Fig. 1 is a flowchart of a method for writing a hard disk file according to an embodiment of the invention.

A hard disk file writing method comprises the following steps of:

s100: and obtaining read-write operation.

In this embodiment, the hard disk needs to perform reading and writing of the file to update data in the hard disk, and each reading and writing operation includes two operations of reading and writing the file of the hard disk, where the two operations are both to update the data in the hard disk, and the updated data includes the data in the key area and the data in the data area, so that the reading and writing operation needs to be acquired and analyzed, so that the file corresponding to the reading and writing operation is convenient to acquire, further, the comparison between the file and the preset file is convenient, and the subsequent judgment of whether the reading and writing operation is the modification of the data in the key area of the hard disk is also convenient.

S200: and detecting whether the file corresponding to the read-write operation is a preset file or not.

In this embodiment, each read-write operation has a corresponding read-write file, and each read-write operation has a corresponding file including corresponding update data. The file corresponding to each read-write operation is converted through the application program FAT32 file system, namely, the data in each read-write operation is converted into the corresponding read-write file, the type and the file name of the read-write file are determined according to the data content of the read-write operation, and according to the comparison result of the file corresponding to the read-write operation and the preset file, whether the data corresponding to the current read-write operation is used for updating the key area or not is conveniently judged, so that the subsequent protection of the data of the key area is facilitated. In this embodiment, the preset file is a file of a preset type, or a file of a preset name, or a file of a name with a preset rule.

S300: when the file corresponding to the read-write operation is a preset file, writing the data corresponding to the read-write operation into a data area according to the read-write operation, and not updating the data of a key area, wherein the data area is used for storing the data file, and the key area is used for storing the guide file.

In this embodiment, according to the comparison result of the file corresponding to the read-write operation and the preset file, it is determined whether the data corresponding to the read-write operation includes data for the key area, for example, when the file corresponding to the read-write operation is the preset file, the file corresponding to the read-write operation at this time is matched with the preset file, that is, the file corresponding to the read-write operation is the same as or similar to the preset file, that is, the file corresponding to the read-write operation is one of the preset files, so that the data corresponding to the read-write operation includes data for updating the key area and data for the data area, and the data for the key area is used for indicating the position and specific data content of the data area, that is, the data for the key area is a file with an index function, that is, the guide file stored in the key area points to the corresponding data area, that is worth mentioning, the key area may also be referred to as the key information area, or referred to as the index area, and the key area is used for storing the index information, that is, the file. In order to avoid the situation that the critical area is damaged when the data of the critical area is updated during hard disk faults, the data of the critical area is not updated at the moment, the data integrity of the critical area is ensured, the situation that the data of the critical area is interrupted in the updating process is avoided, the fact that the critical area still points to the corresponding data area is ensured, and further the data loss of the data area is avoided.

In an embodiment, the step of detecting whether the file corresponding to the read-write operation is a preset file further includes: and when the file corresponding to the read-write operation is not a preset file, writing the data corresponding to the read-write operation into the data area according to the read-write operation, and updating the data of the key area. And the file corresponding to the read-write operation is not matched with the preset file, namely the file corresponding to the read-write operation does not belong to the preset file. The preset file includes a plurality of files, for example, the preset file includes at least one of a video file, an audio file, an image file, an index file, a disk information file, a video query record file, and a log file. The file corresponding to the read-write operation is not the preset file, that is, the file corresponding to the read-write operation does not belong to any one of a video file, an audio file, an image file, an index file, a disk information file, a video query record file and a log file, but the video file, the audio file, the image file, the index file, the disk information file, the video query record file and the log file are important files of the hard disk, wherein the important files comprise data updated to the key area. Therefore, the data corresponding to the read-write operation does not include the data corresponding to the preset file, so that the update of the key area and the data area by the data corresponding to the read-write operation is not influenced, namely, the data corresponding to the read-write operation does not influence the key area corresponding to the preset file when the data corresponding to the read-write operation is updated. In addition, it should be noted that, because the capacity and the number of the critical areas are fixed in the process of initializing the partition of the hard disk, when the data corresponding to the read-write operation needs to be written into the critical areas, the data of the original critical areas can only be replaced, that is, the data corresponding to the read-write operation is replaced by the current data of the critical areas, that is, the original data of the critical areas is covered by the data corresponding to the read-write operation.

