Embodiment Construction

[0034] In order to explain in detail the technical content, structural features, achieved goals and effects of the technical solution, the following will be described in detail in conjunction with specific embodiments and accompanying drawings.

[0035] see figure 1 , a flow chart of a method for quickly programming data to an EXT partition according to an embodiment of the present invention. The method can be run on an electronic device with computing and processing functions, and the electronic device can be a host computer, such as a computer. The host computer specifically includes the following steps when burning data to the EXT partition:

[0036] First enter step S101, according to the capacity of the EXT partition, the data to be burned is generated as an image file in the format of the EXT partition. The image file can be stored on the hard disk of the host computer for subsequent operation. Such as image 3 As shown, the image file includes a plurality of block g...

Abstract

The invention provides a method and a device for quickly programming data to an EXT partition. According to the method, a corresponding image file is generated according to the actual size of the EXT partition, and during programming, erasure processing is performed on the whole partition first, and a whole block group of data blocks where data is stored is programmed; only super blocks and a block group descriptor of a block group, meeting a first preset condition, of data blocks where data is not stored are programmed; and a block group, not meeting the first preset condition, of data blocks where data is not stored is not programmed. Compared with the mode of programming the whole image file (that is, all block groups are programmed one by one), through the scheme, the programmed data volume is greatly reduced, meanwhile, Resize operation does not need to be performed on the partition during first start, and therefore the scheme is beneficial for improving programming efficiency.

Description

technical field [0001] The invention relates to the field of computer technology security, in particular to a method and device for quickly burning data to an EXT partition. Background technique [0002] At present, there are mainly two methods for burning data to an unformatted EXT partition: the first is to generate an image file with customized content according to the actual size of the EXT partition, and then burn the image file to the EXT partition. Since the generated image files are often large, the burning time is long and the burning efficiency is low. The other is to generate an image file according to the size of the customized content to be burned, and then burn the generated image file to the EXT partition. With this method, the EXT partition needs to be resized at the first startup, which will seriously affect the first startup time. Contents of the invention [0003] Therefore, it is necessary to provide a technical solution for quickly burning data to th...
