[0018] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Figure 1 It is a flow chart of a partition table conversion method provided by an embodiment of the present invention. The embodiment of the present invention is applicable to the scenario of converting a GPT partition table into an MBR partition table. The method can be executed by a partition table conversion device, which can be implemented by software and / or hardware.

[0020] like Figure 1 As shown, the partition table conversion method includes the following steps:

[0021] S110, obtaining target GPT partition table data.

[0022] The target boot partition drive letter parameter may be identification information about the data to be converted. Exemplarily, the target boot partition drive letter parameter may be obtained by user input.

[0023] S120, converting the format of the target GPT partition table data based on a preset table conversion format to obtain a target MBR partition table.

[0024] The preset conversion format may be a conversion standard for converting the GPT format into the MBR format. Specifically, the preset table conversion format may be set manually. The target MBR partition table may be the MBR partition table finally obtained after the format conversion. Exemplarily, each item of data in the target GPT partition table data may be converted from the GPT format into the MBR format according to the preset table conversion format, thereby obtaining the target MBR partition table.

[0025] S130. Store the target MBR partition table in a preset partition to complete the format conversion process of the target GPT partition table data.

[0026] The preset partition can be a preset partition for storing MBR partition table data. For example, a specified sector in the target hard disk can be used as a preset partition, and the target MBR partition table is finally stored in the preset partition, so that the target MBR partition table can be retrieved from the preset partition in a timely manner.

[0027] The technical solution provided by the embodiment of the present invention obtains the target GPT partition table data; performs format conversion on the target GPT partition table data based on a preset table conversion format to obtain the target MBR partition table; wherein the preset table conversion format is used to convert the data from the GPT format to the MBR format; and the target MBR partition table is stored in a preset partition to complete the format conversion process of the target GPT partition table data. The technical solution of the embodiment of the present invention solves the problem of data loss and cumbersome operation steps in the process of converting the GPT partition table to the MBR partition table in the prior art, and can quickly and automatically realize the conversion of the GPT partition table to the MBR partition table without data loss, thereby improving the efficiency and accuracy of data conversion and providing support for the whole machine migration product.

[0028] Figure 2 It is another partition table conversion method flow chart provided by an embodiment of the present invention. The embodiment of the present invention can be applied to the scenario of converting a GPT partition table into an MBR partition table. Based on the above embodiment, this embodiment further illustrates how to obtain the target GPT partition table data; and how to convert the format of the target GPT partition table data based on a preset table conversion format to obtain a target MBR partition table. The device can be implemented by software and / or hardware and integrated in a computer device with application development function.

[0029] like Figure 2 As shown, the partition table conversion method includes the following steps:

[0030] S210, obtaining drive letter parameters of the target boot partition.

[0031] The target boot partition drive letter parameter may be identification information about the data to be converted. Exemplarily, the target boot partition drive letter parameter may be obtained by user input.

[0032] S220. Based on the target boot partition drive letter parameter, read sector data from the second sector in the target hard disk, and determine the target GPT partition table data according to the sector data.

[0033] Wherein, the target hard disk may be a hard disk for storing conversion data. Wherein, the target hard disk may include a first sector and a second sector. Wherein, the first sector may be a sector for storing MBR partition table data. The second sector may be a sector for storing GPT partition table data. Specifically, the sector data corresponding to the target boot partition drive letter parameter may be matched from the second sector of the target hard disk, and then the target GTP partition table data may be determined based on the matched sector data. Wherein, the target GPT partition table data may be partition table data that needs to be formatted. The technical solution of the embodiment of the present invention requires converting the target GPT partition table data from the GPT format to the MBR format.

[0034] Optionally, obtaining the target GPT partition table data includes: obtaining a target boot partition drive letter parameter; based on the target boot partition drive letter parameter, reading sector data from a second sector in the target hard disk, and determining the target GPT partition table data according to the sector data.

[0035] Among them, the preset GPT partition header type can be a preset table entry type contained in the GPT partition table. Specifically, the preset GPT partition header type can be set manually. The partition header data can be the header type data contained in the sector data. Specifically, according to the preset GPT partition header type, the corresponding header type data can be matched from the sector data, and the matched header type data can be used as the partition table data. Furthermore, the partition data can be specific parameter data corresponding to the partition header data. After determining the partition header data, the specific parameter data under the header type data name can be used as the partition data corresponding to the partition header data.

