One. Classification, symptoms, and detection methods of hard disk can be divided into hard faults and soft faults, non-biological faults, such as main boot records, partition, startup files, etc. Start, the hard disk is causing the virus infection that cannot be operated, as well as illegal operation, improper maintenance. This type of failure can generally be solved by software. The hard fault is physically fault, which is caused by the hard disk mechanical parts or the physical damage of electronic components. The hard disk that is common to handle is a bad track, and the most serious example is characterized by zero track damage. Other hardship barriers are basically exceeding our own ability to repair repairs. The classification and testing of the faults we said below and the maintenance of these do not exceed our own repairs. The general sign before the hard disk has problems if the hard disk fails, then it is best to discover and take the right measures as soon as possible. If you wait until the illness paste, the valuable data in the hard disk is unsaptable. In general, there will be the following performance before the hard disk is in the fault: S.m.a.r.t fault prompt. This is the automatic detection function built into the hard disk itself in the hard disk. This hint shows that your hard disk has a potential physical failure and will soon not regularly not run properly. Cancer when Windows is initialized. This situation is more complicated, first of all, other components should be excluded, such as memory quality is not good, the fan stop leads to overheating, or virus damage, etc. If it is determined to be a hard disk failure, then processes again. Can enter the Windows department ā system, but run the program error, while running the disk scan can also pass, often slowly stagnating at the time of scanning or even crazy. This phenomenon may be a hard disk problem, or it may be a short-term soft fault for Windows, and if it excludes the possibility of software settings, it is certain that the hard disk is physically fault. Can enter Windows, run the disk scanner directly to find errors or even bad, this doesn't have to say more, Windows's inspector reports in detail. The hard disk is suddenly unrecognized in the BIOS, or even if it can be identified, it is the most serious failure. It is said that there are so many signs that may happen, it is a feeling of being faint. In the following, we will break all the faults described above into four categories, respectively, summarize the symptoms of the four categories, summarize the method. When you determine the type of your fault, you can continue to see the second part of our topic "Failed Countermeasures" after you have summed it out. First we should confirm that the power interface of the hard disk and the data line do not fall off, then enter the BIOS, use "HDD Auto Detect" to detect the hard disk. If BIOS can correctly identify the hard disk correctly, then at least your hard disk has the hope of treatment; otherwise, I don't want everyone to be busy, because the tools of our ordinary DiYer are basically unable to force. 1) The main guidance zone fault is damaged due to the damage or operation of the virus, and the hard disk will not be able to start. After booting the system prompts "DiskbootFailure, InsertysystemDiskandPressenter" tells you that you can't find the startup partition hard disk or no boot file on your hard disk, please insert the boot disk and press the "Enter" button. If the hard disk in the BIOS is correct, you can find your hard drive after starting from a floppy or disc, then your machine is just because Windows startup files or hard drives are destroyed. The main guiding sector of the hard disk is the most sensitive part of the hard disk, where the main boot program is used to detect the correctness of the hard disk partition and determine the activity partition, which is responsible for handing the guiding power to the DOS or other operating system of the active partition. Segment procedures are damaged will not be guided from hard drives. 2) The hard disk is locked by "logical lock" is a very common prank.
