Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

Referring to fig. 1, fig. 1 is a diagram illustrating a method for implementing a dual file system according to an embodiment of the present application, including:

s110, dividing the storage device of the target device into a plurality of storage partitions, wherein the target device is an electronic device using a private file system, and the private file system is a hard disk file operating system used by the target device for managing the storage partitions.

The storage device of the target device may be a hard disk, an SD Card (Secure Digital Memory Card), or the like. The private file system may be a hard disk file operating system used by each of different manufacturers, and specific contents of the private file system may refer to the prior art and are not described herein again.

The storage device may also be configured to store data of the target device during operation, including a work log, a cache, an execution result, and the like, for example, when the target device is a video monitoring device, the storage device may store data of a monitoring video, and when the target device is a recording device, the storage device may store recorded audio data. In some other embodiments, the target device may also be another device with a private file system, which is not listed here for brevity.

In this embodiment, the storage device of the target device may be accessed to other electronic devices, for example, the storage device may be an SD card, a usb disk, a hard disk, and the like, and may be used to access other electronic devices except the target device; the target device may also be an electronic device that provides an interface for opening its own storage device to the outside, so that other electronic devices can read and write the storage device of the target device. The standard file system can be a hard disk file operating system such as fat32/Ext4, and other electronic equipment can be a computer, a mobile phone and the like. The specific content of the standard file system may refer to the prior art, which is not described herein again.

In this embodiment, the storage device of the storage device may be divided to obtain a plurality of storage partitions, so that different storage partitions are used to store the private file system data and the standard file system data, respectively. Wherein the standard file system is a hard disk file operating system used by other electronic devices except the target device to manage the storage partition.

When the storage device is partitioned, an existing partitioning tool or system, for example, an MBR (Master Boot Record) partitioning management system, a GPT (global unique identification Table) partitioning management system, or a partitioning tool provided by the electronic device itself, may be used, and a specific implementation process of partitioning may refer to the prior art and is not described in detail.

S120, configuring a first partition and a second partition in a plurality of storage partitions; the first partition and the second partition are respectively an inactive partition and an active partition.

After the other electronic device accesses the storage device of the target device, the other electronic device detects data in the storage device of the target device, so as to determine a hard disk file operating system used by the storage device of the target device, and the other electronic device can mount the first identified hard disk file operating system. When the private file system is detected and identified, other electronic devices may not be able to identify the private file system, and then perform a formatting operation on the storage device of the target device, thereby causing the data of the private file system to be damaged.

To avoid the above situation, in this embodiment, two memory partitions of the divided memory partitions may be configured to obtain a first partition which is an inactive partition and a second partition which is an active partition.

In this embodiment, the inactive partition is a storage partition that is not detected and identified by other electronic devices, and the active partition is a storage partition that can be normally detected and identified by other electronic devices. Therefore, after the storage device of the target device is accessed to other electronic devices, the other electronic devices do not detect and identify the inactive partition, but normally detect and identify the active partition.

In this embodiment, the two selected memory partitions may be any two memory partitions whose available memory sizes meet the requirement. The data of the private file system and the data of the standard file system have certain sizes, and the storage partitions with the sizes corresponding to the private file system and the standard file system or larger than the private file system and the standard file system can be selected for configuration. The data sizes of the private file system and the standard file system may be different according to different hard disk file operating systems used by different manufacturers, and the data sizes of the private file system and the standard file system are not limited herein.

In one embodiment, partition attributes of different storage partitions are modified respectively based on a preset partition rule to obtain a first partition and a second partition; the preset partition rule comprises definitions of partition attributes of the inactive partition and the active partition respectively, and the partition attributes represent types of the storage partitions.

In this embodiment, each storage partition has respective partition attributes, including partition size, number of sectors, partition type, and the like. The preset partition rule includes definitions of partition attributes of the inactive partition and the active partition, respectively, so that after the memory partition is configured according to the preset partition rule, a first partition with the inactive partition attributes and a second partition with the active partition attributes can be obtained.

