With the advancement in technology, there are several new methods for data storage. But, despite the constant growth in the reliability of storage devices, the loss of digital information is a major reason to worry. General causes of data loss may include human errors, software malfunctions, power outages or hardware failures.
Most of the times, any information stored on a digital medium is almost recoverable. However, you cannot recover a document which was written but never saved on to the storage drive.