After the logical lock, no matter what equipment is used, it is not necessary to boot the system. Even the floppy disk, the optical drive, and the dual hard drive are the same. If your hard disk has the above symptom, it is quite large. " Logic lock. "Logic Lock" Lock Principle: Computer will search all the order of all logical trays when booting the DOS system. When DOS is booted, first go to the partition table information of the main boot sector, then find the logic of the extension partition plate. "Logic Lock" modified normal primary boot partition record, pointing the first logical disk of the extension partition to yourself, so that DOS looks for the first logical disk while starting, find yourself, so A dead cycle is formed. 3) The partition table is damaged by the partitioned table error is one of the most serious errors of the hard disk, and the damage of the partition table data will cause confusion or loss of the partition. After booting the system with a disc or a floppy disk, you can try to enter the C drive. If you can't find the C drive, you should be a partitioned table error. This situation is likely to be damaged by hard disk partition table information, or attacked by a virus. 4) The symptoms showing the bad tracks appear as follows: Reading a file or running a certain software, it is often errors, or it needs to be operated for a long time to operate, and the hard disk is constantly reading the disk and issues a harsh noise. The phenomenon means that some sectors containing data on the hard disk are bad. When booting, the system cannot be guided by hard disk. After the flopp is started, it can be turned to the hard disk drive, but it cannot be entered, and the transmission system cannot be successful with the SYS command. This situation is more serious because it is very likely that the hard disk boot sector has problems. It has frequent blue screens frequently when using a computer. If it is formatted to the hard disk, the system prompts "TRACK 0 BAD", then it means that the 0 track of the hard disk is corrupted. In fact, 0 track damage is also a bad way, but the key 0 tracks have bad deeds. Two. Fault repair countermeasure under the main boot area repair, partition table corruption repair, hard disk logic lock repair, resulting in a resolution method and countermeasure for the resolution of the bad track: 1) Main boot area repair repair this fault The simple method is to use high version of DOS's FDisk with parameter / MBR operation (ie, "FDISK / MBR" command), directly overwritten (rewritten) the main boot program (FDisk.exe contains a complete hard disk main boot program) Code area. Since the DOS era until the current Windows system, the main boot program of the hard disk has not changed, so you can fix a DOS boot disk launch system and run this program. There is still a very important part in the main guide sector of the hard disk, which is its last two bytes: 55AA, which is a valid flag of the sector. When starting from a hard disk, a floppy disk or an optical zone, these two bytes will be detected, and if there is, it is considered to have a hard disk, otherwise the hard disk will not be recognized. In addition, we can also use some specialized tools: ★ kV3000 ★ KV3000 has a very powerful main boot record and partition repair. After you can start with a floppy disk, perform KV3000, press the "F6" button, you can see if the hard disk that is no longer booted, ie, check whether the hard disk 0 surface 0 column 1 sector main boot information is normal. If the key code is not found here, the hard disk partition table key code "80", "55AA", the hard disk itself will not be booted, even if the floppy is booted, it cannot enter the hard disk.
At this time, you can press the page button "PGDN" or "PGUP" button, and look for the hidden sector of the hard disk. If there is, flash red "80" and "55AA" will appear in the table. A prompt to prompt you, and there will be a prompt, "f9 = savetacket = savetoside0cylinder0sector1 !!!". At this time, press the "F9" button to guide the original hard disk main guide in the table, cover ā to the hard disk 0 surface 0 column 1 sector, then the machine will reboot the hard disk, restore the hard disk The main boot record. ★ Fixmbr ★ fixmbr is a DOS application gadget, only 12KB, specifically used to restructive main guiding sectors. Run the fixmbr directly, it will check the MBR structure, if the system is not normal, the reminder will appear. If you answer "Yes", it will search the partition. After searching the corresponding partition, the system prompts whether to modify the MBR, answer "Yes", start automatically repair. If there is a crazy phenomenon, please do the anti-virus function in the BIOS. All existing hard drives will be searched in the default state and complete the above operations. If the result is not pair, you can restore the result to the original state after you can restart the result. Executive "fixmbr /?" Can get the help information of FixmbR is as follows: USAGE: fixmbr [driveno] [/ a] [/ d] [/ z] [/ h] DrivenoharddiskScope0-3, DefaultisAllDrive. (Refer to hard disk number, 0 means A hard disk) / AActiveDospartition. (Activate Basic DOS Partition) / PDisplayPartition. (Displays the structure of the DOS partition) / ddisplaymbr. (Show main boot record content) / zzerombr. (Master Boot Record) / hthisMessage. (This help) / hthismessage. Information) 2) Partition Table Damage Repair Partition Table error is one of the most serious errors of hard drives, and it is generally unable to perform manual recovery. The only way is to rewrite back by backing up partition table data, or from other same types and partition status Get partition table data on the same hard disk, otherwise the other data will be permanently lost, however these tools will help us minimize losses. ★ KV3000 ★ On the main menu of KV3000, press the "F10" key to quickly test the relevant parameters of the system, and the hard disk partition table is quickly tested. If the hard disk partition table is not normal, the KV3000 will save the bad partition table to the floppy disk. Defense, automatically rebuild the hard disk partition table, so that the hard disk will return to life. But if the hard disk has only one partition, and the file allocation table (FAT table), the file catalog table (root table) is seriously damaged, the data has not been. Then, even if the C drive partition table is restored, the data cannot be recovered. At this time, you need to cooperate with other hard drive repair tools to recover data. If the hard disk has a few partitions of D, E ..., in general, the KV3000 can retrieve the partition that is not broken, rebuild a new hard disk partition table, then use the DOS system floppy disk to boot the machine, You can enter several partitions behind the hard drive, and the data is exported, and the hard disk is re-partitioned, format it. ★ Diskgenius ★ Diskgenius, full Chinese classic hard disk partition table maintenance software (shown in Figure 1), using a pure Chinese graphical interface to support mouse operation.
