How to Fix Corrupt Files Or Corrupted Data

If you could not open a file or send it to the Recycle Bin, there is the possibility that it is corrupted. There are many things that can cause a file to be corrupted; it could be the result of software failure, a virus infection, or a system crash. If you have just downloaded the file and it will not open or run, it could be that it was corrupted during the download. If the data transfer rate is too slow during download, there is a great possibility that the file will be flawed and would not open. Defects in the file system of the hard disk  or in the disk itself can also cause files to be corrupted. Corrupt files can cause you headaches but the good thing is that the probability of saving or fixing a corrupted file is quite high.

Because there are many things that can cause files to become defective, there are also many ways that can lead to the solution of a corrupt file problem that you can. You can restore corrupt or lost files from recent backup. Numerous programs automatically produce back up files; one good example is Microsoft Word, a widely used word processing program. It automatically backs up .doc files with .wbk files. If you somehow find that your Word document file is corrupted, try looking for the file in the same folder that has the extension .wbk and change it to .doc. You will then be able to open it using MS Word.

You can also use the System Restore tool if the problem is caused by accidental disk format or bad installation. Windows XP allows for the rollback of system files to previous states when the system was working properly. If your system fails to work normally after installing or uninstalling a software or an update, you can simply rollback to previous working states of your system.

How to Fix Corrupt Files Or Corrupted Data

If you want to fix lost or corrupted top-level folders that contain different kinds of file types, it would be best to use HDD Regenerator or Partition Recovery. If you are not really sure about the kinds of files in the folder to be fixed, you can make use of FAT Recovery or NTFS Recovery. You can also use some file recovery tools like Recover My Files (for recovering lost data), DOC Regenerator for fixing or rescuing Microsoft Word documents, XLS Regenerator (for fixing Microsoft Excel files). For partially downloaded .AVI files you may use DivFix. If the file that needs to be fixed is .ASF file, you can use AsfBin and AsfBinGUI, a free but powerful command line utility that can cut, join, and repair fragments of .asf files. There are hundreds of software out there that can recover or fix different kinds of files. Just Google terms like "Fix broken files" or "fix corrupt files" or any term that you think can lead you to the right software.

If all else fails to fix or recover your file, you have no choice but to pay for the services of people who are expert in data recovery. But before you do it, be sure to try all the solutions mentioned above.

How Data Is Stored On A Hard Drive

When a file is saved on a computer, the data is stored on the hard disk platter's magnetic coating. This magnetic coating on the platters is the 'glue' that keeps your data. Any damage to that magnetic coating means that there is data loss as each piece of missing coating contains data. So a platter missing a little bit of that coating has a better chance of a successful data recovery as opposed to a platter that has had massive amounts of that magnetic coating removed or destroyed.

Hard Drive Failure Parts

Typical hard disk components that fail include:

How Data Is Stored On A Hard Drive

Platters Hard disk platters, or spindle, is rotated by an electric motor. The speed of this rotation is measured in rotations per minute (RPM) and the higher the performance of the hard drive...the higher the RPM is which increases the reading and writing of data to the platters. Any surface contact to the platters can cause serious damage to the magnetic strip the contains the data. This includes dust, finger prints, water, and most important of all, the heads of the hard drive. Platter damage is the most serious type of damage to cause hard drive failure.

Heads (Head Crash) When the hard disk is not actively in use, the heads are parked until the hard drive needs to read or write data again. It is when this head moves outside the super thin cushion of air between platters that causes the head to crash and touches the hard disk platter.

Firmware Firmware is the program instructions located on the chips on the Printed Circuit Board (PCB). Each firmware revision is specific to its hard drive type and each hard drive can go through dozens of firmware revisions to increase that particular manufacturer's disk drive's performance. The older the hard drive, the more difficult it could be to find a working firmware for that specific hard disk model.

Printed Circuit Board (PCB) The PCB of the hard drive is the electronics of the hard disk that manages and operates the hard drive. If a PCB becomes damaged it is often replaced with an identical PCB with the same firmware on the original hard drive. Typically PCB damage is from water or fire, but there are other reasons why a PCB would fail. And many times a failed PCB affect other aspects like firmware or heads.

Types of Hard Drive Failure

Generally speaking, when a disk drive fails it is due to one of the following causes:

Media Failure Otherwise known as a head crash (as described above), the heads of the hard drive have physically touched and damaged the magnetic coating on the platters.

