase the adsorption capacity between the reagent and the disk, and enhance the damage effect on the disk.

[0096] In one embodiment, a high-speed axial flow fan or a high-speed gas nozzle, or other component that can spray the self-destructing reagent onto the disk, can be installed at the nozzle 125. This embodiment can spray the self-destructing reagent onto the disk to damage the disk and make the data stored on the disk unrecoverable, so as to prevent information leakage. This embodiment of the present invention does not impose specific limitations on this.

[0097] In addition, in some implementations, refer to Figure 1 and Figure 2 The detection unit 130 includes a sensing component, which can acquire the hard drive casing status information and send the casing status information to the first control unit 140. The first control unit 140 can receive the hard drive casing status information acquired by the sensing component and control the valve component to open according to the casing status information, so that the drive component 123 pushes the reagent bottle 122 to discharge the self-destructing reagent to the disk 107, thereby causing the disk 107 storing information in the mechanical hard drive to be automatically destroyed, and the data stored in the disk 107 cannot be recovered, in order to prevent information leakage.

[0098] In an alternative embodiment, such as Figure 6 As shown, the sensing component can be located on the upper cover 101 of the hard disk housing 100, or at other locations within the hard disk housing 100, or even inside the hard disk; no specific limitations are imposed here.

[0099] It should be noted that the sensing component can be either a non-contact or a contact sensing component; no specific restrictions are imposed here. For example, a non-contact sensing component can be a human body pyroelectric infrared sensor, vibration sensor, displacement sensor, or vision sensor, or other sensing components. A contact sensing component can be a pressure sensor or a temperature sensor, etc., and will not be listed in detail here.

[0100] For example, suppose the sensing component is a vision sensor, and the vision sensor is located inside the hard drive. When the hard drive casing is opened, the vision sensor captures an image of the person opening the casing and sends the image to the first control unit. The first control unit compares the image with a reference image stored in memory. When the comparison is inconsistent, the first control unit controls the valve component to open, so that the drive component pushes the reagent bottle to discharge the self-destructing reagent to the disk, thereby causing the disk storing information in the mechanical hard drive to be automatically destroyed. The data stored on the disk cannot be recovered to prevent information leakage. In this embodiment of the invention, the sensing component is a vision sensor as an example, but it does not mean that the embodiment of the invention is specifically limited in this respect.

[0101] For example, suppose the sensing component is a pressure sensor, and this pressure sensor is installed on the top cover of the hard drive casing. When the hard drive casing is opened abnormally (e.g., forcibly disassembled), the pressure sensor can sense the stress change in the casing. Then, the pressure sensor sends the casing status information to the first control unit. After receiving the casing status information from the pressure sensor, the first control unit controls the valve component to open according to the casing status information, so that the drive component pushes the reagent bottle to discharge the self-destructing reagent to the disk, thereby causing the disk storing information in the mechanical hard drive to be automatically destroyed. The data stored on the disk cannot be recovered, in order to prevent information leakage. In this embodiment of the invention, the sensing component is a pressure sensor as an example, but it does not mean that the embodiment of the invention is specifically limited in this respect.

[0102] Based on the hard disk structure described in the above embodiments, various embodiments of the hard disk self-destruction method are proposed below.

[0103] like Figure 7 As shown, Figure 7 This is a flowchart of a hard disk self-destruction method provided in an embodiment of the present invention. This hard disk self-destruction method can be applied to, for example... Figure 1 The hard disk in the illustrated embodiment may include, but is not limited to, steps S110 and S120.

[0104] Step S110: Receive status information from the detection unit;

[0105] Step S120: Control the valve component to open according to the status information, so that the drive component pushes the reagent bottle to discharge the self-destructing reagent to the disk.

[0106] In one embodiment, the self-destruct mechanism includes a valve component, a reagent bottle, and a drive component connected in sequence. The reagent bottle contains a self-destructing reagent, and the first control unit is connected to both the detection unit and the valve component. The first control unit can receive status information from the detection unit and control the valve component to open based on the status information. This causes the drive component to push the reagent bottle to discharge the self-destructing reagent to the disk, thereby automatically destroying the disk and rendering the data stored on it unrecoverable. Therefore, this embodiment of the invention can automatically activate the hard drive destruction function when a computer or hard drive is stolen or lost, so that the disk storing information on the hard drive is automatically destroyed and the data stored on it cannot be recovered, thus improving the security of hard drive data and preventing information leakage.