As a hard disk partition management tool, it does not only establish partition, delete partition, activation partition, etc., but also has the advantages of other tools to match: providing more flexible partition operations, support partition parameters editing; provide powerful partition tables Reconstruction function, quickly repair damaged partition table; support fast formatting of the FAT / FAT32 partition; directly adjust the size of the FAT / FAT32 partition directly without damaging the data; automatic reconstruction of the destroyed hard disk main boot record; Operation, for simple partitioning action, only change the memory buffer before the storage, does not affect the hard disk partition table; you can view the hard disk arbitrary sector and save to files; you can hide the FAT / FAT32 and NTFS partitions; you can back up to include logical partitions Table and each partition guidance records all hard disk partition information in ā; provides a scanning hard disk bad area function, reporting corrupted cylinders. The most people of Diskgenius is that its hard disk partition table recovery feature is mainly used to re-establish the partition table when the hard disk partition table is destroyed. Go to the Tools menu, select "Rebuild Partition Table" for hard disk partition, then the system will give "automatic mode or interactive mode", in general, "automatic mode", and the interactive mode gives each partition found. Tips, by the user choose whether or not. As long as the hard drive is not formatted, it is generally possible to restore the partition table of the hard disk. After the repair is required, the save is required, and the system can be restarted. 3) The hard disk logic lock is repaired to the "logical lock" to unlock the method of "hot plug" hard disk power. That is, when the system starts, do not power the locked hard disk, and then give the hard disk "hot" on the power line after starting, so that the system can control the hard drive normally. This is a very dangerous way, in order to reduce the risk of danger, after touching "logical lock", everyone is best dealing with two relatively simple and safe ways. ★ UltraEdit ★ First prepare a labet, then use a binary editing tool (recommended UltraEdit) on other normal machines (recommended to remember the property before the modification of the file will be changed to normal), specifically It is search for the first "55AA" string in this file, and it can be changed to any other values later. Use this modified system floppy disk you can start with the locked hard drive. However, this time because the normal partition table of the hard disk has been destroyed, you can't use "fdisk" to delete and modify the partition, but you can use the method described above with respect to the partition table recovery. ★ DM ★ Because DM is the hard disk tool for the motherboard BIOS to identify the hard disk, even if the hard disk is set to "None" in the motherboard BIOS, the DM can also identify the hard disk and format the operation, so we can also use it. The DM software is unlocked to the hard drive. First copy the DM to a system disk, turn it on the lock hard drive, press the "DEL" button to enter the BIOS setting, set all the IDE interface to "none" and save it, then use the floppy start system, the system is You can start "with lock", because the system is equal to no hard disk at this time. After starting the DM, you will find that the DM can identify the hard disk and select the hard disk to format the partition. This method is simple and convenient, but there is a fatal disadvantage, that is, the data on the hard disk can't stay ^ _ ^. 4) Repair hard disk bad tracks are divided into logical bad tracks and physics bad tracks. The former is logical fault, usually caused by software operation or improper use, and can be used for software repair; the latter is a physical failure, Indicates that your hard disk track produces physical damage, can only be solved by changing or hiding hard disk sectors.
