Embodiment Construction

[0042] The method and device for adjusting the NTFS partition provided by the embodiments of the present application are used to adjust the size and / or position of the NTFS partition. Specifically, the adjustment instruction input by the user can be obtained through the manual interaction module, and the adjustment instruction is at least used to indicate the adjusted The size and location of the partition, and adjust the NTFS partition according to the adjustment command.

[0043] In the following embodiments of the present application, the partition before adjustment is called the original partition, and the partition after adjustment is called the adjusted partition. It should be noted that the expression "partition after adjustment" refers to the partition that can be obtained after the adjustment is successful, but it does not mean that the partition has been adjusted successfully after using this expression.

[0044] The following will clearly and completely describe the...

Abstract

The invention provides a method and device for adjusting an NTFS partition, and the method comprises the steps: copying data of a storage area which is included in an original partition and is not included in an adjusted partition to an idle area in the adjusted partition, building a first type of meta-files in the idle area, and building Boot at a first cluster of the adjusted partition. Comparedwith the prior art, the data in the original partition does not need to be integrally migrated; the data included in the original partition which is not adjusted is copied only in the idle area of the adjusted partition, and most of the metadata is established, so that the data and the metadata in the original partition are not changed, and the data and the metadata in the original partition cannot be lost under the condition that power failure occurs before adjustment is completed. In addition, due to the fact that the Boot is very small, the possibility of power failure in the process of establishing the meta-file is very small, and the possibility of data loss under the condition that partition adjustment is unsuccessful can be effectively reduced.

Description

technical field [0001] This application relates to the field of electronic information, in particular to a method and device for adjusting NTFS partitions. Background technique [0002] The Windows operating system supports the adjustment of the size of the NTFS partition, and the third-party disk management software supports the adjustment of the storage area and size of the NTFS partition. During the process of adjusting the storage area and / or size of the NTFS partition, if the power is turned off without the adjustment being successful, the partition structure will be destroyed, resulting in data loss. [0003] E.g figure 1 The figure shows the NTFS partition before adjustment, and the occupied space is from j to k. Assuming that the user adjusts the storage area of ​​the NTFS partition through the third disk management software, the adjusted partition is as follows: figure 2 As shown, the occupied space is j+1 to k+1. In the existing process of adjusting the storage...
