Data recovery

When files have been deleted and the user wants to get those files back, data recovery is necessary. This is the act of retrieving deleted or erased files using one of several methods. One example is third-party software, which can be purchased and used to recover files. There are many software utilities that can perform data recovery successfully, ranging from $20 to $200, depending on how well the data is recovered.
There are also companies that will perform data recovery for a range of fees. Data recovery companies specialize in difficult cases of data recovery and when a software utility was not successful. These companies use more complex processes to retrieve deleted or erased data, processes that may not be used by third-party software. For example, a hard disk drive that has been in a fire may have to have its interface board or other parts replaced before data could be accessed.