1. Repair of logical bad tracks For logical bad deeds, Windows self-contained "ScanDisk" is the easiest solution. If the hard disk has a bad road, we can run the "Disk Scanner" in a Windows system environment, which will perform full scan for the hard disk disk, and automatically correct the possible bad clusters. In addition to Scandisk, there are many excellent third-party repair tools, such as Norton Disk Doctor NDD (Norton Disk Doctor) and PCTools, etc. also repair hard drive logic badges. In addition, each hard disk manufacturer's specific DiskManager program for the factory hard disk series is more familiar with the circuit structure and curing procedures of the hard disk itself, and it is more likely to repair hard disk errors. Therefore, it is recommended that everyone will download a dedicated Disk Manager program for their own manufacturers, which is more convenient to fix your own hard drive. 2, the isolation of physics bad tracks for unpackable bad clusters or physical bad deeds that appear on the hard disk, we can use some disk software to divide it separate into a zone and hide, let the head no longer read it, this can be To a certain extent, your hard drive has extended service life. It is necessary to emphasize that when using a bad drive, you must always do a good job of data backup, because there is a bad track on the hard disk, more bad tracks will follow, let you face no depression The database wants to cry without tears. Fix this error easiest tool is FDISK comes with the Windows system. If the hard disk has physical bad tracks, we can estimate the rules that are roughly positioned by ScanDisk and NDD. The logical partition of the bad track is removed, and the remaining is a good disk without a bad track. This work can also be done with disk software such as PartitionMagic, DiskManager. Such as the PartitionMagic partition software, first select the hard disk partition, scan the disk with the "Check Errors" command in the "Operation" menu, calculate the location on the hard disk, then select "Advanced / Bad Seafon Repeat" under the "Operation" menu "After dividing the hard disk of the bad cluster into multiple districts, select" Advanced / Hidden Partition "to hide the partition where the bad cluster is located under the" Operation "menu. This also guarantees the normal use of the hard disk of the serious bad track, and exempts the system frequently read the bad track to expand the area of the bad track. It is necessary to pay special attention to the repaired hard drive, do not use the FDISK partition tool under DOS to redistribute it, so as to avoid the starting fan of the hard disk, and our heart is vacant. This time, it is not the famous tool software mentioned above, but a small guy called "bad disc partition fbdisk (fixed bad disk)", only 20KB. This is a tool software that can reassign a hard disk with a bad track. Its main function is to automatically restrict the hard disk of the bad track, and set the bad track to hide the partition, and the track is set to the available partition and divide the bad track to prevent it from further spreading. When bad waves in the hard disk is too dispersed, it will generate multiple dispersed available partitions accordingly, but limited to the partition rules can only set up 4 primary partitions. The program will automatically select the largest four partitions to be available, and others are hidden. The specific steps can be divided into four steps: 1, download the package, after downloading, you can use it directly to use it, you can see two files containing fbdisk.exe and readme.txt in its program directory. 2. Making the boot disk first make a Windows boot disk, then copy it to the FBDisk.exe main program file.
