Embodiment Construction

[0044] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0045] A data recovery method in which the physical problems of the Western Digital hard disk lead to parameter identification errors, such as figure 1 as shown,

[0046] 001 Obtain the ROM file on the circuit board of the faulty disk;

[0047] 002 Write the obtained ROM file into the ROM file on the circuit board of the accessory disk, where the circuit board numbers of the accessory disk and the faulty disk must be the same;

[0048] 003 Connect the circuit board of the accessory disk that has written the ROM file of the faulty disk to the disk body of the faulty disk for data recovery.

[0049] Such as figure 2 As shown, 001 includes the following steps:

[0050] If the 101 hard disk is in normal use, if the ROM file of the hard disk is backed u...

Abstract

The invention discloses a data recovery method of a parameter identification error caused by Western digital hard disk physical problems, and belongs to the technical field of the data recovery. The method comprises the following steps that firstly, an ROM file on a circuit board of a malfunction disk is obtained; secondly, the obtained ROM file is programmed into an ROM file on a circuit board of an accessory disk, the circuit board number of the malfunction disk and the circuit board number of the accessory disk must be same; thirdly, the circuit board of the accessory disk of the ROM file which is programmed into the malfunction disk is connected to a disk body of the malfunction disk, and data recovery is carried out. The method has the advantages that an ROM file can be generated from the disk body, and firmware needed by the generated ROM file is obtained through heat exchanging, the data recovery can be effectively carried out on the parameter identification error caused by the Western digital hard disk physical problems.

Description

technical field [0001] The invention belongs to the field of data recovery, and in particular relates to a data recovery method for parameter identification errors caused by physical problems of Western Digital hard disks. Background technique [0002] Because the FLASH memory chip (also called ROM) on the circuit board stores information including the distribution information of the specified magnetic heads, the number of magnetic heads, and the number of disks, the FLASH chip is very important in Western Digital hard drives. Only one circuit board (not including the disk body) is needed, and the computer can identify the model of the hard disk after a certain period of time. [0003] Improper use of Western Digital hard drives usually leads to failure of the circuit board. If the components on the circuit board burn out and lead to an open circuit, the hard drive will fail to start; if the ROM chip fails to read, it will appear that the hard drive starts normally. Turn, r...
