How To Recover Hard Drive Data?

Hard Drive data recovery is the process of recovering lost data from a hard drive when the data cannot be readily accessed through normal retrieval methods. Whether your hard drive has locked up or has completely crashed there is a good chance the data can be recovered by using a variety of hard drive data recovering techniques.
Reasons for Hard Drive Crashes
Hard drive crashes occur for a variety of reasons. One of the main causes for a full blown hard drive crash is generally attributed to a hardware issues. The hard drive is a magnetic disc which spins and has an extended arm that collected data from any area of the hard drive. If the arm fails to function or the motor overheats or stops spinning, then there is a chance your hard drive will crash rendering data seemingly inaccessible from all hard drive areas. Hard drive crashes can also be caused by corrupted registry files or system files. Viruses, Spyware, adware, and Trojan horses can also cause system file corruption resulting in a hard drive crash.
Determining the Actual Cause of a Hard Drive Crash
To determine whether your hard drive has crashed due to mechanical failure or a software related problem is relatively simple. Check whether the flashing light in front of your computer case is blinking or not. If the light is flashing but the computer is not booting up, then the problem may be software related; and in most cases the cause is either virus related or due to a corrupted system file. These types of hard drive crashes can generally be recovered by reinstalling the operating system.
If the flashing light in the front of the computer case is not blinking, it indicates that there is no hard drive activity and is generally attributed to a mechanical problem. In this scenario a qualified computer technician may be needed to fix problematic hard drive issues.
Physical Damage
Most physical damage to a hard drive, such as failed motors or head crashes, cannot be repaired by typical computer users. Physical damage of a hard drive often results in some data loss and in most cases you may not be able to recover all the lost data. However, the physical damage can also result in the damage of the logical structures of the file system which prevents file system structures from being completely written to the hard drive.
If the hard drive has any physical damage, you need to seek a technical expert to assist in recovery or choose a data recovery company to recover as much data as possible. Most hard drive data recovery firms utilize the latest tools like magnetometers to retrieve the lost bits from the magnetic media. The recovered raw bits from the damaged hard drive are used to construct a new disk image, and the logical damage can be repaired.
The Role of Hard Drive Data Recovery Software Programs
Hard drive data recovery software programs play a major role in recovering hard drive data. You will find several companies that offer these types of programs. Most will automatically create backup copies of all your files and folders reducing the worry of potential data loss. A good hard drive data recovery program can recover all the important files or folders which vanish after partition loss, accidental format, file or directory deletion, software malfunction or even a virus attack. Whether you accidentally delete the files or your computer crashes, data recovery software can locate the lost files and recover them from your hard drive.
The main contexts where hard drive data recovery software is found useful include:
1. Missing file or directory
2. Formatted hard drive
3. Deleted file or directory
4. Unbootable hard drive
5. Inaccessible hard drive
6. Recovery of deleted files and folders on FAT and NTFS hard drive or partitions
7. Data recovery on damaged FAT and NTFS partitions
8. Damaged or corrupted partition table
The majority of hard drive data recovery software programs currently available is easy to install, user friendly, and is virtually self maintaining. However, it's a good idea to purchase these programs from a trusted software supplier.
Most software companies understand the consumer's need to be assured of value and ease of use, so if the data recovery software you selected has a trail offer, it may be a good idea to give it a test drive before you make a purchase.
