希捷硬盘修复进阶指南（Seagate hard disk repair Advanced Guide）

"In the article, we introduced the processing method when the

hard disk when the fault occurred, we believe that in after

reading on how to repair the hard disk of a certain

understanding. However, previous articles only gave you an

outline of thinking and judgment, and in the process of hard

disk repair, you must also master some other tools and

techniques to complete the work smoothly. For example, when you

got a faulty Seagate hard disk, what would you do to get it?

/ /

Seagate hard disk has a considerable amount of possession in

Chinese game player, but on its maintenance (including bad

sectors, and other aspects of the firmware) is perplexed by the

user. In the following, the author, based on his personal

experience of Seagate hard disk maintenance, will show you how

to save your strike hard disk with the proper steps and the

proper hardware and software tools.

A damage detection -- for repairs before

When the hard disk failure, first do not panic with hands, it

should be the first to use bad detection software check familiar

about the number of bad sectors and bad position, I strongly

recommend "efficient source of large capacity hard disk

detection and repair program", the tool is more intuitive, with

Chinese language habits.

After detecting the end if the large number of bad sectors, bad

sectors (generally 3000 to the bottom line), the first not to

rush in with software entries to defect list (P-List and

G-List).

Table //G-List: growth defect list, the utility model has the

advantages of fast repair bad sectors and retain data, is the

number of bad sectors can be added to the disadvantages of too

little, some of the old hard disk only hundreds of P-List;

P-List: the factory is a list of defects, the number of entries

to the advantage, how many have a relationship with the capacity

of hard disk size. The disadvantage is that after adding, the

data is lost, and some hard disk after the completion of the

P table needs to be cleared before it can take effect, such as

Fujitsu and Seagate most of the hard disk is like this.

/ /

If after we detect bad sectors directly into the join list of

defects, it is very easy to cause the G table overflow, before

I repaired many Meizuan old hard disk has such defects; secondly,

to false bad sectors also added in, but the real sectors

remained, cannot be added. So before repair, we should use DM

and MHDD software to the hard disk reset once (I recommend using

Erase erase function in MHDD), can repair a large number of

logical defects, the remaining small part of the bad sectors,

and then added to the list of defects, can well solve the problem

of bad sectors.

Sometimes you will find some use in the disc may be more wiping

more bad sectors, for example, ST and WD, is estimated to disk

instability caused by aging, in the repair process should be

paid attention to. Appropriate tools and repair techniques are

important. The following author to "efficiency source Seagate

hard disk repair tool" as an example, actually see how to repair

a seemingly scrapped hard disk.

/ / Note: the following operation involves many professional

knowledge and practical skills, suggested that the relevant

operations are not familiar with the hard drive in under the

guidance of experienced game player. / /

Two, actual combat efficiency source - hard drive back to life

1. efficiency source Seagate hard disk repair tool profile

Seagate firmware program mainly for repair bad sectors and

physical bad sectors are unable to identify the motherboard

hard disk, can be repaired for some abnormal sound of the hard

disk. In case of data recovery or hard disk drive, the disk will

be restored to normal only in a flash, and the original hard

disk data will be retained as well. This procedure to repair

the physical bad sectors are fast, G-LIST writing can reach 3

per second, P-LIST added up to 2 per second, G-LIST to P-LIST

can be completed within 30 seconds and the hard disk read and

write firmware required time is only 30 seconds, remove hard

disk password for about 1 seconds. According to the head caused

problems with compliance rate of bad sectors can also directly

to the head position of physical shielding. The whole firmware

can be checked, and the specific error module can be found and

re written, which is suitable for all kinds of hard disk

maintenance professionals and high-level DIY enthusiasts to

use. I personally have been for it is currently for Seagate hard

disk repair, the most powerful, the most efficient software.

2. efficiency source repair hard disk skills talk about

According to the hard disk maintenance experience, I suggest

that you first make a full reset (by DM, MHDD, Erase function

will do) it can eliminate the hard disk ECC&CRC error (that is

we often say that the logical bad sectors). Then the efficiency

of the source Seagate hard drive repair tool will be added after

the bad sectors G-LIST, G-LIST to P-LIST, and finally to do a

hard disk reset (with format can be achieved).