In this embodiment, the partition type may be modified to configure the storage partition into the first partition and the second partition. In some other embodiments, the first partition and the second partition may be further marked by adding a flag for characterizing the inactive partition and the active partition, so that the other electronic device preferentially detects the flag and determines the type of the partition by the flag. It is understood that there are various ways to actually configure the memory partition, and the details are not described herein.

S130, storing the private file system data and the standard file system data based on the first partition and the second partition respectively.

In combination with the above, the standard file system is a hard disk file operating system used by other electronic devices, and the other electronic devices are electronic devices such as mobile phones and computers which can be connected with external storage devices.

In this embodiment, after the first partition and the second partition are obtained, the private file system data and the standard file system data may be stored in the first partition and the second partition, respectively. The working data of the target device may be stored in the second partition, or may be stored in other partitions besides the first partition and the second partition.

In some other embodiments, the first partition and the second partition may also be used to store other data. For example, some more important data may be stored in the first partition, such as privacy data, data of an operating program of the target device, and the like, so as to avoid other storage devices from reading and writing the data. The data type in the form can be put into the first partition by setting a judgment threshold of the importance degree and calculating the importance degree of the data to judge whether the data needs to be stored into the first partition or presetting the form of the data type.

Some data that can be obtained by the outside world or data that needs to be provided to the outside world can be stored in the second partition. For example, the target device may include data that needs to be debugged, and when the target device is a monitoring device, the target device may further include monitoring data that can be provided to the outside. The part of data can be read and written by the outside by storing into the second partition.

It can be understood that the data stored in the first partition and the second partition can be reasonably set according to the user requirements, and are not described herein any more.

Through the method, when the storage device of the target device is accessed to other electronic devices, if the other electronic devices detect and recognize that the first partition is the inactive partition, the data in the storage partition is not further recognized, and the other storage partitions are detected instead, so that the private file system data in the first partition are protected. And if the other electronic equipment detects and identifies the second partition as the active partition, identifying the second partition, acquiring data of the standard file system in the second partition, and realizing read-write operation on the storage equipment of the target equipment based on the standard file system.

In the embodiment of the application, the storage device is split, so that different storage partitions can be obtained, and different functions can be realized through different storage partitions. Thus, the storage partition may be configured to configure the first partition and the second partition as an inactive partition and an active partition, respectively, the inactive partition storing data of the private file system and the active partition storing data of the standard file system, thereby enabling the target device to use the private file system and the standard file system at the same time. When the storage device of the target device is accessed into other electronic devices, if the partition is identified to be an inactive partition, the identification is not continued, so that the data of the private file system is protected from being read and damaged, then other electronic devices can identify other partitions, and when the partition is identified to be an active partition, the other electronic devices can realize normal reading and writing of the storage device of the target device through the data of the standard file system in the active partition. Therefore, after the storage device of the target device is accessed to other electronic devices, the other electronic devices can perform read-write operation on the storage device of the target device through the standard file system, and the private file system is not damaged, so that the data of the private file system is protected.

Currently, many MBR partition management systems are available for partition management. After the storage device is divided, a plurality of partitions are obtained, each partition comprises a plurality of sectors, one sector is 512 bytes, and the sectors are used for representing the space capacity of the storage device. However, if the MBR partition management system uses four bytes to store the total number of sectors in one storage partition, the maximum total number of sectors in one storage partition can be expressed as a power of 32 of 2, and therefore, when the MBR partition management system is used for partitioning, the maximum space capacity that the MBR partition management system can partition cannot exceed 2TB, that is, the maximum available space size of the MBR partition management system is 2TB. The specific principle of the MBR partition management system can refer to the prior art, and is not expanded in detail here.

However, the respective storage devices of different electronic devices may have different sizes of space capacities, for example, the space capacities of the different storage devices are 32G, 512G, 6TB, 8TB, and so on, respectively. When the space capacity is large, partitions obtained by partitioning based on the MBR partition management system cannot fully utilize the space capacity of the storage device, and the GPT partition management system can partition the storage device with any size of space capacity and can fully utilize the space capacity of the storage device.

