Abstract

The invention discloses a kind of western number hard disk can not access and run slow restorative procedure, belongs to data recovery technique field, comprises the following steps：001 there is overall bad track for hard disk, and the situation that data can not be read is repaired；002 is repaired again for responding slow situation after step 001 reparation hard disk.Beneficial effects of the present invention are as follows：1. not having the G tables module of entry by write-back to have the function that to remove G tables, the failure that can not be still accessed can be identified to solve hard disk by removing G tables；2. solve the problems, such as that it is slow that hard disk responds by the log information of deletion error.

Description

Western number hard disk can not access and run slow restorative procedure

Technical field

The invention belongs to data recovery field, and in particular to a kind of western number hard disk can not access and run slow reparation side Method.

Background technology

Hard disk the problem of various may occur using long, and hard disk " bad track " is most common among these asks Topic.There is bad track in addition to the reason for hard disk quality itself and aging in hard disk, mainly usually hard using can not above treat kindly Disk, for example internal memory is very little so that application software is to the frequent access of hard disk, it is unsuitable super to the undue continually defrag of hard disk Frequently, power quality is bad, and temperature is too high, dust-proof bad, vibrations etc..

The more or less presence bad track of each new hard disk for just having dispatched from the factory, only they P tables and G are hidden in by producer In table, with general softward interview less than it.G tables, also known as user class list, can about deposit hundreds of to 1,000 or so it is bad Road；P tables, also known as factory level list, 4000 or so bad track or more can be deposited.When maintenance, it will usually use software pair Hard disk carries out bad track scanning, and it is typically not real overall bad track in the case of overall bad track to occur when scanning, but The failures such as firmware cause hard disk the situation of inaccessible occur.

In addition, in use, hard disk occurs that response speed is very slow, and when above mentioned problem is repaired, people Would generally select low lattice or the mode reset totally, this certain mode is also can not be successful, because hard disk has occurred The situation of inaccessible.

Explanation of nouns：

UBA (Unit Block Address, cell block addressing)；

LITTLE-ENDIAN (little-endian, low byte sequence), corresponding is BIG-ENDIAN (big syllable sequence, high word Save sequence).

The content of the invention

In view of the deficiencies of the prior art, the present invention provides a kind of western number hard disk can not access and run slow reparation side Method, it can effectively solve the problem that Xi Shuo hard disk firmwares area failure causes hard disk to be identified, but data can not be accessed or can The problem of accessed, but the velocity anomaly that accesses is slow.

To solve problem above, the technical solution adopted by the present invention is as follows：A kind of western number hard disk can not access and run slow Slow restorative procedure, comprises the following steps：

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

002 is repaired again for responding slow situation after step 001 reparation hard disk.

Preferably,

001 specific method is as follows：

101 obtain No. 34 modules of hard disk, and No. 34 modules are G table modules；

102 open G table modules, G tables module are reset, and former check code is revised as into new check code；

103 are written back to the G table modules after modification on hard disk.

Preferably,

101 specific methods are as follows：

1011 read G table modules, read and successfully go to end, otherwise go to 1012；

1012 find a model and firmware version number all with faulty disk identical accessory tray；

1013 read the G table modules of accessory tray.

Preferably,

102 specific methods are as follows：

1021 open G table modules, navigate at offset address 0x06, and 2 words are taken out according to LITTLE-ENDIAN method Section, this value is the address that G table module contents starts；

1022 address since G table module contents is reset to segment data whole is terminated；

1023 four bytes since the 0x0C addresses of G table modules are the check code of G table modules, and new school is generated after clearing Code is tested, by the write-in of new check code herein.

Preferably,

002 specific method is as follows：

201 obtain No. 02 module of hard disk, and No. 02 module is parameter module；

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

203 are written back to the parameter module after modification on hard disk.

Preferably,

201 specific methods are as follows：

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

2012 find a model and firmware version number all with faulty disk identical accessory tray；

2013 read the parameter module of accessory tray.

Preferably,

202 specific methods are as follows：

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

2022 by zeros data of the parameter module from 0x4F4444 to 0x010028 in address field, but is free of two end values；

Four bytes that the 0x0C addresses of 2023 parameter modules start are the check code of parameter module, and new school is generated after clearing Code is tested, by the write-in of new check code herein.

Beneficial effects of the present invention are as follows：

1. there is no the G tables module of entry by write-back to have the function that to remove G tables, solves hard disk by removing G tables The failure that can be identified but can not be accessed；

2. solve the problems, such as that it is slow that hard disk responds by the log information of deletion error.