In this embodiment, the key areas include a first key area for storing the directed file and a second key area for storing the data file. In this embodiment, when the file corresponding to the read-write operation is a preset file, writing the data corresponding to the read-write operation into the data area according to the read-write operation, and not updating the data of the first key area, that is, not updating the guide file of the first key area; and when the file corresponding to the read-write operation is not a preset file, writing the data corresponding to the read-write operation into the data area according to the read-write operation, and updating the data of the second key area, namely updating the data of the second key area.

When the file corresponding to the reading operation is matched with the preset file, the data of the first key area will not be updated, so that the data of the first key area is prevented from being interrupted in the updating process, namely, the data of the first key area is prevented from being damaged, and the situation that the data of the data area corresponding to the first key area is lost is avoided. The data of the first key area is irrelevant to the data of the preset file, namely, the data of the first key area is irrelevant to the data of the preset file, and when the file corresponding to the read-write operation is not the preset file, the data of the second key area is relevant to the data of the file corresponding to the read-write operation at the moment, the data of the second key area is updated at the moment and does not influence the first key area, namely, the data of the first key area is not modified by modifying the data of the second key area at the moment. And when the file corresponding to the read-write operation is not the preset file, the file corresponding to the read-write operation is not an important file of the hard disk, and at the moment, the update of the file corresponding to the read-write operation on the hard disk does not affect the data of the first key area, so that when the file corresponding to the read-write operation is not the preset file, the data corresponding to the read-write operation only updates the data of the second key area, and the data of the first key area and the data area corresponding to the first key area are not updated, thereby keeping the data of the first key area intact and avoiding the loss of important file information of the hard disk.

In an embodiment, the first critical section includes first critical data and second critical data, the second critical data is a backup of the first critical data, that is, when the first critical data is damaged, the second critical data is used as data of the first critical section, that is, when the first critical data is damaged, the second critical data replaces the first critical data, for example, the first critical data includes data of a FAT1 table, and the second critical data includes data of a FAT2 table.

In an embodiment, when the file corresponding to the read-write operation is not a preset file, writing the data corresponding to the read-write operation into the data area according to the read-write operation, and updating the data of the key area includes: and when the file corresponding to the read-write operation is not a preset file, writing the data corresponding to the read-write operation into the data area according to the read-write operation, updating the data of the second key area, and not updating the data of the first key area. Because the file corresponding to the read-write operation is not matched with the preset file, that is, the file corresponding to the read-write operation is not an important file required by the hard disk, that is, the file corresponding to the read-write operation does not belong to any one of a video file, an image file, an index file, a disk information file, a video query record file and a log file, that is, the operations of reading and writing the file corresponding to the read-write operation do not affect the content of the important file in the hard disk, and the data of the file corresponding to the read-write operation at the moment does not update the data of the first key area. The file corresponding to the read-write operation at the moment can be written into the hard disk, so that the file corresponding to the read-write operation at the moment is updated by updating the data of the second key area and the corresponding data area, and the data of the first key area is not updated, namely, the data of the second key area is updated by the file corresponding to the read-write operation at the moment and the data of the first key area are not updated through the control of a system program, so that even if the hard disk is in fault or the system is suddenly powered off or is damaged by people, the data of the first key area is not updated due to the fact that the data of the second key area is only updated, so that the first key area is not affected, namely, the data of the first key area is not updated, and the guide file of the first key area is not damaged, and the data loss of the data area corresponding to the first key area is avoided.