In order to solve the above problem, in the embodiment provided in the application, when the storage device is divided into a plurality of storage partitions, a target partition management system corresponding to the space capacity of the storage device may be further determined based on the space capacity of the storage device and a preset relationship between the space capacity and the partition management system; the storage device is partitioned into a plurality of storage partitions using a target partition management system.

In this embodiment, the preset relationship includes a space capacity and a corresponding partition management system. Therefore, the partition management system corresponding to the space capacity of the storage device of the target device can be selected for partitioning, and waste of the space capacity of the storage device is avoided.

In one embodiment, the preset relationship includes a relationship between a preset space threshold, a space capacity size, and a corresponding partition management system.

In this embodiment, the size of the preset spatial threshold is 2TB.

In this embodiment, determining the target partition management system corresponding to the space capacity of the storage device may include:

when the space capacity of the storage device of the target device is determined to be greater than the preset space threshold, the GPT partition management system may be used for partitioning, that is, the GPT partition management system is determined to be the target partition management system.

When the space capacity of the storage device of the target device is determined to be less than or equal to the preset space threshold, the MBR partition management system may be used for partitioning, that is, the MBR partition management system is determined to be the target partition management system.

In the embodiment of the present application, because the partition management systems used are different, the manners of configuring the first partition and the second partition are also different, and then, after the partition is performed by using the MBR partition management system and the GPT partition management system, the configuration process of the first partition and the second partition will be described.

For the MBR partition management system, the MBR partition table data of different storage partitions can be modified respectively based on preset MBR partition table data definitions of inactive partitions and active partitions to obtain a first partition and a second partition, and the MBR partition table data is the type of the storage partition obtained by partitioning based on the MBR partition management system.

Referring to fig. 2, fig. 2 is a schematic view of a boot sector of an MBR partition management system according to an embodiment of the present disclosure.

The bootstrap sector schematic diagram shown in fig. 2 includes bytes in a bootstrap sector of the MBR partition management system, where the sector is 512 bytes, and includes: MBR boot program, DPT (Disk Partition Table), and a valid flag. Wherein, the first 446 bytes shown in FIG. 2 is the bootstrap; the frame selection area is 64 bytes of DPT, the DPT is MBR partition table data after partition of an MBR partition management system, each 16 bytes of DPT is used for describing one partition, namely, the 16 bytes in sequence of DPT can represent the type of each partition after partition; a two byte valid flag "55AA" is used to characterize whether the DPT is valid.

Thus, when configuring the first partition and the second partition, the DPT may be modified, thereby enabling the DPT to be used to characterize the type of memory partition.

As shown in fig. 2, the first partition is: 00 41 02 00 00FE FF 00 FF 10 00 00 00 00B0 B603. Wherein, byte 1, 0x00, indicates that the partition is an inactive partition, and byte 5, 0x00, indicates that the partition is not allocated, i.e. indicates that the partition is not used. Bytes 9-12, collectively representing a partition start sector number of 4096, and bytes 13-16, collectively representing a total number of sectors of a partition 62304256.

It is understood that the above description and the accompanying drawings are only examples, and when configuring a storage partition, the 1 st byte of the storage partition is configured as 00 and the 5 th byte of the storage partition is configured as 00, i.e. the partition can be characterized as an active partition and can be used for storing data.

With continued reference to fig. 2, the second partition is: 80FE FF 0B FF 01C0B 03 0050 00, wherein the 1 st byte 0x80 indicates that the partition is an active partition, the 5 th byte 0x0B indicates that the partition mounts the Fat standard file system, the 9 th to 12 th bytes collectively indicate that the partition start sector number is 62308353, and the 13 th to 16 th bytes collectively indicate that the total sector number of the partition is 20480 (10M).

The size 10M of the total number of sectors is only an example, and in actual setting, other sizes may be set according to needs.

In fig. 2, the divided storage partitions include only two partitions, and for other partitions, the other partitions may be reasonably set according to requirements and are not expanded here.

Referring to table 1, table 1 is a DPT byte meaning table provided in this embodiment, and when configuring a partition, the setting may be performed according to the DPT byte meaning table.

