Data recovery is the process of retrieving or restoring digital information that is no longer accessible for some reason. A good example would be any file that has been mistakenly deleted, lost, or corrupted. The data recovery process varies based on the circumstances under which it was lost.
How is data recovered?
One solution is third-party software. Many software utilities can recover lost data. In price, they range from $20 to over $200, depending on their capabilities. There are also companies that will perform data recovery for a range of fees. They specialize in difficult cases where a software utility was not successful and part replacement is necessary. An example is a hard drive that has been in a fire and needs its disk interface board replaced before data can be recovered.