[0107] It should be noted that the self-destructing reagent can be sulfuric acid, hydrochloric acid, or a special destruction solution, or other reagents or ultrafine powders that can corrode or wear down the disk and make the data on the disk irrecoverable. No specific restrictions are imposed here.

[0108] It should be noted that there is no limit to the number of disks; it can be 1, 2, 4, or any other number. No specific restrictions are imposed here.

[0109] It should also be noted that the valve component can be installed on the side of the reagent bottle (such as the left side and near the bottle opening), or in other locations, without specific restrictions.

[0110] It should also be noted that the reagent bottle is connected to the valve component, and the self-destructing reagent in the reagent bottle can flow from the reagent bottle into the valve component.

[0111] It should be noted that a recess may be provided inside the hard drive, in which valve components, reagent bottles, and drive components are installed; alternatively, valve components, reagent bottles, and drive components may also be installed outside the hard drive, as long as the nozzle outlet is inside the hard drive, and no specific restrictions are imposed here.

[0112] It should be noted that the first control unit can be installed on the back of the hard drive casing, inside the hard drive casing, or in other locations; no specific restrictions are made here.

[0113] It should also be noted that the driving component may include a motor and a transmission assembly, or other driving components that can move the reagent bottle. The motor may be a servo motor or a stepper motor, etc., without specific limitations.

[0114] In another embodiment, when the hard disk further includes an external communication port connected to an external communication device and communicatively connected to the detection unit, then, referring to... Figure 8 Step S110 may include, but is not limited to, step S210.

[0115] Step S210: Receive the identification information of the external communication device through the detection unit.

[0116] In one embodiment, the hard drive can identify external communication devices connected to it. When the detection unit obtains the identification information of the external communication device, it sends the identification information to the first control unit. The first control unit receives the identification information from the detection unit and compares it with the authorized identification information in the hard drive (i.e., the identification information already stored on the disk). If the comparison is inconsistent, the first control unit controls the valve component to open, so that the drive component pushes the reagent bottle to discharge self-destructing reagent to the disk, thereby causing the disk storing information in the hard drive to be automatically destroyed, and the data stored on the disk cannot be recovered to prevent information leakage. Alternatively, if the comparison is consistent, the data exchange channel between the hard drive and the external communication device is opened, the hard drive works normally, and during the normal operation of the hard drive, the detection unit obtains the status information of the hard drive in real time to ensure the security of the data on the disk.

[0117] It should be noted that identification information may include MAC address, device serial number or user information, etc., and no specific restrictions are made here.

[0118] It should be noted that the external communication device can be a hard drive or other terminal devices, such as mobile phones, tablets, laptops, handheld computers, in-vehicle electronic devices, wearable devices, ultra-mobile personal computers (UMPCs), netbooks, or personal digital assistants (PDAs), etc. The embodiments of the present invention do not impose specific limitations.

[0119] In another embodiment, when the hard disk further includes an external self-destruct port, which is communicatively connected to the detection unit, and the first control unit and the second control unit are communicatively connected, then, referring to... Figure 9 The hard drive self-destruction method may include, but is not limited to, steps S310 and S320.

[0120] Step S310: Receive self-destruct control information from the external self-destruct port through the detection unit;

[0121] Step S320: Send self-destruct control information to the second control unit so that the second control unit controls the valve component to open according to the self-destruct control information so that the drive component pushes the reagent bottle to discharge the self-destruct reagent to the disk.

[0122] In one embodiment, the detection unit receives self-destruct control information from an external self-destruct port and sends the self-destruct control information to a first control unit. The first control unit then sends the received self-destruct control information to a second control unit. The second control unit analyzes the self-destruct control information. If the analysis result indicates that the hard drive or the computer containing the hard drive is in an abnormal state, the second control unit can control the valve component to open, causing the drive component to push the reagent bottle to discharge the self-destruct reagent to the disk, thereby automatically destroying the disk containing the information stored in the hard drive. The data stored on the disk cannot be recovered, improving the security of the hard drive data and preventing information leakage. If the analysis result indicates that the hard drive or the computer containing the hard drive is in a normal state, the hard drive operates normally. During the normal operation of the hard drive, the detection unit acquires the hard drive's status information in real time, such as the self-destruct control information, to ensure the security of the data on the disk.

[0123] It should be noted that the hard drive can communicate with the second control unit via an external self-destruct port. The second control unit is a control unit independent of the hard drive. For example, the second control unit can be located in another hard drive, or in other components, functional circuits, integrated circuits, or chips in the terminal device. The terminal device can be a mobile phone, tablet computer, laptop computer, PDA, in-vehicle electronic device, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc. The embodiments of the present invention do not impose specific limitations.