Mechanical Failure Generally speaking, any electronic failure to the hard drive falls in this category. Fire, water, electrical damage to the hard disk would require 'parts' replacement.

PCB Failure As described above, PCB failure falls in the mechanical failure type and typically can be 'swapped out' for an identical PCB for that specific hard drive type. Along with the correct firmware for that disk drive, a PCB replacement can be a difficult type of hard drive repair if the hard drive is an older model.

Logical Drive Failure This type of hard drive failure is usually the least damaging to the data. This type of error usually means that the operating system of the computer (or utilities) can see the drive, has marked it as unallocated space, but because the computer's MFT is corrupted or damaged, can't read the data. Hard drive failure of this type is not that destructive and the chances of a complete successful data recovery are high.

Types of Non-Mechanical Hard Drive Failure

Other causes for data loss and why data recovery would be required could include the following:

Natural Disasters Extreme weather conditions that are out of our control can make a bad day even worse. Whether the computer was submerged in water due to a flood, scorched by fire or in the proximity of a lightning strike, there is still a chance to recover data from the hard drive.

The Human Factor Accidentally deleting files, formatting the wrong hard drive, and attempting to upgrade you operating system only to have it fail are common issues that come up. Also, as careful as most people are with their laptops, a small drop from the couch to the floor or down a flight of stairs, is the type of forceful jarring to the disk drive that could cause serious damage to the hard drive platters.

Viruses E-mail typically are the way most viruses are spread from computer to computer. Also, visiting questionable websites that have scripts, malware or spyware waiting to comprise your system and put your data at risk. It is recommended to run the most recent anti-virus software to protect your data from this sort of data loss and to reduce the need to require data recovery service.

So how do you protect yourself from losing your data? Back it up! However, should you still require data recovery services, be sure to use a company that specializes in hard drive data recovery.

'SMART - Status Bad - Backup and Replace' Hard Disk Error and Recovery

Physical hard disk failure refers to the condition in which data stored in the system becomes inaccessible due to hard disk malfunction. A hard disk is comprised of several mechanical and electronic components. But when these components get affected due to external factors like high intensity magnetic waves, sharp impact, temperature, water or fire, they get physically failed. Also, internal issues like wear and tear, low material quality and poor composition cause hard drive failure. In such cases, Hard Disk Recovery service can come to rescue and recover all lost data.

Hard drive failure is not instant in some cases. The modern hard drives come with an advanced technology known as S.M.A.R.T. (Self Monitoring, Analysis and Reporting Technology). It is a proactive warning system that monitors the hard drive health on the basis of certain parameters and generates reports and warning messages on finding any fault. These parameters are sometimes denoted as hard disk reliability factors, such as temperature, excessive bad sectors etc. So, if a hard drive is anticipated to fail, SMART gives error message as:

"Pri master hard disk: S.M.A.R.T. Status Bad, backup and replace"

'SMART - Status Bad - Backup and Replace' Hard Disk Error and Recovery

Explanation

By master hard disk, error refers to the one, which is being primarily used by computer system to store data. The above warning suggests that users are required to immediately backup all data and replace the failing hard drive with a new one. Hard drives may go bad due to mechanical component failure, electronic faults or firmware corruption.

But in most of the cases related to physical failure, users may need to opt for Data Recovery service to recover their lost files. It can occur due to two basic reasons:

o Backup failure
o Ignoring the S.M.A.R.T error message

Hard Disk Recovery Service

It is a specialized component level service provided by recovery experts to recover data from physically failed hard drives. The processes involved in Hard Disk Recovery start with detailed analysis of the failed hard drive and chalk out suitable recovery procedures accordingly. A physically failed hard drive gets dismantled in sterile lab environments of Clean Rooms and technical procedures like repairing or replacing disk internals, disk cloning, shifting the platters etc. are applied. Data Recovery service experts can recover data in all cases of failures including those which S.M.A.R.T. can't detect.

Stellar Information Systems Limited offers industry's leading Hard Disk Recovery service through Class-100 Clean Rooms. We have been providing recovery service from more than 16 years. The advanced recovery service is provided for almost all makes and models of hard drives as SCSI, SATA, EIDE and IDE including server hard drives and SSDs (Solid State Drives).

How to Fix Hard Drive Read Errors and Data Loss Problems

If your Windows operating system is installed on primary hard drive partition, which is formatted using NTFS file system and you reformat the same partition during setup for clean installation, the partition is automatically formatted as FAT. It copies files from boot disk and then tries to restart your system in GUI mode to proceed with the installation.

