Problems solved by technology

This kind of unrecognized disk is generally caused by the failure of Western Digital hard disk to access the hard disk firmware; in order to quickly repair, it is necessary to read and read the hard disk firmware area map accurately, so as to quickly locate other firmware modules to repair the unrecognized disk fault. However, the current existing technology cannot quickly locate the location of the module during the repair process, resulting in a long time to repair the hard disk

Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the following examples are given to further describe the present invention in detail.

[0039] Such as figure 1 As shown, a method of repairing the Western Digital hard drive not recognized, the specific steps are as follows:

[0040] S1: Read the ROM chip data body on the hard disk PCB board, the size is 256KB.

[0041] S2: Analyze the ROM chip data body to find the 0B module and extract its data. The detailed steps are as follows:

[0042] S21: sequentially retrieve the module header feature "0x52 4F 59 4C" in the ROM chip data body;

[0043] S22: After retrieving the feature of the module header, offset the feature by 4 bytes backwards, and then take 2 bytes of data, and these 2 bytes represent the feature of the ROM module number;

[0044] S23: Determine whether the module number data is "0x0B 00" (confirm whether it is a 0B module); if yes, execute S24, if not, execu...

Abstract

The present invention discloses a method for solving unidentification of a western digital hard disk. The method comprises a first step of reading a read-only memory (ROM) chip data body on a hard disk printed circuit board (PCB); a second step of analyzing the ROM chip data body to find out an OB module and extract the data body of the OB module; a third step of analyzing the OB module, and acquiring a UBA address of a firmware region module map; and a fourth step of positioning the module according to the UBA address . The method has the beneficial effects of recovering data in the hard disk even if the hard disk is unrecognized; accurately positioning a firmware map; and rapidly finding physical positions of other firmware through calculation, having high success rate in recovering hard disk data, and reducing the loss caused by hard disk damage.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a method for repairing an unrecognized Western Digital hard disk. Background technique [0002] Western Digital hard drives are one of the most widely used and widely branded hard drives on the market. According to market feedback, the latest hard drives produced by Western Digital manufacturers after 2012 may fail to recognize the hard drive after a period of use. [0003] In this case, the components of most Western Digital hard drives are still intact. This kind of unrecognized disk is generally caused by the failure of Western Digital hard disk to access the hard disk firmware; in order to quickly repair, it is necessary to read and read the hard disk firmware area map accurately, so as to quickly locate other firmware modules to repair the unrecognized disk fault. However, the current existing technology cannot quickly locate the location of the module during ...
