Data Destruction Methods: A Comprehensive Guide The ways to destroy data are limited in number and the one thing that is common among all the ways is to dispose of data in a secure and safe manner. When data is not disposed of in a secure manner; businesses run the risk of exposing client information, information insurance and security arrangements. Before selecting a method of hardware data destruction, your business should consider multiple factors. These include the time spent on data destruction, the amount of hardware to go through during the process of destruction, etc. Let us have a look at the different types of data destruction available for your business and how you can select an appropriate method to dispose of your data: Overwriting When you have data that remains on disks and storage media even when you have erased it, then the most common method to get rid of it is to overwrite your media with new data. The process is also called sanitization/data wiping and when the data is overwritten in this manner, the pattern of 1s and 0s is written over the actual information. At times, a random pattern is made use of but a set of patterns can also be utilized. This makes way for later verification that drive has been completely wiped. As overwriting the data on hard drive is done with the help of software and is used in a selective manner on all or a part of storage medium, it is a comparatively easy option for certain applications. Overwriting is an eco-friendly option of but the process can be a time-consuming one in case you are trying to overwrite the entire high-capacity hard drive. It is a cost-efficient method when compared to other methods. You just need to have the manpower to manage it and buy software licenses per drive. Physical destruction Business can choose from a range of methods of physical data destruction like melting, pulverizing or disk shredding. Physical destruction needs to be carried out solely with the help of high- powered equipment. With the developments of technology, it has become possible to retrieve data even from damaged hard drives. We can conduct the process of data wiping before physically destroying the disk to make sure a comprehensive process of hardware data destruction is conducted. When the process of physical data destruction is carried out in a proper manner, it offers the greatest assurance of data being completely disposed of. There is a negligible chance that someone will be able to recover or reconstruct the data from a hard drive or disk that has been destroyed via the process of physical data destruction. This process of data destruction is a costly one because of the high capital expenses involved and the heavy machinery required. The physical method of data destruction contributes to electronic waste and negatively impacts the carbon footprint of companies and individuals. Degaussing Degaussing uses high-powered magnet to disrupt the magnetic field of things like magnetic tapes, floppy disks and hard disks. It is done with the help of a degausser. Data becomes completely unrecoverable with degaussing and the process does not require much time. Degaussing reduces the labor and time needed to overwrite information and prevents the retrieval of information of an organization by data recovery software thereby boosting your organization’s security from foreign threats. Degaussers can be heavy and expensive and their electromagnetic field can be powerful enough to produce collateral damage to any vulnerable equipment in the vicinity. Although the process of degaussing makes mediums entirely inoperable, there is no way to make sure that data has been destroyed without utilizing expensive forensic methods like electron scanning.
