How many times have you experienced that sickening feeling when your hard disk suddenly fails? How many times have you experienced that your hard drive just does not start and all data can be gone forever? A hard drive failure is one of the most common and worst nightmares faced by operators of computers around the world. Precious data is lost, either at home or in large corporate environments. What can you do in these situations? Well, there are some solutions that can be done by you in order to revive the hard drive. Let's talk about the solution below. First, let's discuss why a hard drive fails.

If the data on the hard disk can be recovered or not depends on the magnitude of the problem. A hard disk may be damaged due to corruption of the firmware, electronic failure, mechanical failure or an error of logic. Many times the hard drive, you could lose data due to the combination of the above factors. A hard disk can also develop bad sectors, because the data on the sectors is lost or becomes unreadable.

Firmware refers to information used by the computer to interact properly with the hard drive. If the firmware fails or becomes corrupted, important data on the hard disk is lost. In the case of an electronic failure that may occur an electrical charge that can knock the controller board on the hard disk and make it unusable. However, the data can be recovered by data recovery experts using special software for data recovery. Exchange of the other controller card can be dangerous as the information on the controller card is exclusive to the hard drive in which it is mounted. Compared to electronic failure mechanical failure can be worse than the data recovery can be almost impossible. A mechanical failure include head crash and read / write head. Head crash can occur due to shock, power surges and movement of the computer. Next come the logical errors. Logic errors have nothing to do with the hardware. Logical errors can occur due to file system corruption on the hard disk or incorrect entries in the file allocation table.

In case of hard drive failure is vital to call the data recovery experts. In most cases, information on the hard drive is important, and you can not bear to lose. Experts increase the chances of hard drive recovery in case of disk failure due to software malfunction, virus attacks and other reasons mentioned above. Data can be recovered in any operating system, including all versions of Windows and Apple Macintosh, Novell, Linux, Unix and EXT2 in all types of file systems like FAT, FAT32, NTFS, NTFS5, HFS, HFS +, NWFS, and EXT3. Experts can have the hard drive of your workshop in order to recover lost data and send it back to you in a few days. Most data recovery experts have their own laboratories involved in testing the hard drives and repairs.

Data loss is the last thing you, the customer will want. This is where data recovery experts come into play. You can not extract only the data from hard disks, but also recover data from tape drives, CD, DVD and other storage media important. You as the consumer can take some preventive measures, such as backing up all important data at least once a week. Windows has its own program rich in security features. There are other software backup on the market that can prevent a possible disaster.

In addition to concerns the recovery of data, another problem is the time you can take to an expert to help. This can be slow and tedious. I recommend having a second full system source such as a laptop (for portability) that can continue their work. In this way are never completely and can share important data between the two.
