Data erasure (sometimes referred to as data clearing, data wiping, or data destruction) is a software-based method of data sanitization that aims to completely destroy all electronic data residing on a hard disk drive or other digital media by overwriting data onto all sectors of the device in an irreversible process. By overwriting the data on ...
Methods used in sanitization range from simple overwrites to destruction of the cryptographic keys for encrypted data (the technique is known as cryptographic erasure) to physical destruction of the storage media. This standard provides guidance to help organizations select the proper sanitization methods for their data.
Apart from overwriting, other methods could be used, such as degaussing, or physical destruction of the media. With some inexpensive media, destruction and replacement may be cheaper than sanitisation followed by reuse. ATA Secure Erase is not approved. Different methods apply to different media, ranging from paper to CDs to mobile phones.

Companies can mitigate these risks by requiring waivers of liability, audit trails, certificates of data destruction, signed confidentiality agreements, and random audits of information security. The National Association of Information Destruction is an international trade association for data destruction providers. [34]

Data sanitization has a wide range of applications but is mainly used for clearing out end-of-life electronic devices or for the sharing and use of large datasets that contain sensitive information. The main strategies for erasing personal data from devices are physical destruction, cryptographic erasure, and data erasure.
Data remanence is the residual representation of digital 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 media that allow previously ...
