Abstract

The invention discloses a data processing method for a hidden partition and electronic equipment, and the method comprises the steps: under the condition that both a fixed partition and a hidden partition in a hard disk are enabled, storing first partition information of the hard disk in a first logic unit group and a first backup unit group of a hard disk partition table, the hard disk partition table is arranged in a preset storage area in the hard disk; exporting the data stored in the first logic unit group to generate a corresponding first export file; under the condition that the hidden partition is started again after being closed, performing first verification on the data stored in the first backup unit group by utilizing the first export file; under the condition that the first verification is passed, respectively writing data stored in the first backup unit group into corresponding positions in the first logic unit group so as to update the first logic unit group; and accessing the hard disk by using the updated data stored in the first logic unit group. According to the method, the hidden partition can be normally used.

Description

technical field [0001] The present application relates to the field of hard disk control of electronic devices such as computers, and in particular, to a data processing method and electronic device for hidden partitions. Background technique [0002] The hard disks of electronic devices such as computers, such as NVMe SSD hard disks, have normal fixed partitions, and can also realize the function of hiding some LBAs, thus forming a hidden partition on the NVMe SSD disk. After the hidden partition is divided, it is invisible to the upper-layer software such as BIOS and OS, which can realize the purpose of data protection by using the hidden partition, and the hidden partition can prevent viruses and prevent the data in the hard disk from being illegally accessed or lost. . [0003] The partition information of the hard disk will be stored in both the start address segment (the first logical unit group) and the end address segment (the first backup unit group and / or the seco...