In this embodiment, the first key area is used to store a first file, the second key area is used to store a second file, the first file is used to guide the first data file in the data area, the second file is used to store the second data file in the data area, and the data update of the data area includes updating the attribute of the file in the data area and updating specific data in the file.

In an embodiment, the step of detecting whether the file corresponding to the read-write operation is a preset file includes: and detecting whether the file name of the file corresponding to the read-write operation is a preset file name. The file names of the preset files have different formats, and only when the format of the file name of the file corresponding to the read-write operation is the same as that of the file name of the preset file, the system program judges that the file corresponding to the current read-write operation belongs to the preset file, for example, the preset file comprises a video file and an image file, and the corresponding file name belongs to the range between 00000000 and 0 FFFFF; for another example, the preset file includes an index file, and a corresponding file name is RECINDEX; for another example, the preset file includes a disk information file, and the corresponding file name is DISKINFO; for another example, the preset file includes a video query record file, and the corresponding file name is DVRREC01; for another example, the preset file includes a log file, and the corresponding file name is dvr_lobb. In the process of each read-write operation, the file corresponding to the read-write operation generates a corresponding file name through the application FAT32 file system, and the file name of the file corresponding to the read-write operation is converted according to the data contained in the file, for example, if the file corresponding to the read-write operation contains video data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the video file through the application FAT32 file system; for another example, if the file corresponding to the read-write operation includes photo data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the image file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes index data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the index file through the application FAT32 file system; for another example, if the file corresponding to the read-write operation includes disk information data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the disk information file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes the record query record data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the record query record file through the application program FAT32 file system; for another example, if the file corresponding to the read/write operation includes log data, the file name of the file corresponding to the read/write operation is converted into the file name corresponding to the log file through the application FAT32 file system.

Moreover, according to the comparison result of the file name of the file corresponding to the read-write operation and the file name of the preset file, the system program executes corresponding steps, for example, when the file name of the file corresponding to the read-write operation is the file name of the preset file, the data corresponding to the read-write operation is written into the data area according to the read-write operation, and the data of the key area is not updated; for another example, when the file name of the file corresponding to the read-write operation is not the file name of the preset file, writing the data corresponding to the read-write operation into the data area according to the read-write operation, and updating the data of the key area. Therefore, when the hard disk executes the read-write operation, the comparison of the files can be realized according to the file names, so that the comparison between the files corresponding to the read-write operation and the preset files is more convenient, and the file reading and writing efficiency is improved.

In an embodiment, the step of detecting whether the file corresponding to the read-write operation is a preset file includes: and detecting whether the file type of the file corresponding to the read-write operation is a preset file type. The file types of the preset files have different formats, and in this embodiment, the file types are file suffix names. Only when the format of the file type corresponding to the read-write operation is the same as the format of the file type of the preset file, the system program judges that the file corresponding to the current read-write operation belongs to the preset file, for example, the preset file comprises a video file, and the corresponding file type is bsv; for another example, the preset file includes an image file, and the corresponding file type is bsp; for another example, the preset file includes one of an index file, a disk information file, a video query record file and a log file, and the corresponding file type is dat. In the process of each read-write operation, the file corresponding to the read-write operation generates a corresponding file type through the application FAT32 file system, and the file type of the file corresponding to the read-write operation is converted according to the data contained in the file, for example, if the file corresponding to the read-write operation contains video data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the video file through the application FAT32 file system; for another example, if the file corresponding to the read-write operation includes photo data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the image file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes index data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the index file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes disk information data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the disk information file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes the video query record data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the video query record file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes log data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the log file through the application FAT32 file system.

Moreover, according to the comparison result of the file type of the file corresponding to the read-write operation and the file type of the preset file, the system program executes corresponding steps, for example, when the file type of the file corresponding to the read-write operation is the file type of the preset file, the data corresponding to the read-write operation is written into the data area according to the read-write operation, and the data of the key area is not updated; for another example, when the file type of the file corresponding to the read-write operation is not the file type of the preset file, writing the data corresponding to the read-write operation into the data area according to the read-write operation, and updating the data of the key area. Therefore, when the hard disk executes the read-write operation, the comparison of the files can be realized according to the file types, so that the comparison between the files corresponding to the read-write operation and the preset files is more convenient, and the file reading and writing efficiency is improved.

