CN104851465A - Method for repairing access fault and slow running of western digital hard disk - Google Patents

Abstract

The invention discloses a method for repairing the access fault and slow running of a western digital hard disk and belongs to the technical field of data recovery. The method comprises the following steps: 001, repairing by aiming at the conditions that the hard disk has overall bad sector, and data can be not be read; and 002, repairing again aiming at the condition that the hard disk is slow in response after being repaired in the step 001. The method has the beneficial effects that 1, the aim of removing a G table is achieved by writing back in a G table module without items, and the fault that the hard disk can be identified, but can not be accessed can be overcome by removing the G table; 2, the problem that the hard disk is slow in response can be solved by deleting error log information.

Description

Restorative procedure slowly be accessed and be run to western number hard disk cannot

Technical field

The invention belongs to date restoring field, be specifically related to a kind of western number hard disk and cannot access and run restorative procedure slowly.

Background technology

Hard disk has used of a specified duration just may there is various problem, and hard disk " bad track " is this wherein modal problem.Hard disk occurs that bad track is except the quality of hard disk own and aging reason, mainly hard disk can not be treated kindly at ordinary times in use, such as internal memory very little so that application software hard disk is frequently accessed, to the undue defrag continually of hard disk, unsuitable overclocking, power quality is bad, and temperature is too high, dust-proof bad, vibrations etc.

Each new hard disk just dispatched from the factory more or less there is bad track, only they by producer be hidden in P table and G show in, with general softward interview less than it.G shows, and also known as user class list, approximately can deposit hundreds of the bad track to about 1,000; P shows, also known as factory level list, and can the bad track that about 4000 be deposited or more.When maintenance, software usually can be used to carry out bad track scanning to hard disk, can not be real overall bad track usually, but the faults such as firmware cause hard disk to occur the situation of inaccessible when there is overall bad track when scanning.

In addition, in use, to there will be response speed very slow for hard disk; when reparation the problems referred to above; the mode that people usually can select low lattice or totally reset, this mode is also can not be successful certainly, because the situation of inaccessible has appearred in hard disk.

Explanation of nouns:

UBA (Unit Block Address, cell block addressing);

LITTLE-ENDIAN (little-endian, low byte sequence), corresponding is BIG-ENDIAN (large syllable sequence, high byte sequence) with it.

Summary of the invention

The present invention is directed to the deficiencies in the prior art; provide a kind of western number hard disk and cannot access and run restorative procedure slowly; effectively can solve Xi Shuo hard disk firmware district fault causes hard disk to be identified; but data can not be accessed or can be accessed, but the velocity sag problem slowly of access.

For overcoming the above problems, the technical solution used in the present invention is as follows: restorative procedure slowly be accessed and be run to a kind of western number hard disk cannot, comprises the following steps:

001 there is overall bad track for hard disk, and the situation that data can not read is repaired;

002 repair hard disk for step 001 after respond situation slowly and again repair.

As preferably,

001 concrete grammar is as follows:

No. 34 modules of 101 acquisition hard disks, No. 34 modules are that G shows module;

102 open G shows module, G is shown module and resets, and former check code is revised as new check code;

G after amendment is shown module by 103 to be written back on hard disk.

As preferably,

101 concrete grammars are as follows:

1011 read G shows module, reads and successfully forwards end to, otherwise forward 1012 to;

1012 find the accessory tray that a model is all identical with faulty disk with firmware version number;

1013 G reading accessory tray show module.

As preferably,

102 concrete grammars are as follows:

1021 open G shows module, navigates to offset address 0x06 place, takes out 2 bytes according to the method for LITTLE-ENDIAN, and this value is the address that G table module contents starts;

1022 all reset from the address that G shows module contents to ending segment data;

1023 four bytes from the 0x0C address that G shows module are that G shows the check code of module, generate new check code, by new check code write herein after resetting.

As preferably,

002 concrete grammar is as follows:

No. 02 module of 201 acquisition hard disks, No. 02 module is parameter module;

202 open parameter module, the content of parameter module log region section reset, and former check code is revised as new check code;

Parameter module after amendment is written back on hard disk by 203.

As preferably,

201 concrete grammars are as follows:

2011 read parameter module, read and successfully forward end to, otherwise forward 2012 to;

2012 find the accessory tray that a model is all identical with faulty disk with firmware version number;

The parameter module of 2013 reading accessory tray.

As preferably,

202 concrete grammars are as follows:

2021 open parameter module, navigate to address, log region 0x4F4444 to 0x010028;

2022 by the zeros data of parameter module from 0x4F4444 to 0x010028 in address field, but not containing two end values;

Four bytes that the 0x0C address of 2023 parameter modules starts are the check code of parameter module, generate new check code after resetting, by new check code write herein.

Beneficial effect of the present invention is as follows:

1. do not have the G of entry to show module to reach the effect of removing G table by write-back, solve hard disk by removing G table and can identify but fault that can not be accessed;

2. solve hard disk by the log information of deletion error and respond problem slowly.