However, the installation process fails and your system becomes completely inaccessible. You can not log into your system and gain access of your hdd data. This behavior leads to significant data loss, if there is no backup in place. At this point, you need to go for hard drive recovery to get your valuable data recovered.

In a practical scenario of this problem, the installation process fails and your system stops responding. Furthermore, you come across the below error message:

How to Fix Hard Drive Read Errors and Data Loss Problems

"DISK READ ERROR OCCURRED."

To fix this behavior, if you boot your system using MS-DOS disk and then run disk repair utility, you come across further error message stating:

"The media descriptor byte is invalid.
FAT copies are not the same.
Many crosslinked files.
All directory entries were invalid."

The partition repair and hdd data recovery process fails. Corruption remains intact and it does not even allow you to resume the installation process.

Cause

Microsoft Windows always formats the primary partition using FAT file system, and then it converts to NTFS. When you select to format system or boot partition using NTFS file system, Setup inadvertently writes 16 sector NTFS boot area on newly formatted FAT file system partition after file copy process completes. The problem may also occur if the partition is either damaged or corrupted.

Resolution

To sort out this behavior and recover hard drive data, go through any of the below steps:

During Setup process, remove primary NTFS partition and then re-create partition to format it as NTFS.

Install Windows operating system on FAT file system and then convert the FAT file system to NTFS.

If the above methods doesn't work, format the drive and reinstall operating system. However, this process removes all your valuable data from the HDD and requires hard drive recovery software to retrieve data. The applications are capable of easily, quickly, and safely recovering your valuable data in all data loss situations.

Stellar Phoenix Windows Data Recovery software recovers lost data from all types of hd drives, including IDE, EIDE, SATA, SCSI, and eSATA. The software is designed for Microsoft Windows 7, Vista, 2003, XP, and 2000. It salvages lost Windows data from NTFS5, NTFS, FAT32, VFAT, FAT16, and FAT12 file system partitions.

How to Backup Your Data Properly

Your data is important to you and why shouldn't it be. Computers have grown to be a part of our daily lives, so it's safe to say that most of us would be devastated if we lost everything on our computer. That is kind of a scary thought as your data depends on a machine to keep and store it, and let's face it, machines fail. Although computers have become much more reliable, more complex software and the internet has made everyone's computer vulnerable to complete loss of data.

There is something you can do to fight back though, that is to take matters into your own hands and don't rely solely on your computer. The best way to do this is to backup your data properly and keep doing that at least once a week, or once a day, depending on the type of data that you are backing up. This is perhaps the most important task that any computer owner can do, and is the simplest, but yet not everyone does it.

On the computer market these days there are a slew of external and internal storage devices that make backing up your data easy and convenient. With so many devices, and so many solutions, it can be tough for someone to decide on a backup method. So let's talk about the different backup strategies you could implement and which one best suits your needs.

How to Backup Your Data Properly

Known worldwide basically as the main method of backing up your data is your floppy disc drive. I know they store a very little amount of data, but for simple data files it's perfect because every computer already has one, and it is easy to use and access. I thought I would remind everyone of that backup method because it still can be used and won't cost you anything more.

Now if you want to get down and serious, and backup everything on your computer, then what you want to do is a full hard disk backup. A full hard disk backup is what every computer users should do, and is perhaps one of the best data backup solutions possible. This is true because it makes a full copy of your hard drive, so if all data is lost then your backup could be used immediately and will have everything on it. The only problem with this backup strategy is that it takes a little while to complete the backup, and to get the best use out of it, you should do it once a week. But if your data is really that important, then it is worth the time and energy to do this.

The next backup solution is pretty common and has already been done by just about everyone. You could just backup your data files and folders that are important to you, so if you ever lose all of your data, then you would still have your important files and only have to reinstall the software associated with them, if any. Files and folders are usually the most important type of data that someone needs to back up and is all that matters, so most of you should use this method.

Perhaps the best backup solution there is, next to a full hard disk backup, is a CD or DVD burner. Now since both of those burners cost around the same price, DVD is just a little more, then I recommend a DVD burner. Not only does DVD technology hold more then four times as much data as a regular CD, but a DVD burner will also burn regular CD's. Also not to mention that fact that you can backup your home movies that then can be played in your DVD player, and can last forever without degrading in quality like VHS.

Well those are the main types of backup strategies and solutions that people are using these days. Whether you run a business on your computer, or just use it for fun, backing up your data is always a good idea and should never be overlooked by any computer user.