Figure 1 asks if the hard disk is scanned 3, use the production startup disk to start the computer in DOS to enter the DOS state, then run the main program fbdisk.exe, which will first display the parameters of the hard disk, and ask if you scan your hard drive "START SCAN HARD DISK? (Y / N)" (Figure 1), press the "Y" confirmation, the program starts scanning, and the progress and remaining time (Figure 2) are displayed. Figure 2 Scanning progress and remaining time scanning process When the hard disk has a bad track, the program will automatically display the position of the broken track in the location for reference. After the hard disk scan is complete, the program will give a partition opinion and program while inquiring if it is written to the hard disk "Write to Disk? (Y / N)" (as shown in Figure 3). Note that the program has not written to the hard disk to any data. At this time, you only need to press the "Y" button, it will write the above partitioning scheme to the hard disk. As shown in the "Write Disk OK!", The write is successful. Figure 3 is inquiry if the hard disk is written here, using the "bad disc partitioner fbdisk" to the re-relocating work made by the bad hard disk is completed. 4. Formatting the hard disk Use this boot disk to start the computer again, then you can format the hard drive using the "format" command or other tool software comes with Windows. The next reload operating system, etc. "live", is of course simple ... 3, zero track damage repair during hard disk, when discovers zero track damage, in general, the hard disk is sentenced to death, very It is difficult to repair. However, for the case of damage to the hard disk 0 sector, although it is more tricky, it is not a good help. Reasonably use some disk software, block the damaged 0 sector, and use the 1 sector to take the possibility of "dead return", such software has PCTools and Norton Nu, etc. Enter the NU 8.0 toolkit directory, run its main program Norton.exe, then select "Disk Editor Diskedit", successfully run "Object Object", select "Partition Table" and place the starting sector of the hard disk from 0 The column 1 sector is changed to 0 surface 1 column 1 sector. It is also necessary to say that the change value must be determined according to the specific situation. After the last store, exit the restart computer, and format the hard drive in the format command. 4) Pressure axis package This is some free multi-function hard drive tools we collected for everyone, but the function is not large but the function is much, it is worth recommending. Let's introduce it to you: Sanhao hard disk doctor ★ Sanyi hard disk doctor is a full-free Chinese domestic hard disk repair tool, only more than a dozen KB, support non-standard hard disk parameters, than Diskgenius as shown in Figure 1 The description is the main interface of the three hard disk, where: "Analysis Hard Disk" helps you analyze if the system area of the hard disk is correct, and displays the results of the analysis; "Repair Hard Disk" helps you repair the unclear part of the hard disk system area; "Toolbox "To provide you with some practical gadgets, such as backups, system guidance zones, restore main bootes, etc .;" instructions "gives you detailed use of this software. Basically, the hard disk failure of our ability is here, if there is any "HDD Auto Detect" in the BIOS, the hard disk does not detect the hard disk, basically, pay attention to our related after-sales service. I hope that your hard drive is still in the warranty period. two. Fault repair countermeasure
Based on the main guiding area repair, partition table damage repair, hard disk logic lock repair, resulting in four fault types of bad tracks to list solutions to everyone: 1) Main guidance area repair
Fixing the simplest method of this failure is to use high version of the FDisk with parameter / MBR to run (ie, "fdisk / MBR" command), directly overwritten (rewritten) the main boot program (FDISK.exe is full The code area of the hard disk main bootstrap. Since the DOS era until the current Windows system, the main boot program of the hard disk has not changed, so you can fix a DOS boot disk launch system and run this program. There is still a very important part in the main guide sector of the hard disk, which is its last two bytes: 55AA, which is a valid flag of the sector. When starting from a hard disk, a floppy disk or an optical zone, these two bytes will be detected, and if there is, it is considered to have a hard disk, otherwise the hard disk will not be recognized.

At this time, you can press the page button "PGDN" or "PGUP" button, and look for the hidden sector of the hard disk. If there is, flash red "80" and "55AA" will appear in the table. A prompt to prompt you, and there will be a prompt, "f9 = savetacket = savetoside0cylinder0sector1 !!!". At this time, press the "F9" button to guide the original hard disk main guide in the table, cover ā to the hard disk 0 surface 0 column 1 sector, then the machine will reboot the hard disk, restore the hard disk The main boot record. ★ Fixmbr ★ fixmbr is a DOS application gadget, only 12KB, specifically used to restructive main guiding sectors. Run the fixmbr directly, it will check the MBR structure, if the system is not normal, the reminder will appear. If you answer "Yes", it will search the partition.

