Data recovery is the act of salvaging data stored on damaged media, such as magnetic disks and tapes. There are a number of companies and software products that can help recover data damaged by a disk crash or computer virus. Of course, not all data is recoverable, but data recovery specialists can often restore a surprisingly high percentage of the data on damaged media. The ability to recover "deleted" data is a problem when equipment used to store sensitive data is to be discarded.
Data recovery cases can be divided up into two main categories, caused by
- Logical failures - filesystem corruption resulted by power-cuts, software bugs, misuse or viruses.
- Physical failures - damage of the mechanical parts or media firmware. These cases are usually more complex to recover.
Whether common or complex, each data recovery case is unique and the process can be very resource extensive and exceedingly technical.