[0124] It should also be noted that the number of the second control unit is not limited; it can be one, two, four, or other numbers, and no specific restrictions are imposed here.

[0125] In another embodiment, when the hard disk further includes a power interface and a data interface, both of which are communicatively connected to the first control unit, then, referring to... Figure 10 The hard drive self-destruction method may include, but is not limited to, steps S410 and S420.

[0126] Step S410: Receive the first connection status information of the power interface and the second connection status information of the data interface through the detection unit;

[0127] Step S420: Control the data access permissions of the disk according to the first connection status information and the second connection status information respectively.

[0128] It should be noted that the first connection status information can be the connection status of the power cable connected to the power interface of the hard drive, and the second connection status information can be the connection status of the data cable connected to the data interface of the hard drive.

[0129] In an optional embodiment, when the first connection status information indicates that the power cable has been abnormally unplugged, the detection unit receives the first connection status information of the power interface and sends the first connection status information to the first control unit. The first control unit receives the first connection status information from the detection unit, records the first connection status information in the hard disk, and can control the data access permission of the disk to be inaccessible. When the first connection status information indicates that the power cable is connected normally, the first control unit can control the data access permission of the disk to be accessible. This embodiment of the invention does not impose specific limitations on this.

[0130] In an optional embodiment, when the second connection status information indicates that the data cable has been abnormally disconnected, the detection unit receives the second connection status information of the power interface and sends the second connection status information to the first control unit. The first control unit receives the second connection status information from the detection unit, records the second connection status information in the hard disk, and can control the data access permission of the hard disk to be inaccessible. When the second connection status information indicates that the data cable is connected normally, the first control unit can control the data access permission of the hard disk to be accessible. This embodiment of the invention does not impose specific limitations on this.

[0131] In one embodiment, when the hard drive is operating normally, the detection unit needs to perform real-time detection of the status of the external communication device connected to the external communication port, the external self-destruct port, the power interface, the data interface, and the hard drive casing to ensure that the data inside the hard drive is in a safe state. For example, such as... Figure 11 As shown, Figure 11This is a flowchart illustrating the normal operation of a hard drive. First, the hard drive's protection program is activated. The first step involves the detection unit checking the connection status of the power cable at the power interface and the data cable at the data interface, obtaining first connection status information for the power interface and second connection status information for the data interface. If the first connection status information indicates that the power cable has been improperly disconnected, this information is recorded on the hard drive; conversely, if the second connection status information indicates that the data cable has been improperly disconnected, this information is recorded on the hard drive. Next, the first control unit can control the disk's data access permissions to be inaccessible; otherwise, it can control the disk's data access permissions to be accessible. The detection unit and control unit then repeat the above process. The second step involves the detection unit identifying the external communication device. The detection unit obtains the identification information of the external communication device and sends it to the first control unit. The first control unit receives the identification information from the detection unit and compares it with the authorized identification information stored on the hard drive. The system compares the information (i.e., the identification information already stored on the disk) with the self-destruct information. If the comparison is inconsistent, a self-destruct program is initiated. The first control unit controls the valve component to open, so that the drive component pushes the reagent bottle to discharge the self-destruct reagent to the disk. If the comparison is consistent, the third step is executed, in which the detection unit detects the status of the external self-destruct port and obtains the self-destruct control information. The first control unit sends the self-destruct control information from the detection unit to the second control unit. The second control unit analyzes the self-destruct control information. If the analysis result indicates that the hard drive or the computer containing the hard drive is in an abnormal state, the self-destruct program is initiated. If the analysis result indicates that the hard drive or the computer containing the hard drive is in a normal state, the fourth step is executed, in which the detection unit obtains the hard drive's casing status information. If the casing status information indicates that the hard drive casing has been opened abnormally (e.g., forcibly disassembled), the self-destruct program is initiated. Otherwise, the channel for data exchange between the hard drive and the external communication device is opened, and the hard drive works normally. The above steps are continuously repeated until the hard drive is destroyed to ensure the security of the data on the disk. This embodiment of the invention does not impose specific limitations on this.

[0132] Additionally, refer to Figure 12 As shown, one embodiment of the present invention also provides a hard disk 200, which includes a memory 202, a processor 201, and a computer program stored on the memory 202 and executable on the processor 201.
