What is Hard Drive Wipe?
Data remanence is the residual representation of data that remains even after attempts have been made to remove or erase the data. This residue may result from data being left intact by a nominal file deletion operation, by reformatting of storage media that does not remove data previously written to the media, or through physical properties of the storage medium that allow previously written data to be recovered. Data remanence may make inadvertent disclosure of sensitive information possible, should the storage media be released into an uncontrolled environment (e.g., thrown in the trash, or given to a third party).
Various techniques have been developed to counter data remanence. These techniques are classified as clearing, purging/sanitizing or destruction. Specific methods include overwriting, degaussing, encryption, and physical destruction.
Effective application of countermeasures can be complicated by several factors, including media that are inaccessible, media that cannot effectively be erased, advanced storage systems that maintain histories of data throughout the data’s life cycle, and persistence of data in memory that is typically considered volatile.
Several standards exist for the secure removal of data and the elimination of data remanence.
There are three levels commonly recognized for eliminating remnant data:
Clearing is the removal of sensitive data from storage devices in such a way that there is assurance that the data may not be reconstructed using normal system functions or software file/data recovery utilities. The data may still be recoverable, but not without special laboratory techniques. Clearing is typically an administrative protection against accidental disclosure within an organization. For example, before a hard drive is re-used within an organization, its contents may be cleared to prevent their accidental disclosure to the next user.
Purging or sanitising is the removal of sensitive data from a system or storage device with the intent that the data can not be reconstructed by any known technique. Purging, proportional to the sensitivity of the data, is generally done before releasing media outside of control, such as before discarding old media, or moving media to a computer with different security requirements.
The storage medium is physically destroyed. Effectiveness of physical destruction varies. Depending on recording density of the medium, and/or the destruction technique, this may leave data recoverable by laboratory methods. Conversely, physical destruction using appropriate techniques is generally considered the most secure method available.