In an embodiment, the step of detecting whether the file corresponding to the read-write operation is a preset file includes: and detecting whether the file name and the file type of the file corresponding to the read-write operation are the file name and the file type of a preset file. And comparing the file name of the file with two parameters of the file type, so as to judge whether the file corresponding to the read-write operation is a preset file or not. That is, the comparison of the file corresponding to the read-write operation and the preset file is to perform the comparison of the file name and the file type respectively, and only if the two parameters are matched, the system program can judge that the file corresponding to the read-write operation is the preset file, so that the matching similarity between the file corresponding to the read-write operation and the preset file is higher through the comparison of the file name and the file type, the comparison accuracy of the file corresponding to the read-write operation is improved, and the reliability of the file stored in the hard disk is higher.

In an embodiment, the step of detecting whether the file corresponding to the read-write operation is a preset file further includes: and when the file corresponding to the read-write operation is a preset file and the read-write operation does not have the data written in the data area, the data of the key area is not updated. In this embodiment, the file corresponding to the read-write operation at this time only includes the data of the critical area, and the file corresponding to the read-write operation at this time is a preset file, so that the data included in the file corresponding to the read-write operation at this time is the data of the first critical area, that is, the file corresponding to the read-write operation at this time is the guide file of the first critical area. In this way, the system program correspondingly executes the data of the first key area, namely the data of the first key area is not updated, namely the guide file of the first key area is not updated, so that the data of the first key area is not destroyed, and the data loss of the data area corresponding to the first key area is avoided.

In an embodiment, the method further includes the following steps before the read-write operation is acquired: creating a hard disk partition; distributing the sizes and the numbers of various information files according to the capacity sizes of the partitions; a plurality of different purpose preset files are created. The hard disk partition is to divide the capacity of the hard disk, for example, divide the hard disk into equal volumes, and the capacity in each partition is equal, so that the number of files stored in each partition is equal. Furthermore, functional area division is required to be performed on each partition after the hard disk partition, so that each partition has a corresponding key area and a data area; the data in each partition is distributed, namely, different data in each partition are distributed into the corresponding files, so that the management of the data is facilitated; and then, distributing the files corresponding to the data with the same function to the pre-distributed files according to different functions of the data in the files, wherein the pre-distributed files with higher importance are used as the follow-up preset files, wherein the importance of the pre-distributed files is determined according to the file names and the file types, and the files with specific file names and the file types, which are designated by a system program, can be also used, for example, the preset files are files containing the data of the key areas.

The following is one specific example:

in this embodiment, the preset files include video files, audio files, and image files, for example, the names of the video files are from 01000000.Bsv to 0100000. Bsv, when the file name detected by the corresponding file of the read-write operation is 01010000.Bsv, the corresponding file name is within the range of the video file name, that is, the corresponding file of the current read-write operation belongs to the preset file, that is, the corresponding data of the video file in the hard disk is updated by the current read-write operation, wherein the updating of the corresponding video data in the data area includes the modification of the information of the file size, the file access, the modification time and the like of the key area, and in order to avoid the interruption of the data in the key area caused by the hard disk fault during the updating, the system program controls the hard disk to not update the data in the key area at this time, so that the data in the key area is not destroyed, the data in the data area can still be updated, the guide file damage of the key area is avoided, and the old data in the key area can still be used for the updating the data area, and the loss of the data in the corresponding data area can be avoided. As for the audio file, the image file and other files belonging to the preset file, the method steps are the same as the above steps, and will not be repeated here.

