Data security<\/a> has become one of today\u2019s hottest topics, and with very good reason. Some of the world\u2019s largest organizations – think TD Bank, Starbucks, Apple, even the U.S. government – have been victims of data breaches<\/a>!<\/p>\n Organizations of all sizes should be taking steps to keep their data safe. But while IT security specialists and cyber security firms are your first line of defense, they can\u2019t do much about protecting data on hardware that\u2019s been decommissioned.<\/p>\n If you want to safeguard your unwanted hard drives, the solution is simple in data destruction<\/a> terms: destroy them digitally<\/em>, magnetically<\/em>, or physically<\/em>.<\/p>\n When it comes to digitally destroying a hard drive, the options include:<\/p>\n All of these mean essentially the same thing – your data is removed from a hard drive and can\u2019t be recovered. But the most accurate term for digital data destruction is overwriting<\/em>.<\/p>\n Most software that\u2019s designed to erase your hard drive actually writes over the existing data with new data in the form of binary code (a series of zeros and ones). The most widely recognized erasure standards in North America are the U.S. Department of Defense (DoD) single, 3 pass, or 7 pass patterns<\/a><\/strong>, and the NIST (National Institute of Standards and Technology) SP 800-88<\/a><\/strong>, which provides direction on wiping methodology.<\/p>\n Erasure is the preferred method where data destruction is concerned because, if successful, it allows your hard drives to be re-used. But like many other digital processes, erasure software can be subject to failure.<\/p>\n You should also recognize that formatting<\/em> or re-formatting<\/em> a hard drive is not<\/em> the same thing as wiping it. Re-formatting a hard drive simply hides the data it contains, allowing a specific area of that drive to be re-used. In other words, your data is left intact – and it can be recovered with the help of special tools.<\/p>\nDigital Data Destruction<\/h2>\n