[0036] Furthermore, the target GPT partition table data may be the GPT partition table data that needs to be formatted. Exemplarily, a GPT partition table may be constructed, and then the partition table header data may be filled into the table header item of the partition table, and the partition data may be filled into the data column corresponding to the table header item, and the GPT partition table after the data filling is completed may be used as the target GPT partition table data.

[0037] S230: Determine the partition table item association relationship according to the preset table conversion format.

[0038] Among them, the preset conversion format can be a conversion standard for converting the GPT format into the MBR format. Specifically, the preset table conversion format can be set manually. Further, the partition table item association relationship is used to represent the association relationship between the GPT partition table item and the MBR partition table item. The GPT partition table item can be a table item in the GPT partition table. Specifically, the GPT partition table item can be understood as the partition table header of the GPT partition table described above. The MBR partition table item can be a table item in the MBR partition table. Specifically, the correspondence between each GPT partition table item and the MBR partition table item can be determined according to the preset table conversion format, thereby obtaining the partition table item association relationship.

[0039] S240. According to the partition table item association relationship, the target GPT partition table data is formatted to obtain a target MBR partition table.

[0040] The target MBR partition table may be the MBR partition table finally obtained after format conversion. Specifically, each partition data item in the target GPT partition table data may be format converted according to the partition table item association relationship to obtain the target MBR partition table.

[0041] Optionally, according to the association relationship of the partition table items, the target GPT partition table data is formatted to obtain the target MBR partition table, including: creating an initial MBR partition table; for each GPT partition table item in the target GPT partition table data, based on the association relationship of the partition table items, determining the corresponding MBR partition table item from the initial MBR partition table; filling the partition data of the GPT partition table item into the filling column corresponding to the MBR partition table item to obtain the target MBR partition table. The initial MBR partition table may be an MBR partition table without data filling. The MBR partition table item includes at least one of: an active partition, a starting CHS (sector) address, a partition type, an ending CHS address, a starting LBA (logical block address), and a partition occupancy.

[0042] S250: Store the target MBR partition table in a preset partition to complete the format conversion process of the target GPT partition table data.

[0043] The preset partition may be a preset partition for storing MBR partition table data. Exemplarily, the first sector in the target hard disk may be used as the preset partition.

[0044] Optionally, storing the target MBR partition table in a preset partition includes: acquiring partition table entry data in the target MBR partition table, and storing the partition table entry data in a first sector of the target hard disk.

[0045] For example, in order to better understand the technical solution provided by the present invention, a specific embodiment is introduced below. The specific implementation of this technology is generally divided into three steps:

[0046] First, read the boot disk sector to obtain the partition table and format the partition table data. First, the program needs to obtain the boot partition drive letter parameters, and read the corresponding hard disk sector data according to the drive letter parameters. This tool converts the GPT partition table into the MBR partition table, so it needs to read the second sector of the boot partition. Then read the partition table header and all partition information according to the definition of the GPT partition table, and save this information into the structure.

[0047] Second, convert the partition table according to the data structure obtained in the above steps. After extracting the key information, the information required by the MBR partition table is converted into the format of the MBR partition table. Therefore, it is necessary to convert the sector information of the partition table into a format, and convert it into status marks in sequence, namely whether it is an active partition, the starting CHS address, the partition type, the ending CHS address, the starting LBA and the partition occupancy. Then fill this information into each MBR partition table entry.

[0048] 3. Write the MBR partition table entry to the location of the first sector partition table of the disk.

[0049] The technical solution provided by the embodiment of the present invention obtains the target boot partition drive letter parameter; based on the target boot partition drive letter parameter, reads the sector data from the second sector in the target hard disk, and determines the target GPT partition table data according to the sector data; determines the partition table item association relationship according to the preset table conversion format; performs format conversion on the target GPT partition table data according to the partition table item association relationship to obtain the target MBR partition table; stores the target MBR partition table in the preset partition to complete the format conversion process of the target GPT partition table data. The technical solution of the embodiment of the present invention solves the problem of data loss and cumbersome operation steps in the process of converting the GPT partition table to the MBR partition table in the prior art, and can quickly and automatically realize the conversion of the GPT partition table to the MBR partition table without data loss, thereby improving the efficiency and accuracy of data conversion and providing support for the whole machine migration product.