Trouble hard disk clear

In accordance with the above steps, first use the familiar MHDD

to clear the whole. MHDD is a free hard disk entity scanner

maintenance program developed by the Russians. Its cleared

function can be used by the ERASE command line. Erase can set

the start and end values of the clearing so that the ECC and

CRC errors at the specified location are cleared. Very

convenient！ Unfortunately, there was an error in the middle

of the execution, and the reset operation was interrupted.

Figure 2:MHDD reset failed /

Try to use DM to provide clear function, but also break out,

and to repair the hard disk model don't recognize, had no choice

but to use the hot swap method to bypass the BIOS to start the

self check, access the hard drive into the efficiency of the

source Seagate firmware maintenance procedures to repair bad

sectors.

Figure 3: the same failure / / DM reset

Figure 4: the utilization efficiency of the source / firmware

maintenance

First, detect firmware. When the hard disk status window shows

"REDAY", click "CK FW", and the program reads all the firmware

from the hard disk to memory, compares it with the standard

firmware, and gives the comparison results in the information

window. Like the author after using DM to cause the hard disk

to search the normal, but do not recognize the disk phenomenon,

you can use CKFW to detect the bad module, and write with a good

module.

Figure 5: / / detect the hard disk firmware

The program reads all the modules from the firmware area and

performs regular tests. When you have finished, you will

display the details on the left side of the interface. You can

use the mouse to flip to see the verification status. The

correct check will show that the check result is OK! The error

will be displayed as ERR!.

Figure 6: / / calibration results

The efficiency of the source Seagate firmware repair procedure

added damage automatic repair function from the 2.1 version,

if the firmware module detected a problem, the program will show

"".

At this point, click "Yes" will automatically repair the

firmware, repair, continue to check, click "NO", ignore,

continue to check, it is recommended after the repair test again

to confirm the repair results.

Figure 7: / / repair after the best testing again

After the automatic repair module, you can easily recognize the

disk. Next, you can use the maintenance tool to perform the

clearing.

writing of defect tables

From the previous article we know that in G-List scanning and

form, can be directly effective without clear operation of the

hard disk; and by means of P-LIST scanning and table, to cut

off once, and then do a reset on the hard disk, P-List can take

effect. So I suggest you first add G-List, and then do

G-List->P-List conversion, and finally cleared together, so

that you can save time.

First, use the efficiency source Seagate tools to scan and add

tables in G-List mode. After you start typing LBA, end LBA, and

time parameters, click GL, the program will start scanning the

bad sectors of the hard disk, and then the bad sectors will be

added to the G table after the scan is complete. Press F5, not

join G-List and exit, press F7 to join G-List and exit.

Figure 8: / / scan with G-List and repair defects

After the GL scan is completed, the GL turns to the PL table.

When the hard disk status window displays REDAY, click "GLtoPL",

the program will transfer all G-List to P-List, and empty

G-List.

Finally, LFORMAT (price) to do a clear operation, thus the

maintenance basically ended. After the repair using the PQ

partition is exceptionally smooth, repair bad sectors ended.

Three, after the maintenance

Software is dead, people are alive, only the correct grasp of

the use of software, and then according to the specific reasons

for the damage of the hard disk flexible handling, in order to

achieve the best repair success rate. Practice has proved that

the repair disk to a variety of tools, combined with the use

of, in order to achieve the best results, there is no tool is

omnipotent.

Due to the different manufacturers and products, the

corresponding maintenance software and maintenance processes

are not the same. At the same time, for business reasons, the

hard disk manufacturers and maintenance software manufacturers

to form a relationship between spear and shield, all of which

invisibly make the repair disk to become a technical activity,

while constantly testing your patience. Only diligently

efforts, can we understand the essentials of hard disk repair.

Only by adhering to the meticulous, serious and professional

spirit can the repair work be carried out to the end. Although

it involves hard fault surface repair mainly by professional

maintenance personnel to complete, but with excellent tools

such as the source of the efficiency of popularity, who can say

that DIYer can not repair the master disc door juehuoer?
