Fig. 1 is a schematic diagram of a hardware structure of a terminal device applied in the embodiment of the present application. As shown in fig. 1, the terminal device 100 includes a display device 110, a processor 120, and a memory 130. The memory 130 may be used to store software programs and data, and the processor 120 executes various functional applications and data processing of the terminal device 100 by operating the software programs and data stored in the memory 130. The memory 130 may mainly include a program storage area and a data storage area, wherein the program storage area may store an operating system, an application program (such as an image capturing function) required by at least one function, and the like; the storage data area may store data (such as audio data, a phonebook, etc.) created according to the use of the terminal device 100, and the like. Further, the memory 130 may include high speed random access memory, and may also include non-volatile memory, such as at least one magnetic disk storage device, flash memory device, or other volatile solid state storage device, among others. The processor 120 is a control center of the terminal device 100, connects various parts of the entire terminal device by various interfaces and lines, and performs various functions of the terminal device 100 and processes data by running or executing software programs and/or data stored in the memory 130, thereby performing overall monitoring of the terminal device. The Processor 120 may include one or more general-purpose processors, and may further include one or more Digital Signal Processors (DSPs) for performing related operations to implement the technical solutions provided in the embodiments of the present application.

The terminal device 100 may further include an input device 140 for receiving input numerical information, character information, or contact touch operation/non-contact gesture, and generating signal input related to user setting and function control of the terminal device 100, and the like. Specifically, in the embodiment of the present application, the input device 140 may include a touch panel 141. The touch panel 141, also referred to as a touch screen, may collect touch operations of a user (e.g., operations of the user on the touch panel 141 or on the touch panel 141 using any suitable object or accessory such as a finger or a stylus) thereon or nearby, and drive the corresponding connection device according to a preset program. Alternatively, the touch panel 141 may include two parts of a touch detection device and a touch controller. The touch detection device detects the touch direction of a user, detects a signal brought by touch operation and transmits the signal to the touch controller; the touch controller receives touch information from the touch sensing device, converts the touch information into touch point coordinates, sends the touch point coordinates to the processor 120, and can receive and execute commands sent by the processor 120. For example, when the user clicks an icon or legend corresponding to an application with a finger on the touch panel 141, the touch detection device detects the signal caused by the click and transmits the signal to the touch controller, the touch controller converts the signal into coordinates and transmits the coordinates to the processor 120, and the processor 120 determines the operation (open) to be performed on the icon or legend according to the coordinates and the type of the signal (single click or double click).
The touch panel 141 can be implemented by various types, such as resistive, capacitive, infrared, and surface acoustic wave. In addition to the touch panel 141, the input device 140 may include other input devices 142, and the other input devices 142 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, a joystick, and the like.
The display device 110 includes a display panel 111 for displaying information input by a user or information provided to the user, various menu interfaces of the terminal device 100, and the like, and in the embodiment of the present application, is mainly used for displaying a picture captured by a camera in the terminal device 100. Alternatively, the Display panel 111 may be configured by a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED). In some other embodiments, the touch panel 141 can cover the display panel 111 to form a touch display screen.
In addition to the above, the terminal device 100 may further include a power supply 150 for supplying power to other modules. The terminal device 100 may also include one or more sensors 170, such as an acceleration sensor, a light sensor, a GPS sensor, an infrared sensor, a laser sensor, a position sensor, or a lens pointing angle sensor, among others.

The following is a method for removing a removable data storage device according to a specification operation for a user, which is referred to in the embodiments of the present application. Taking the removable data storage device as an SD card as an example:
if the SD card is removed according to the standard operation of the SD card, the data damage problem can not occur, and the standard action is as follows: before the user pulls out the SD card, the SD card is unloaded in the device, and after the unloading is successful (at the moment, the system of the terminal equipment does not have any SD card reading and writing operation any more), the SD card can be taken out safely.
If the removable data storage device is not removed as per the above specification, data corruption, or even removable data storage device corruption, may result. The embodiment of the application provides a data processing method and device, which can avoid the problem of data damage caused by the fact that a movable data storage device is not removed according to the operation of the specification to a certain extent. The method and the device are based on the same inventive concept, and because the principles of solving the problems of the method and the device are similar, the implementation of the device and the method can be mutually referred, and repeated parts are not repeated.
