Abstract
The invention discloses a method for repairing a Western Digital hard disk unable to access data. The method is characterized by comprising the following steps: S1, selecting a matching disk; S2, extracting firmware module information of a fault hard disk; and S3, re-establishing an internal memory environment of the fault hard disk. Through the method, the process of repairing the hard disk is fast and efficient, and the repairing success rate is high; the problems that the hard disk firmware area is damaged, the hard disk has no data recovery in ATA status and the hard disk cannot be read can be solved, and the problems of abnormal friction or vibration and incompatibility between the repaired hard disk and a magnetic head can be avoided.
Description
Technical field
The present invention relates to field of information security technology, particularly a kind of repair western number hard disk cannot the method for visit data.
Background technology
In use, the impact due to not specific factor can cause the important module of hard disk to be damaged and make hard disk cannot normal visit data western number hard disk.Now, prior art can adopt some plain modes to process this problem, such as, with changing circuit board, but after this kind of repair mode reparation hard disk there will be access the sector response time slack-off, cannot directly access sector and strike the problems such as dish.
Summary of the invention
The present invention is directed to the defect of prior art, propose a kind of repair western number hard disk cannot the method for visit data, comprise the following steps:
S1: mate the model of normal hard disk, circuit board model, firmware version number and rom version number, chooses normal hard disk closest to faulty hard disk as matching disc;
S2: the firmware module information extracting faulty hard disk;
S3: the memory environment re-establishing faulty hard disk.
As preferably, the detailed step of described S2 is as follows:
S201: matching disc is opened electricity, stops hard disk motor after making firmware loads to hard disk cache, in energising situation, take off hard disk circuit board;
S202: the circuit board taking off faulty hard disk, is mounted to faulty hard disk by the circuit board of matching disc;
S203: faulty hard disk opens electricity, the magnetic head firmware module of backup harddisk, disc defects firmware module and magnetic head cornice height firmware module are to local disk;
S204: the power supply of disengagement failure hard disk.
As preferably, if the institute performing S2 in steps in matching disc occur that power down or disk state do, then need to re-execute S2.
As preferably, the detailed step of described S3 is as follows:
S301: the circuit board pulling down faulty hard disk is reinstalled matching disc, and matching disc opens electricity;
S302: the firmware module data of backup are write to matching disc and cover legacy data;
S303: again open electricity after power-off, stops hard disk motor after making firmware loads to hard disk cache;
S304: pull down circuit board and reinstall faulty hard disk, opens hard disk motor and reads data.
Compared with prior art the invention has the advantages that: the process ensureing to repair hard disk is quick and efficient, and reparation success ratio is high; Can process that hard disk firmware district damages, hard disk do not have the date restoring of ATA state, hard disk not to recognize the problem of dish, there will not be hard disk after repairing to strike dish and the problem such as not adaptive.
Accompanying drawing explanation
Fig. 1 is the main flow chart of the embodiment of the present invention;
Fig. 2 is the detail flowchart of step S2 of the present invention;
Fig. 3 is the detail flowchart of step S3 of the present invention.
Embodiment
In order to describe the specific embodiment of the present invention in detail, illustrate below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of repair western number hard disk cannot the method for visit data, comprise the following steps:
S1: mate normal hard disk and faulty hard disk, wherein Model model and R/N circuit board model, need completely the same; If need increase normal hard disk and the coupling degree of compatibility of faulty hard disk also need S/N sequence number front 4 consistent, before No. WWN 8 consistent, No. DCM the 3rd start rear 5 consistent.
In hard disk 0D ROM module, 0x20 to 0x27 position is firmware version number, mates this firmware version number.
In hard disk 4F module, 0x10 ~ 0x17 position is rom version number, coupling rom version number.
Choose normal hard disk closest to faulty hard disk as matching disc.
S2: the firmware module information extracting faulty hard disk;
S3: the memory environment re-establishing faulty hard disk.
As shown in Figure 2, the detailed step extracting the firmware module information of faulty hard disk is as follows:
S201: matching disc is opened electricity, stops hard disk motor after making firmware loads to hard disk cache, in energising situation, take off hard disk circuit board;
S202: the circuit board taking off faulty hard disk, is mounted to faulty hard disk by the circuit board of matching disc;
S203: faulty hard disk opens electricity, the magnetic head firmware module of backup harddisk, disc defects firmware module and magnetic head cornice height firmware module are to local disk.The module that need back up is specially: 0031 defect master meter module, 0032 RBBlist decoding table module, 0040 surface data adaptation module, 0041 surface data adaptation module and 00C4 magnetic head cornice height firmware module.
S204: the power supply of disengagement failure hard disk.
If occur in above-mentioned steps, matching disc occurs that power down or disk state do, then need to re-execute in steps.
As shown in Figure 3, the detailed step re-establishing the memory environment of faulty hard disk is as follows:
S301: the circuit board pulling down faulty hard disk is reinstalled matching disc, and matching disc opens electricity;
S302: the firmware module data backed up in S203 are write to matching disc and cover legacy data;
S303: again open electricity after power-off, stops hard disk motor after making firmware loads to hard disk cache;
S304: pull down circuit board and reinstall faulty hard disk, opens hard disk motor and reads data.
More than describe and set forth detail to fully understand the present invention, but the present invention can also adopt other to be different from this describing mode to implement, therefore the present invention is not limited to above disclosed concrete enforcement.
