If a problem occurs in the data area of the original, because the data itself is corrupted, the file's information is accurate and without error contents of the file corrupted or overlaid in the form can not expect normal recovery rate.
Data corruption occurs to find the old data that is received as a backup system to recover or locate the file can increase the recovery rate.
Two. File index corruption (File Error)]
File Table (FAT, MFT) damage, injury by the data area can not be read files is a problem. Distributed data to a file stored in the continuity of the relationship can not find the data recovery rate is less difficult to recover.
Regular backups and Disk Defragmenter in advance through the file index corruption problem can be prevented.
Three. [File corruption problem Recover
File corruption when the file name, capacity, time, etc. system (Explorer, DOS windows, etc.) On a present, but the file does not open, or, if yeolrideo the original file can not verify the contents of this issue is caused by the following causes.
- Viruses, corrupted files, save the file itself, by error, etc.
- The location of the data area of the data values do not match gaphago not open
- Storage devices (HDD, USB Memory ..) is in poor condition because of a particular area is not read
The symptoms appear similar, but the exact cause of symptoms and diagnosis as a variety of needs.
Four. [File system damage (File System Damage - MBR, BOOT error)]
Drive recognition region (MBR, Boot) is damaged storage devices are viruses that do not understand, the program causes problems such as conflicts.
Computer (storage device) when using an unknown character filenames seem to stop immediately if you use a computer consulting experts and shall continue to the computer (storage device), or Nmap, when the program decreases the recovery rate of the stored data.
5 [E-mail (E-mail) Repair
MS Outlook, Outlook Express when using the delete mail yeotgeona, and many other symptoms due to the mail data is corrupted and unable to view mail problems, the main cause of the injury as follows:
- MS Outlook, Outlook Express, etc. If you delete mail from your mail client program
- Damage to the mail file (*. PST, *. DBX) If you do not open e-mail to
- Format and reinstall Windows, the virus disappears or is damaged due to the mail data
- Storage of the physical damage (bad sector ..) If the mail data is missing or damaged
* E-mail notes and corruption prevention measures when using
- Webmail (Hanmail, empal, naver ..) Empty Inbox, a user when deleting or personal information left on your PC, so do not be recovered, and keep important mail is stored on the PC.
- MS Outlook (*. PST) / Outlook Express (*. DBX) when using the important e-mail data for each of the folders created to manage and regular backup files with the size of a given size, (2 G) under management and file corruption case is.
6. Password (password) and the problems caused by lost files, and system access issues]
Instrument or system to protect critical Server, PC, laptop, documents, and set the password, neglect, or operational errors, hacking, virus problems such as corrupt and do not have access to data or systems is a problem.
To recover the password in any way (physical, software eojeok, pro geuraemsang per-file basis) whether the password is set to be pinpointing for quick recovery is possible.
7 [File corruption caused by a virus / loss issues]
Internet, network, and removable storage devices, the computer virus that is spread by poor performance, and system down the problem and at the same time raises the following issues.
- Data corruption / loss
- The deletion of folders and files
- Can not access storage device
- Hardware failure.
In this case, the recovery rate of the virus type and the two will vary depending on the cause, if any of these symptoms occur, contact a professional to turn off the power should prevent additional damage.
Malicious viruses typical form, CIH, Worm, Trojan horses and viruses in the form, along with regular security patches, virus and spam checks, or does not have a certificate file that you do not install is the best prevention.
If severe symptoms should be conducted with an agent sangdamhu
* The main symptom of system failure due to viruses
- Abnormal behavior when running certain programs, freeze, if the system will be down
- Destruction of the file system (file deletion) and inaccessible storage devices
- BIOS, hard disk, and if you can not boot Windows
- Strange characters or pictures on the screen, if scattered
- If data is deleted indiscriminately
Eight. [Data structure corruption caused by viruses]
Infection alters the value of the data area from the OS disables the use of data and at the same time raises the following issues.
- The operating system unbootable
- When connecting other computer storage device not recognized
- An unknown area display
Other storage device connected to a PC if the treatment and recovery of vaccine virus through a PC with transition issues should be blocked, the virus recovery after treatment should be conducted by the virus can prevent additional problems.
Nine. [Deleted due to virus / Overwrite]
Infection with certain viruses that overwrite or delete files due to a series of MS Office files or Jpg, Gif, Bmp, and image files usually have been harmed.
