How Data is Lost

Among various causes, data loss can be attributed to system or human error, adverse environmental conditions and device failure (see chart below).
Human causes of data loss include intentional or accidental deletion or overwriting of files. Virus damage, operating system or application software bugs, or failed upgrades may also cause data loss.
Common physical causes of data loss include power loss or power surge, overheating, electrostatic (static) discharge and any kind of physical damage to the storage device or medium.
