There are two types of failures. First one is the predictable and the other is unpredictable. Data disc recovery depends on which type of failure that is occuring.
Disk failure can occur during normal operations, or due to external factor such as exposure to fire or water or high magnetic waves, or suffering a sharp impact.

A Redundant Array of Independent Drives (or Disks), also known as Redundant Array of Inexpensive Drives (or Disks) (RAID) is an term for data storage schemes that divide and/or replicate data among multiple hard drives. RAID can be designed to provide increased data reliability or increased I/O performance, though one goal may compromise the other. There are 10 RAID level. But which one is recommended for data safety and performance considering that hard drives are commodity priced?
In data recovery it is NEVER a good idea to install, copy, surf the Internet, reboot the machine, or do ANYTHING on the hard drive you are now trying to recover the data from. I often tell customer they need to Slave the hard disk to another computer, or put it in a USB chassis. What is difficult is the fact that the average home user has no idea how to do this, and it can be a very daunting task.
In this guide I explain how to recover files from a laptop with crashed Windows OS. You can use same technique to recover files from desktop computers. I will be recovering files using Knoppix live Linux CD. You can follow my guide even if you have never used Linux before.
Definition: Data recovery is the salvaging of data originally stored on media such as magnetic disks and tapes and which has become corrupt or inaccessible.
Data is stored on media like hard disks, RAID configurations of hard disks, magnetic disks, tapes, CDs, DVDs, floppy disks and other storage media. Data gets damaged or missing in a variety of ways from virus attacks to improper storage of the media to accidents like floods. It could also have simply just been erased. Very often a large percentage of this data can be recovered using a variety of techniques.
