Abstract
The present invention discloses a western digital hard disk repair method which comprises the following steps of: S1, analyzing magnetic head bitmap information by an acquired map module; S2, modifying the bitmap information and shielding damaged magnetic heads; and S3, loading a No.11 module matched with a microcode into a cache, loading an ATA to enable a hard disk to normally run and writing back to enable the hard disk to normally access main firmware of data. The western digital hard disk repair method has the beneficial effects that the damaged magnetic heads are forbidden to work by using a shielding method so as to prevent a disk from being damaged again; and by checking and reconstructing an effective data part of a magnetic head bitmap and the integral map module and finally loading the No.11 module to the cache in a microcode matching manner, the aim of enabling a damaged disk motor to run up and normally work is fulfilled, the fund cost of replacing the magnetic head is reduced, the stability of repairing the hard disk is improved and the repair success rate is higher. The magnetic heads with serious bad tracks are closed by the magnetic head bitmap, so that the disk knocking phenomenon is avoided in the powering-on process, the hard disk can be normally tracked and the problems of abnormal sound, continuous rotation and the like can be avoided.
Description
Technical field
The present invention relates to field of information security technology, particularly one western number Hard Disk Repair method.
Background technology
The western number hard-disk capacity 500G at least that society of today circulates, 2000G at most.These jumbo hard disks all need multiple magnetic head read and write hard disc and store data.In the production and life of reality, long read-write operation, the life-span of hard disc magnetic head more or less can weaken, and bad track may be caused thus to produce, and causes hard disk to strike the generation of dish phenomenon.Once strike dish, hard disk may be caused normally to seek, load hard disk firmware, finally causing cannot access hard disk Data Area data.This method is avoided damaging magnetic head work by the method for Use Adjustment magnetic head bitmap, thus hard disk can be allowed to use other good heads to visit firmware district, and the method reading firmware district firmware recovers hard disc data.
Illustrate about technical term herein:
Mapping module: the memory location of each module in firmware district is recorded in mapping module.
Summary of the invention
The present invention is directed to the defect of prior art, provide a kind of western number Hard Disk Repair method, effectively can solve above-mentioned prior art Problems existing.
In order to realize above goal of the invention, the technical scheme that the present invention takes is as follows:
A kind of western number Hard Disk Repair method, comprises the following steps:
S1: obtain ROM from hard disk circuit board, and from ROM analytic map module, from the mapping module obtained, resolve magnetic head message bit pattern;
S2: amendment message bit pattern, shields bad magnetic head;
S3: No. 11 module loading of being mated by microcode, to buffer memory, load ATA and hard disk is normally run up, and write-back makes the Main firmware of the normal visit data of hard disk energy.
The detailed step of described S1 is as follows:
S101: obtain western number hard disk ROM by ATA instruction;
S102: the data in retrieval ROM, searching map module head feature, this feature locations offsets 5 byte locations backward and finds mapping module reference position, in the position offseting 2 byte locations backward and find record mapping module size;
S103: scan entirely module according to the mapping module size of S102 and reference position, map block head " 0x06 " byte is mapping module valid data reference positions, this position can obtain valid data length, find the magnetic head message bit pattern of mapping module, magnetic head message bit pattern comprises physics magnetic head number information, the magnetic head number information, the message bit pattern used that use and records default message bit pattern.
As preferably, the detailed step of described S2 is as follows:
S201: according to head test result, finds magnetic head and the bad track of damage;
S202: the magnetic head that shielding damages, performs formula:
The magnetic head number of the magnetic head number of the magnetic head number used-bad=revise;
The bitmap numerical value used is comprehensive-the bitmap numerical value of the bitmap numerical value that damages=revise;
Then last 2 bytes of verification write are covered old verification, allow the magnetic head bitmap of amendment come into force by S203: perform 0x10000-valid data byte summation=valid data proof test value;
S204: whole magnetic head mapping module is effectively verified, and the position check code write head mapping module head back of 4 bytes being offset 12 bytes.
As preferably, the checking algorithm of verification is as follows:
S2041: establish variable: effect Value Data and, proof test value compose initial value 0;
S2042: data to be tested for magnetic head mapping module are divided into N part according to 4 bytes: N=firmware district sector length * 512/4;
S2043: the DWORD type signless integer sum calculating every a 4 bytes, assignment to data and;
S2044: perform formula: proof test value=0x100000000-data and;
S2045: after converting verification Value Data to 4 bytes, according to low front high rear arrangement.
As preferably, the detailed step of described S3 is as follows:
S301: load same microcode ATA, by checking the microcode of 4F module in ROM, 11 modules finding an energy consistent with microcode in the 4F module of faulty disk from other good dishes, and by 11 consistent for microcode module loading to damaging in hard disk cache;
S302: make to make good use of the Main firmware that head read makes the normal visit data of hard disk energy, and by Main firmware backup in other storage mediums;
S303: write-back Main firmware is to magnetic track again, the write-back S302 main modular that backs up out is to magnetic track again.Mainly there is the impaired place of bad track to allow, again writing with a brush dipped in Chinese ink the structure of a main modular, hard disk self can be detected by verification.
Compared with prior art the invention has the advantages that: use screen method to forbid damaging magnetic head work, prevent from again damaging disc, magnetic head bitmap valid data part and entirely module is rebuild by verification, finally by the mode of coupling microcode, by 11 module loading to buffer memory, reach low-quality disk motor and to run up the object of normal work, reduce the fund cost changing magnetic head, improve the stability of repairing hard disk, reparation has higher success rate.Close the serious magnetic head of bad track by magnetic head bitmap, avoid power-up procedures to strike dish, normally can seek, abnormal sound not occur, the problems such as not stall.
