Data Recovery

What Is Data Recovery?

The definition of data recovery within the computing world, is the process of extracting data from storage media which is inaccessible using normal methods, due to physical damage of the media or corruption of the data structures.

The data from any storage solution can be recovered, whatever the format, ranging from enterprise level RAID storage arrays through laptop, desktop, server and external drives to any type of removable media, such CD, DVD, Blu-Ray and USB thumb drives.

When Is Data Recovery Required?

When the data stored on your storage device, including system and user files are no longer accessible due to logical or physical damage of the storage media, data recovery will be required in order to gain access to it.

Physical damage to your storage media can occur for several reasons, for example general wear and tear, overheating due to an extreme operating environment and impact damage such as dropping a drive or hitting it.

Any action which causes the data on the media to be altered causing corruption of the data, the file system or operating system is considered logical damage. Examples of how this can occur may be the result of a power failure, malicious software and system crashes. Deliberate or accidental deletion or reformatting of a data volume are also considered examples of logical damage.

The table below gives a range of scenarios for which data recovery will be required in order to gain access to your data.
