Data recovery
Data recovery is the retrieval or restoration of digital information that is no longer accessible for some reason. An example would be any file that was mistakenly deleted, lost, or corrupted. The data recovery process varies based on the circumstances under which it was lost. In more serious situations, data recovery may involve recovering the data from a hard drive that was destroyed in a fire, as shown in the picture.
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 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 was in a fire and needs its disk interface board replaced before data can be recovered.
