How Does Data Get Destroyed?
- Clearing: Clearing is a process that aims to prevent the recovery of your data. The process involves the act of overwriting or duplicating a fresh layer of redundant information to substitute the ones that have been removed. The overwriting operation is done numerous times to ensure the entire deletion of original data.
- Eliminating: However, the procedure often results in the original storage medium being unreliable, which in turn affects its market value. It involves degaussing, which employs a magnetic field to destroy data contained on a hard disk.
- Destroying: Destroying refers to employing physical techniques to guarantee that the storage device (and, by extension, the data on it) is made physically unreadable. The media device will be useless after enduring physical devastation. Destroying involves procedures like hard disk shredding and cremation.
What is Data Destruction?
Data Destruction is a software-based method of data sanitization that aims to fully destroy all electronic data stored on a hard disk drive or other digital media by overwriting data onto all areas of the device in an irreversible process. In data destruction, the data remains on the memory chip or hard drive of the device after deleting a file and the user can see the data.
In this process, data is rendered and unretrievable, either by erasing the electronic media or by replacing the data with random information. In this article, we will learn about types of data destruction, how data gets destroyed, and its importance.