If the data is essentially a compromise so much a deep infection, the data recovery rate drops significantly. Immediately found a problem on your PC, disconnect the power and consult with experts on the virus, treatment and recovery should proceed.
10 [Empty Recycle Bin (delete) a data recovery]
When you delete a file or folder is stored in the Recycle Bin on Windows to provide data through the Empty Trash to delete and after the final through Explorer will not be able to find the data. The value of a region of a file is deleted from the storage device is marked for deletion of data that is recognized but not completely delete the data.
Continuously using a PC or installing programs, file copy, NDD, SCANDISK, and if the recovery rate used to diminish, there is a problem right away, or commercial use, contact a professional data recovery tools, data corruption issue additional best practice to minimize is the way.
* Note: OS is an operation of the storage device if you want to recover files stored on another PC by connecting the device to be data recovery data recovery rate can increase.
11 [Format (Format) a storage device, data recovery]
Format a storage device was unlike the data storage device, clear the whole is perceived as empty space.
Format after installing programs, file copy, NDD, SCANDISK, and work if you do not unformat command or general commercial data recovery programs through the most able to recover an additional action case of its extent depending on the data recovery rate two natahjimeu problems with Ask the Expert in the event of any additional data to minimize the corruption problem is the best solution.
12 [Low-level format (Low Level Format) a storage device, data recovery]
Low Level Format to format the physical drives, unlike the general format of the data in all areas will be deleted.
The physical unit of storage in the sector by examining all areas by deleting time consuming and if the command has finished executing a data recovery is not possible, during the recovery of remaining data in case of interruption is possible.
Low Level Format mistake if you were running when the problem occurred immediately and contact a professional to minimize any additional data corruption problems that are the most effective way.
13. [Operating System (OS), reinstall the storage of data recovery]
Operating system (OS) installed on the hard disk, the data in order, but rather arbitrarily because it is stored in an empty area of the existing data, such as the newly installed operating system or program files are overwritten, depending on how much recovery rate is different.
Area of the existing data can be recovered if the value is alive and if a problem occurs, contact a professional to minimize any additional data corruption problems that are the most effective way.
14. [When using the restore CD or a ghost program]
Supported PC purchase program allows you to restore a CD or a ghost at the time of purchase to the time or place to burn the image is restored.
When restoring data to the hard disk in order, but rather arbitrarily because it is stored in an empty area of the existing data, such as the newly installed OS or program files are overwritten, depending on how two recovery rate may be different.
Operating system (OS), just as you reinstall the area of the existing data can be recovered if the value is alive and if a problem occurs, contact a professional to minimize any additional data corruption problems that are the most effective way to
* If jaeseolchiman without further action by the relatively high recovery rate
15. [Partition settings (FDISK) issue]
Fdisk is a new set of hard disk partition information is divided into multiple drives, or is used to combine the information and the runtime data area (MBR, BOOT, FAT, ROOT directory), the data set as new information goes with all the existing information .
User error, viruses, programmed by the collision the partition information has been deleted the HDD are initialized in the form of recognition impossible even further corruption, unless most of the files to undo recovery is possible, so if a problem occurs, contact a professional and additional data corruption is the most effective way to minimize.
Continuously using a PC or installing programs, file copy, NDD, SCANDISK, and if you used two natahjimeu recovery rate, the damage occurs immediately, or commercial recovery program should consult with experts.
16. System Restore (Windows XP support)]
Changes that may harm your system by using System Restore to clear the settings and performance of the system with the ability to restore documents, files, e-mail, web browsing history, favorites, including a list of recent work on an earlier point in time without compromising information (called a restore point) is a program to return to the system.
Means for the data, rather than restore or repair parts for the system as a means to remove data that you restore your system does not recover any data.
17. [Norton (Norton Ndd) through the data restore]
Norton Ndd data backup, restore, data recovery program helps. Data corruption / loss, there is a problem not pinpoint the cause of symptoms, the situation is dangerous to run the program from the available file recovery is likely to be damaged too.
Ndd correctly configure the OS part of the structural recovery is possible only when there is a living, and asks me to write an executable part, even if progress is not recommended anymore.
* Unconfirmed data will be overwritten, it can not be recovered may be capped
18. [Check Disk (CHKDSK)]
CHKDSK on the disk, and creates and displays a status report shows errors on the disk that provides the ability to modify the services provided by the OS by default (instruction) is
CHKDSK is usual on a regular basis to manage data storage devices, as well as the reliability of the data can also improve the data recovery rate.