TABLE 1 DPT Byte implication Table

The DPT byte meaning table in table 1 reveals the meaning of a part of bytes, and for the configuration of other bytes in the DPT, the configuration can be set reasonably according to the requirement, and specific contents may refer to the prior art and are not described herein again.

Next, for the GPT partition management system, based on a preset GPT partition type definition for an inactive partition and an active partition, modifying the GPT partition types of different storage partitions respectively to obtain a first partition and the second partition. The GPT partition type can represent the type of a memory partition obtained by partitioning based on a GPT partition management system.

In this embodiment, in a plurality of storage partitions obtained by partitioning the GPT partition management system, each storage partition includes a plurality of sectors, each sector is 512 bytes, and a sector is usually represented by an LBA (Logical Block Address). Where LBA 0 represents the first sector, LBA-1 represents the last sector, and so on.

LBA 0 is the header of the GPT partition and can store a boot sector of the MBR to be compatible with the MBR partition management system. The 5 th byte of the boot sector DPT is a byte indicating that the GPT partition management system is used, for example, 0xEE.

The LBA 1 is used to characterize a partition table header, to define the available space of the hard disk and data such as the size and number of items constituting the partition table, and to store a check table, to determine whether the partition table is faulty, and to characterize the hard disk as unusable if the check is faulty.

LBA 2-33 is used to store partition table entries, and the 16 bytes of the default location of a partition table entry are used to indicate the partition type, i.e., the GUID value.

In the GPT partition management system, the GUID value of a partial partition type has its corresponding meaning, based on which a storage partition can be determined as a storage partition of the partition type to which the GUID value corresponds, and the meaning relationship of the GUID value can refer to the prior art, and is not expanded here.

Referring to fig. 3, fig. 3 is a schematic diagram illustrating partition types of a partition management system according to an embodiment of the present application.

In this embodiment, when configuring the first partition of the inactive partition, the GUID value of the partition type may be modified to have a value other than the corresponding meaning value, so that the meaning corresponding to the GUID value is allowed, and after the GUID value is identified, the continued identification is not performed. Thus, the partition may be configured as an inactive partition, and it may be determined to store data of the private file system for the first partition. As shown in fig. 3, 55 d … e 35 may be represented as a first partition.

It is understood that the inactive partition refers to a storage partition that is not recognized by other electronic devices, and therefore, in the present embodiment, the partition type of the inactive partition may not belong to the defined partition type, and the GUID value thereof may be any value that does not have a corresponding meaning.

In this embodiment, when the second partition of the active partition is configured, the GUID value of the partition may be configured to be the GUID value corresponding to the standard partition type, so that the partition may be normally identified, and after the standard file system is stored, it may be identified that the partition is mounted with the standard file system. As shown in fig. 3, A2 A0 … C7 may be represented as a second partition.

Therefore, the data of the private file system and the data of the standard file system can be stored in the corresponding positions of the first partition and the second partition respectively. When other electronic equipment detects the storage equipment of the target equipment, after detecting the GUID corresponding to the first partition, the other electronic equipment skips the first partition and continues to detect the subsequent storage partition, and when the GUID of the second partition is detected, the data in the second partition is identified and mounted so as to realize the read-write operation on the storage equipment of the target equipment.

Based on the same inventive concept, the embodiment of the application also provides a double-file implementation device. Referring to fig. 4, fig. 4 is a schematic structural diagram of a dual file system implementation apparatus according to an embodiment of the present disclosure, in which the dual file system implementation apparatus 200 includes a partition module 210, a configuration module 220, and a storage module 230.

The partitioning module 210 is further configured to determine that the GPT partition management system is the target partition management system when it is determined that the space capacity of the storage device is greater than the preset space threshold.

The configuration module 220 modifies the GPT partition types of different storage partitions respectively based on the preset GPT partition type definitions of the inactive partition and the active partition to obtain a first partition and a second partition, and the GPT partition type represents the type of the storage partition obtained by partitioning based on the GPT partition management system.
