Data recovery system and method

Abstract

A data recovery system is used for automatically recovering initial system parameters when system parameters of electronic equipment are deleted by mistake. The electronic equipment comprises a memorizer used for storing the system parameters and verification codes, the system parameters and the verification codes are arranged at fixed positions of the memorizer respectively during the initialization of the electronic equipment by a parameter arranging program of the electronic equipment, the system parameters are endowed with first default values and the verification codes are endowed with second default values, the data recovery system comprises an acquisition unit, a judging unit and a data recovery unit, wherein the acquisition unit is used for reading the verification codes from the memorizer during the starting up of the electronic equipment; the judging unit is used for judging whether the read values of the verification codes are the second default values or not; the data recovery unit is used for recovering the system parameters inside the memorizer to be first default values when the judging unit determines that the read values of the verification codes are not the second default values. The invention further provides a data recovery method.

Description

technical field [0001] The present invention relates to a data recovery system and method, in particular to a data recovery system and method for recovering system data when system data is accidentally deleted. Background technique [0002] In current electronic equipment, important system parameters are all stored in the memory of the electronic equipment. When the operating system of the electronic equipment needs the system parameters, the corresponding parameters can be read from the memory. If the above-mentioned system parameters need to be modified during the setting process of the electronic device, the electronic device will write corresponding updated data into the memory. However, due to abnormal power failure or voltage instability, the command to change the system parameters of the memory will be misidentified as a clear command, causing some data in the memory to be deleted by mistake and cause errors, thereby affecting the work of electronic equipment. Taking...

However, due to abnormal power failure or voltage instability, the command to change the system parameters of the memory will be misidentified as a clear command, resulting in some data in the memory being deleted by mistake and causing errors, which will affect the work of electronic equipment.

Taking a DVD player as an example, when the system parameters are wrong, it is easy to cause black screen, blurred screen, no audio or video output and other abnormal phenomena when the DVD player is turned on, which brings great inconvenience to users.
