Embodiment Construction

[0020] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0021] One of the core concepts of the embodiments of the present invention is that when it is necessary to perform a write operation on the protected partition, enter the abnormal boot mode, create a second directory, and mount the protected partition to the second directory in a read-write manner. In the directory, the write operation to the protected partition is realized through the operation of the second directory. The operation is simple, and no additional equipment such as a computer is required, which reduces user costs. Moreover, since the write operation is only performed in abnormal boot mode, avoiding The user accidentally erases the data in the protection partition and the device cannot be used normally, which improve...

Abstract

The invention provides a method and a device for executing write operation on a protected partition. The protected partition is a partition which is mounted in a first catalogue in a read only way in a normal starting mode, wherein the first catalogue is established in the normal starting mode; the method comprises the steps of when the write operation is needed to be carried out on the protected partition, entering the normal starting mode, establishing a second catalogue, and mounting the protected partition into the second catalogue in a read-write way; carrying out the write operation on the second catalogue in an abnormal starting mode. After the method and the device are adopted, the problem that equipment can not be normally used due to the complicated operation or misoperation when the write operation is carried out on a protected partition can be solved.

Description

technical field [0001] The invention relates to the technical field of disk data processing, in particular to a method for performing write operations on a protected partition and a device for performing write operations on the protected partition. Background technique [0002] Generally speaking, a storage device can be divided into multiple partitions (volume). For the Linux system, the partition can only be used by mounting it in a directory. The operation of this directory in the future is the operation of this partition, so that the unification of hardware management means and software directory management means is realized. [0003] Because some partitions store important data or confidential data that needs to be protected, the partition cannot be erased at will. When it is necessary to erase the partition with security protection, the following methods can be used: [0004] 1. Use special software installed on the computer (such as a burning tool) to write and erase...
