Data recovery refers to the act of recovering data which has been lost, corrupted or deleted. This process involves retrieving data from damaged, failed, corrupted, or inaccessible storage media when it cannot be accessed normally. This can be due to various reasons such as physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system. The most common data recovery scenario involves an operating system failure, malfunction of a storage device, accidental damage or deletion, etc. In these cases, the goal is simply to copy all wanted files to another disk. This can be easily achieved using a Live CD, many of which provide a means to mount the system drive and backup disks or removable media, and to move the files from the system disk to the backup media with a file manager or optical disc authoring software.