However, data loss / corruption to run after dropping significantly, the data recovery rate should not be executed.
19. [Boot recorder ((Boot Record) corruption]
Disk operating system installed on a computer system that stores the instructions for goteumyeo, when you boot the computer read the first record is called the boot sector, this sector. Boot Record is damaged [Missing operating system] is the output message does not go looking to boot.
Boot problem caused by a virus that causes damage to the recorder or physically bad sector occurs in that part can be separated into the problem of the problem occurs because the additional contact a professional to minimize data corruption issue is the most effective way.
20 [Master boot recorder (MBR, Master Boot Record) corruption]
Recorded at the beginning of the hard disk on your computer system start-zone when power is recorded in the MBR of the hard disk ilhimyeonseo OS startup programs written portion of the program (boot sector) required to run the operating system to read is a part.
The MBR is corrupted [Invalid operating system] is the output message is not made bootable.
In this case, the problem caused by a virus or bad sector on the part physically occurs and can be separated into the problem of specialists to contact if a problem occurs because the additional data corruption issue is the most effective way to minimize.
21. [File allocation area (FAT, File Allocation Table) damage]
Files (data) is stored to provide the location of clusters in the FAT area allocation tables get corrupted when the following occurs and the data can not be read.
- Symptoms of the data is lost or broken
- Can not boot from hard disk
- Directory, the file can not copy (Sector not found 'message is output)
- File reading, the program can not run
In this case, the problem caused by a virus or bad sector on the part physically occurs and can be separated into the problem of specialists to contact if a problem occurs because the additional data corruption issue is the most effective way to minimize.
22. [Root directory (Root Directory) damage]
File in the directory structure of the system to the directory where the starting point of the top in this area when damaged can not see the folder structure itself, the main symptoms are as follows:
- Hard disk can not boot
- When accessing the folder 'file not found' message is output
The cause of most virus or physically bad sector occurs in the root directory can be divided into the problem of the problem occurs, contact a professional to minimize any additional data corruption problem that is the best solution.
23. [Hard disk crash, and an external shock]
Internal hard disks are very sensitive to physical shock or electric spindle motor, heads, platters, etc., or because it has a hard disk crash, if an external shock is applied to damage the hard disk is unusable.
The main symptoms include head injury, the spindle motor damage, noise, due to damage to the platter storage devices not recognized or even recognition boot / will not be able to do normal work.
If the power supply continues to operate the larger secondary Estimated damage doemeuro unplug it immediately and contact a professional to minimize any additional data corruption problems that are the most effective way.
24. [Hard disk, flood damage]
Electricity is supplied to operate the equipment as well as most of the hard disks are vulnerable to water or moisture.
If a hard disk was exposed to water contaminants (water or other substances) into the hard disk spindle motor of the hard disk when the power supply, PCB boards, platters, heads, etc. can severely damage the power supply should not be absolute .
Go inside even after all moisture has been removed stuck debris can cause serious problems during operation, so if you problems as it is flooded soon as possible contact a professional to minimize any additional data corruption problems that are the most effective way.
25. [Hard disk, fire damage]
If a fire occurs around the first of the hard disk is damaged cable or PCB board, if a temperature rise above the platter as the magnetic material damage may be impossible to repair itself.
By shocks in the process of fire extinguishing water and stored in multiple types of devices that can cause problems depending on the problem, contact a professional in the state as soon as possible to minimize additional data corruption problems that are the most effective way.
26. [Full-disk bad sector (Bad Sector) issue]
Bad Sector can write data to a storage area in the manufacturing process does not produce but also occurs during most of the use of computers.
All Bad Sector occurs when the hard disk is recognized, but the contents can not see any hard disk in the sectors of the bed sector recognition and the major potential causes of head injury, the data area of the track and the head position changes caused by is.
First, the damaged parts, repair / replacement must be due to the dust and debris in order to solve the problem for working facilities (clean rooms, clean benches) where two experts appointed by the operation must be carried out.
27. [Disk bad sector part (Bad Sector)]
Due to the bad sector problem symptoms and physical symptoms due to logical problems, there are two types.
* Physical symptoms
- HDD disk surface damage
- Long-term use, if weakened by the magnetic properties
- Due to external shocks
* Logical symptoms
- Operating system or software required by eojeok to prevent writing data into the sector in the form of bed if you specify in advance
Even if the low physical format and logical bad sector remain low if the problem can erase bad sector format.
