A method for intelligently controlling defect storage data reading

Abstract

The invention discloses a method for intelligently controlling defective storage data reading. The method comprises the following steps of S1: sending a request; S2: waiting for receiving a synchronization signal; S3: reading data and correcting reading parameters in the data reading process; S4: going to the step S5 when data in a data region is read successfully, or otherwise, going to the step S7; S5: going to the step S6 if a state of a hard disk is not a busy state, or otherwise, going to the step S7; S6: setting a current mode as a high-speed mode and executing the step S8 when the consumed time is less than 20ms, or otherwise, going to the step S7; S7: resetting the hard disk and setting a reading speed as a low-speed mode; and S8: returning the successfully read data to an upper-layer interface for a user to view. The method has the beneficial effects that the hard disk states of the processed regions can be subjected to statistics, a bad sector defect state of the hard disk is monitored in real time during the reading process, the reading mode including the high-speed mode or the low-speed mode is corrected according to the defect state, the unit size of reading and the precision of one-time reading are adjusted, and the data reading efficiency is ensured while the data reading integrity is ensured.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for intelligently controlling defect storage data reading. Background technique [0002] At present, data interaction with defect virtual protection is required when searching for storage device partitions and file browsing data mirroring. Users generally choose the accuracy of data reading and the way to deal with bad sectors according to the conditions of the storage medium itself; but the defect status of the hard disk is not Invariably, a single static setting method can lead to unreadable data or inefficiency. Contents of the invention [0003] Aiming at the defects of the prior art, the present invention provides a method for intelligently controlling defect storage data reading, which can effectively solve the above-mentioned problems in the prior art. [0004] A method for intelligently controlling defect storage data reading, comprising the follo...