If there is a crazy phenomenon, please do the anti-virus function in the BIOS. All existing hard drives will be searched in the default state and complete the above operations. If the result is not pair, you can restore the result to the original state after you can restart the result. Executive "fixmbr /?" Can get the help information of FixmbR is as follows: USAGE: fixmbr [driveno] [/ a] [/ d] [/ z] [/ h] DrivenoharddiskScope0-3, DefaultisAllDrive.

2) Partition table damage repair
Partitioned error is one of the most difficult mistakes of hard drives, and it is generally unable to perform manual recovery. The only way is to rewrite back by backup partition table data, or obtain partition table data from other hard drives in the same type and partition status. Otherwise, other data will be permanently lost, but the following tools will help us minimize losses. ★ KV3000 ★ On the main menu of KV3000, press the "F10" key to quickly test the relevant parameters of the system, and the hard disk partition table is quickly tested. If the hard disk partition table is not normal, the KV3000 will save the bad partition table to the floppy disk.

Tips, by the user choose whether or not. As long as the hard drive is not formatted, it is generally possible to restore the partition table of the hard disk. After the repair is required, the save is required, and the system can be restarted.
3) Hard disk logic lock repair
The method for unlocking "logical lock" is "hot plug" hard disk power supply. That is, when the system starts, do not power the locked hard disk, and then give the hard disk "hot" on the power line after starting, so that the system can control the hard drive normally.

This method is simple and convenient, but there is a fatal disadvantage, that is, the data on the hard disk can't stay ^ _ ^.
4) Generate a repair of bad tracks
The hard disk bad deed is divided into logical bad tracks and physical bad tracks. The former is a logic fault, usually caused by software operation or improper use, can be used in software repair; the latter is a physical failure, indicating that your hard disk is generated. Physical damage can only be solved by changing or hiding hard disk sectors. 1, repair of logical bad tracks
For logical bad travelers, Windows comes with "ScanDisk" is the easiest solution.

1, download the package, directly decompressed directly after downloading, you can see two files containing fbdisk.exe and readme.txt in its program directory. 2. Making the boot disk first make a Windows boot disk, then copy it to the FBDisk.exe main program file.
Figure 1 Ask if the hard disk is scanned
3, use the Making start disk to start the computer in DOS Enter the DOS state, then run the main program fbdisk.exe, which will first display the parameters of the hard disk and ask you to scan the hard disk "Start Scan Hard Disk." / N) "(Figure 1), press the" Y "key to confirm, the program starts scanning, and the progress and remaining time (as shown in Figure 2).
Figure 2 Scanning progress and remaining time
During the scanning process, if the hard disk has a bad track, the program will automatically display the location of the broken track to be referenced. After the hard disk scan is complete, the program will give a partition opinion and program while inquiring if it is written to the hard disk "Write to Disk? (Y / N)" (as shown in Figure 3). Note that the program has not written to the hard disk to any data. At this time, you only need to press the "Y" button, it will write the above partitioning scheme to the hard disk. As shown in the "Write Disk OK!", The write is successful.
Figure 3 Ask if you write a hard disk
At this point, the repartition of the bad hard drive is completed using the "bad disc partitioner fbdisk".
4. Formatting the hard disk Use this boot disk to start the computer again, then you can format the hard drive using the "format" command or other tool software comes with Windows. The next reloading operating system, "live children", of course, more simple ... 3, zero track damage repair
During the hard disk use, when zero track is found, the hard disk is sentenced to the death penalty, it is difficult to repair. However, for the case of damage to the hard disk 0 sector, although it is more tricky, it is not a good help. Reasonably use some disk software, block the damaged 0 sector, and use the 1 sector to take the possibility of "dead return", such software has PCTools and Norton Nu, etc.
Enter the NU 8.0 toolkit directory, run its main program Norton.exe, then select "Disk Editor Diskedit", successfully run "Object Object", select "Partition Table" and place the starting sector of the hard disk from 0 The column 1 sector is changed to 0 face 1 column 1 sector. It is also necessary to say that the change value must be determined according to the specific situation. After the last store, exit the restart computer, and format the hard drive in the format command.
4) Pressure axis package