The part that looks like a bad sector data recovery when data can not read data is impossible to view the contents of the MBR, Boot If there is bad sector in areas such as recognition of the hard disk becomes impossible.
Bad sector occurs when used continuously, even after a bad sector on your hard disk, increasing the damage by giving to the other data around fast action in this case will have an important impact on the recovery rate.
28. [Scratch the disk platter (Disk Flatter Scratch) damage]
Damage to the hard disk platters in a high-speed rotation, I phenomenon Manipulator won because most occur in the form of a scratching noises and manipulators, so symptoms should immediately disconnect power loss of stored data can be minimized.
If you experience a normal part of the scratch is difficult to read, in order to recover enough so you need to know and work with sufficient confidence to be secured by an expert data recovery and data loss can be minimized.
Damaged parts repair / replacement must be due to the dust and debris in order to solve the problem for working facilities (clean rooms, clean benches) where two experts appointed by the operation must be carried out.
29. [Storage Device not recognized (Hard Disk Fail)]
Disk Fail C-mos during boot the PC to recognize the hardware, but in the process of checking the 'Hard Disk Fail' display a message while booting was impossible, or if you have access storage devices Sub the problem is impossible.
Failure problem head and the platter, spindle motors, and more, and caused by bad sector, damaged parts before repair / replacement must solve the problems caused by dust and debris to a facility for operation (clean room, clean bench) is experts appointed by the place to be in the process.
30. [Hard disk heads hang (HDD Disk Head Stiction)]
Information on the platters of the hard disk read heads, is responsible for the ability to save. The head is fixed, we're unable to read the information on the HDD as a major cause of the problem are as follows:
- A sudden power-off phenomenon
- Head external and internal contamination due to the spindle motor is attached to the platter If you do not drive
- Spindle motor failure (similar phenomenon occurs)
First, the damaged parts, repair / replacement must be due to the dust and debris in order to solve the problem for working facilities (clean rooms, clean benches) where two experts appointed by the operation must be carried out.
31 [PCB substrate damage]
HDD PCB substrate electric shock, excessive heat generation due to the PCB board is damaged, data access becomes impossible to address the problem in the past, just the same HDD (manufacturer, capacity, match) if you have the PCB by replacing relatively easy data recovery Chip of the PCB can be, but recent work with the information should be able to read the information in the form of HDD common problems caused by PCB as data recovery is not quite that simple.
In addition, the case of electrical shock or excessive heat that affected not just the PCB is not only because there is a problem based on symptoms need careful data recovery plan.
32. [Spindle motor failure and malfunction.]
Platters spinning at high speed spindle motor, which acts as its own problems and defects due to failure of the PCB is without power or not the normal behavior of the storage device can not read the information can cause problems.
In particular, the constant speed is above the platter over the constant scooping action that should be operational malfunction or failure of the spindle head on the platter is damaged due to the potential problems may occur.
First, the damaged parts, repair / replacement must be due to the dust and debris in order to solve the problem for working facilities (clean rooms, clean benches) where two experts appointed by the operation must be carried out.
33. [Hard disk noise.]
Hard disk drive (HDD) spindle motor due to the constant noise PC operation occurs, but if an unusual noise problems caused by hard disk storage platform sonsangdeung serious damage that can happen as soon as disconnect the power and shall be referred to specialists.
- Unusually loud noise occurs when the hard disk drive and the quality
- Scratching noises when
- Repeatedly, like crackling noises when hitting
First, the damaged parts, repair / replacement must be due to the dust and debris in order to solve the problem for working facilities (clean rooms, clean benches) where two fully equipped operation must be carried out by experts
34 [FDD / removable storage devices, damage]
FDD external shocks and climate-sensitive storage devices are not widely used nowadays.
Most of the disk itself cause damage or bad sector on the disk as you use a major cause more severe damage will not be recognized.
When using the backup operation should occur in well-made conditions can reduce the damage and recovery program that has only the status of the disk should be careful not to get worse.
35. [CD / DVD data stored in the Recovery
CD / DVD scratches in use, heat, magnetic fields can not read data that is stored by the situation occurs.
CD / DVD RW Due to the prevalence of the many CD / DVD using a clear and direct as inside information, if you use a lot of that used with the hard disk drive (HDD) with a recovery rate can increase if you refer.
