Embodiment 1

[0027] refer to figure 1 , a method for flash memory data protection and repair, comprising the following steps:

[0028] S1: Create different sector repositories and classify the sector repositories;

[0029] S2: input data for scanning and backup;

[0030] S3: compare and detect the data when scanning the data for the second time;

[0031] S4: Eliminate dangerous and useless data;

[0032] S5: Use the backup data to organize and repair the data;

[0033] S6: classify and store data into different sectors and set a security password.

[0034] In this embodiment, the sector storage library is classified in S1, classified according to time, memory size, and data type, and keywords, data virus templates, and regular data templates are pre-stored in the data input computer calculation.

[0035] In this embodiment, S2 inputs the data into the computer, reads the data when inputting the data, and backs up the read data according to the initial state.

[0036] In this embodime...

Embodiment 2

[0042] refer to figure 1 , a method for flash memory data protection and repair, comprising the following steps:

[0043] S1: Create different sector repositories and classify the sector repositories;

[0044] S2: input data for scanning and backup;

[0045] S3: compare and detect the data when scanning the data for the second time;

[0046] S4: Eliminate dangerous and useless data;

[0047] S5: Use the backup data to organize and repair the data;

[0048] S6: classify and store data into different sectors and set a security password.

[0049] In this embodiment, the sector storage library is classified in S1, classified according to time, memory size, and data type, and keywords, data virus templates, and conventional data templates are pre-stored in the data input computer calculation, and blank memory It is proposed that scanning can be avoided and data reading speed can be improved.

[0050] In this embodiment, S2 inputs the data into the computer, reads the data whe...

Abstract

The invention belongs to the technical field of flash memory data protection and restoration, particularly relates to a flash memory data protection and restoration method, and provides the following scheme aiming at the problems that the existing flash memory data is not provided with an intact protection and restoration method, hidden dangers are easily buried in a flash memory, and data missing is extremely easily caused. The method comprises the following steps: S1, creating different sector storage libraries, and classifying the sector storage libraries; s2, scanning input data and backing up; s3, performing comparison detection on the data when the data is scanned for the second time; s4, eliminating dangerous and useless data; s5, arranging and repairing the data by using the backup data; and S6, storing the data in different sectors in a classified manner, setting security passwords, and classifying the sector storage library in the step S1 according to time, memory size and data types. The invention is convenient to operate, the flash memory data can be protected and repaired, and data missing is avoided.

Description

technical field [0001] The invention relates to the technical field of flash memory data protection and restoration, in particular to a flash memory data protection and restoration method. Background technique [0002] Flash memory is a long-life non-volatile memory. Data deletion is not in units of individual bytes but in units of fixed blocks. The block size is generally 256KB to 20MB. Flash memory is electronically erasable only A variant of read memory (EEPROM), the difference between flash memory and EEPROM is that EEPROM can be deleted and rewritten at the byte level instead of erasing the entire chip, while most chips of flash memory need to be erased in blocks. Data can still be saved. Flash memory is usually used to save setting information. When flash memory is used, it will also be violated by external viruses and dangerous data, commonly known as implanted viruses, which may easily cause data loss and leakage. [0003] The existing flash memory data does not hav...