In one embodiment, referring to fig. 2, a hard disk file writing device 10 is provided, which includes: an obtaining module 110, configured to obtain a read-write operation; the detection module 120 is configured to detect whether the file corresponding to the read-write operation is a preset file; and the analysis processing module 130 is configured to write data corresponding to the read-write operation into a data area according to the read-write operation when the file corresponding to the read-write operation is a preset file, and not update data of a key area, where the data area is used for storing data files, and the key area is used for storing index files.

In an embodiment, when the detection module detects that the file corresponding to the read-write operation is not a preset file, the analysis processing module writes the data corresponding to the read-write operation into the data area according to the read-write operation, and updates the data of the key area. The detection module transmits the information that the file corresponding to the read-write operation is not the preset file to the analysis processing module, and the analysis processing module correspondingly executes the processing instruction after acquiring the information, for example, the analysis processing module controls the writing of the data corresponding to the read-write operation into the data area and controls the data updating of the key area. The preset file includes a plurality of files, for example, the preset file includes at least one of a video file, an image file, an index file, a disk information file, a video query record file, and a log file. The file corresponding to the read-write operation is not the preset file, that is, the file corresponding to the read-write operation does not belong to any one of a video file, an image file, an index file, a disk information file, a video query record file and a log file, and the video file, the image file, the index file, the disk information file, the video query record file and the log file are important files of the hard disk, wherein the important files comprise data updated to the key area. Therefore, the data corresponding to the read-write operation does not include the data corresponding to the preset file, so that the update of the key area and the data area by the data corresponding to the read-write operation is not influenced, namely, the data corresponding to the read-write operation does not influence the key area corresponding to the preset file when the data corresponding to the read-write operation is updated. In addition, it should be noted that, because the capacity and the number of the critical areas are fixed in the process of initializing the partition of the hard disk, when the data corresponding to the read-write operation needs to be written into the critical areas, the data of the original critical areas can only be replaced, that is, the data corresponding to the read-write operation is replaced by the current data of the critical areas, that is, the original data of the critical areas is covered by the data corresponding to the read-write operation.

In an embodiment, the analysis processing module is configured to write the data corresponding to the read-write operation into the data area according to the read-write operation when the file corresponding to the read-write operation is not a preset file, and update the data of the second critical area, and not update the data of the first critical area. The key areas comprise a first key area and a second key area, the first key area is used for storing guide files corresponding to the preset files, and the second key area is used for storing data files except the preset files. When the file corresponding to the reading operation is matched with the preset file, the data of the first key area will not be updated, so that the data of the first key area is prevented from being interrupted in the updating process, namely, the data of the first key area is prevented from being damaged, and the situation that the data of the data area corresponding to the first key area is lost is avoided. The data of the first key area is irrelevant to the data of the preset file, namely, the data of the first key area is irrelevant to the data of the preset file, and when the file corresponding to the read-write operation is not the preset file, the data of the second key area is relevant to the data of the file corresponding to the read-write operation at the moment, the data of the second key area is updated at the moment and does not influence the first key area, namely, the data of the first key area is not modified by modifying the data of the second key area at the moment. And when the file corresponding to the read-write operation is not the preset file, the file corresponding to the read-write operation is not an important file of the hard disk, and at the moment, the update of the file corresponding to the read-write operation on the hard disk does not affect the data of the first key area, so that when the file corresponding to the read-write operation is not the preset file, the data corresponding to the read-write operation only update the data of the second key area and the corresponding data area, and the data of the first key area and the corresponding data area are not updated, thereby keeping the data of the first key area intact and avoiding the loss of important file information of the hard disk. Because the file corresponding to the read-write operation is not matched with the preset file, that is, the file corresponding to the read-write operation is not an important file required by the hard disk, that is, the file corresponding to the read-write operation does not belong to any one of a video file, an image file, an index file, a disk information file, a video query record file and a log file, that is, the operations of reading and writing the file corresponding to the read-write operation do not affect the content of the important file in the hard disk, and the data of the file corresponding to the read-write operation at the moment does not update the data of the first key area. The file corresponding to the read-write operation at the moment can be written into the hard disk, so that the file corresponding to the read-write operation at the moment is updated by updating the data of the second key area, and the data of the first key area is not updated, namely, the data of the second key area is not updated by the file corresponding to the read-write operation at the moment under the control of a system program, and the data of the first key area is not updated, so that even if the hard disk is in fault or the system is suddenly powered off or is damaged artificially, the data of the first key area is not updated due to the fact that the data of the second key area is only updated, namely, the data of the first key area is not updated, the guide file of the first key area is not damaged, and the data loss of the data area corresponding to the first key area is avoided.

