In this era where computer rules, data plays the most important role in our life. So the fear of data loss and the damage we might occur is most devastating. To over from such losses data recovery software has evolved which salvage our lost data. Either the data lost occur due to software malfunction, viruses, file/directory deletion or even sabotage. But these data recovery software are only helpful from logical crash recovery.

The cause of data getting corrupt are varied, this may be of the following reasons

• Improper shut down of computer system.
• Due to power surge computer resets of it own, this freezes the computer making the shutdown impossible leading to data loss

This type of failure can be recovered by using data recovery software.

• Due to catastrophic hard drive failure where operating system is unable to recognize the hard drive
• Head getting crash
• Due to air pollution inside the drive (This generally occur while not keeping the system in the clean environment)

Failure from such physical crash can recover by using data recovery service. This requires Clean Room Facility where data recovery experts know how to recover data from it.

• Hard drive failure due to bad sector also. When certain sector of the hard drives becomes unreadable its content are copied to spare sector before it becomes completely damaged. Once the sector is not readable at all so data recovery from such bad sector is not possible

Although data recovery services are able to recover from the most critical situation but sometimes it also fails. So there is no scope left to recover the lost and damaged data from such failures. Sometimes data recovery service is as simple as downloading a free data recovery software, other times its more complex where disk imaging technique is required

So the best way to avoid such situation where even data recovery service is not possible is to keep regular back up. To stop the drive getting corrupt runs disk defragmenter every three month to keep it in good condition. While moving from the system from one place to another always pack the hard drive in original packing material so that drive doesn’t get damage.
