Description

A kind of method of repairing Xi Shuo hard disk firmware district adaptation parameter module

Technical field

The present invention relates to field of information security technology, particularly a kind of method of repairing Xi Shuo hard disk firmware district adaptation parameter module.

Background technology

It is all carry out store data by the read-write of magnetic head that the data of hard disk store, and due under the accumulation of time and the impact of uncontrollable external cause, controls and drive the firmware of magnetic head easily impaired in hard disk.Cause the firmware adaptations invalidates information of the read-write adaptation of magnetic head, magnetic head cornice adaptation and read-write density adaptation.

The firmware district adaptation parameter module of western number hard disk is the key modules in firmware district, is present in the middle of western number hard disk ROM data body.If firmware district adaptation parameter module damage, can cause that hard disk occurs having no idea to read data, access makes mistakes, occur a large amount of red green piece of bad track, tracking is made mistakes, strike the problems such as dish and abnormal sound.

Prior art generally adopts the hard disk coupling relevant parameter of same train; Read out the firmware district adaptation parameter module of matching disc, reached the object of reparation by the firmware district adaptation parameter module of the outside matching disc of write-back.Use outside module to carry out adaptive faulty disk, usually there will be cannot the situation of adaptation completely.

Summary of the invention

The present invention is directed to the defect of prior art, propose a kind of method of repairing Xi Shuo hard disk firmware district adaptation parameter module, comprise the following steps:

S1: extract faulty hard disk user area adaptation parameter module data;

S2: according to the data recombination firmware district adaptation parameter module in the adaptation parameter module of user area;

S3: allotment JOG adaptation parameter.

As preferably, the detailed step of described S1 is as follows:

S101: the user area adaptation parameter module extracting faulty hard disk;

S102: judge whether to extract successfully, if then terminate, then performs S103 if not;

S103: the virtual magnetic track traveling through faulty hard disk in order, finds text ROYL position;

S104: judge that ROYL position offsets downward the head feature whether 8 bytes are user area adaptation parameter module, if then perform S105, if not then perform S103;

S105: offset 2 bytes backward according to adaptation parameter module head feature position, user area and obtain this block size.

As preferably, the detailed step of described S2 is as follows:

S201: the header data section obtaining firmware district adaptation parameter module in faulty hard disk ROM;

S202: obtain valid data reference position according to user area adaptation parameter module valid data head feature;

S203: the middle part valid data section calculating firmware district adaptation parameter module needs according to valid data reference position;

S204: obtain firmware district adaptation parameter module tail data section in ROM;

S205: the middle part valid data that the header data section obtain S201 and S203 obtain and the tail data section that S204 obtains form new firmware district adaptation parameter module;

S206: new firmware district adaptation parameter module data is written back to ROM and covers original firmware district adaptation parameter module data.

As preferably, the detailed step of described S3 is as follows:

S301: the address and the size that obtain the JOG parameter shift of faulty hard disk;

S302: from original JOG argument address head back skew, obtain JOG adaptation parameter value;

S303: JOG adaptation parameter is covered original JOG parameter.

Compared with prior art the invention has the advantages that: accurately can find out firmware district adaptation parameter module desired data, and firmware district adaptation parameter module of recombinating; The parameter of adjustable firmware district adaptation module reaches the object of repairing hard disk; Solve that hard disk tracking is made mistakes, struck dish, abnormal sound, can not read and write data the problems such as district, and there will not be after repairing cannot the problem of adaptation completely.

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 method of repairing Xi Shuo hard disk firmware district adaptation parameter module, comprises the following steps:

S1: extract faulty hard disk user area adaptation parameter module data;

S2: according to the data recombination firmware district adaptation parameter module in the adaptation parameter module of user area;

S3: allotment JOG adaptation parameter.

As shown in Figure 2, the detailed step of described S1 is as follows:

S101: the user area adaptation parameter module extracting faulty hard disk;

S102: judge whether to extract successfully, if then terminate, then performs S103 if not;

S103: the virtual magnetic track traveling through faulty hard disk in order, finds text ROYL position, and the redirect value of this position is " 524F5942 ";

S104: judge that ROYL position offsets downward the head feature whether 8 bytes are user area adaptation parameter module, described head feature is " 00 40 ", if then perform S105, if not then perform S103;

S105: offset 2 bytes more backward according to user area adaptation parameter module head feature " 00 40 " and obtain this block size.

As shown in Figure 3, the detailed step of described S2 is as follows:

S201: the header data section obtaining firmware district adaptation parameter module in faulty hard disk ROM, data segment size is 48 bytes;

S202: obtain valid data reference position according to user area adaptation parameter module head redirect " 0x1E ";

S203: the middle part valid data section calculating firmware district adaptation parameter module needs according to valid data feature reference position;

Here need first to determine that the structure of valid data initiation feature be 8 bytes be a feature or 4 bytes is a feature, the 3rd valid data initiation feature is gone to after determining structure, this feature and be the initiation feature of first valid data section, obtain valid data g. slice header at the first half by data segment feature, latter half obtains valid data section size.

Perform formula:

[the several number of logic magnetic head]=([JOG offset address size]-[Preamp address size])/[4];

[valid data section is overall]/[3]/[21]/[the several number of logic magnetic head]=[data segment];

The data segment size that we need is identical and number is identical with the several number of logic magnetic head; So need the position obtaining all data segments.

Perform formula:

[the little segment base of next data]=[a upper data segment size] * [21]+[a upper data segment start address];

The number of times performing this formula equals the several number of logic magnetic head, will obtain the middle part valid data section that the little segment record of each data also forms firmware district adaptation parameter module needs in order;

S204: obtain firmware district adaptation parameter module tail data section in ROM,

Perform formula:

[original firmware district adaptation parameter module]-[the middle part valid data section in S203]-[the header data section in S201]=[tail data section];

S205: the middle part valid data that the header data section obtain S201 and S203 obtain and the tail data section that S204 obtains form new firmware district adaptation parameter module;

S206: the firmware district adaptation parameter module data of restructuring is written back to ROM and covers original firmware district adaptation parameter module data.

As shown in Figure 4, the detailed step of described S3 is as follows:

S301: the address and the size that obtain the JOG parameter shift of faulty hard disk;

S302: from original JOG argument address head back skew, obtain JOG adaptation parameter value; Be somebody's turn to do [side-play amount]=[2 byte] * [the several number of logic magnetic head];

S303: JOG adaptation parameter is covered original JOG parameter.

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.