In an embodiment, the detection module is configured to detect whether a file name of a file corresponding to the read-write operation is a preset file name. The file names of the preset files have different formats, and only when the format of the file name of the file corresponding to the read-write operation is the same as that of the file name of the preset file, the system program judges that the file corresponding to the current read-write operation belongs to the preset file, for example, the preset file comprises a video file and an image file, and the corresponding file name belongs to the range between 00000000 and 0 FFFFF; for another example, the preset file includes an index file, and a corresponding file name is RECINDEX; for another example, the preset file includes a disk information file, and the corresponding file name is DISKINFO; for another example, the preset file includes a video query record file, and the corresponding file name is DVRREC01; for another example, the preset file includes a log file, and the corresponding file name is dvr_lobb. In the process of each read-write operation, the file corresponding to the read-write operation generates a corresponding file name through the application FAT32 file system, and the file name of the file corresponding to the read-write operation is converted according to the data contained in the file, for example, if the file corresponding to the read-write operation contains video data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the video file through the application FAT32 file system; for another example, if the file corresponding to the read-write operation includes photo data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the image file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes index data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the index file through the application FAT32 file system; for another example, if the file corresponding to the read-write operation includes disk information data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the disk information file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes the record query record data, the file name of the file corresponding to the read-write operation is converted into the file name corresponding to the record query record file through the application program FAT32 file system; for another example, if the file corresponding to the read/write operation includes log data, the file name of the file corresponding to the read/write operation is converted into the file name corresponding to the log file through the application FAT32 file system.

In an embodiment, the detection module is configured to detect whether a file type of the file corresponding to the read-write operation is a preset file type. The file types of the preset files have different formats, and in this embodiment, the file types are file suffix names. Only when the format of the file type corresponding to the read-write operation is the same as the format of the file type of the preset file, the system program judges that the file corresponding to the current read-write operation belongs to the preset file, for example, the preset file comprises a video file, and the corresponding file type is bsv; for another example, the preset file includes an image file, and the corresponding file type is bsp; for another example, the preset file includes one of an index file, a disk information file, a video query record file and a log file, and the corresponding file type is dat. In the process of each read-write operation, the file corresponding to the read-write operation generates a corresponding file type through the application FAT32 file system, and the file type of the file corresponding to the read-write operation is converted according to the data contained in the file, for example, if the file corresponding to the read-write operation contains video data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the video file through the application FAT32 file system; for another example, if the file corresponding to the read-write operation includes photo data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the image file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes index data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the index file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes disk information data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the disk information file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes the video query record data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the video query record file through the application program FAT32 file system; for another example, if the file corresponding to the read-write operation includes log data, the file type of the file corresponding to the read-write operation is converted into the file type corresponding to the log file through the application FAT32 file system.

In an embodiment, the analysis processing module is configured to not update the data of the key area when the file corresponding to the read-write operation is a preset file and the read-write operation does not have the data written into the data area. The file corresponding to the read-write operation only contains the data of the key area, and the file corresponding to the read-write operation is a preset file, so that the data contained in the file corresponding to the read-write operation at the moment is the data of the first key area, namely the file corresponding to the read-write operation at the moment is the guide file of the first key area. In this way, the system program correspondingly executes the data of the first key area, namely the data of the first key area is not updated, namely the guide file of the first key area is not updated, so that the data of the first key area is not destroyed, and the data loss of the data area corresponding to the first key area is avoided.
