Do you know the individual data destruction methods? Do you know what is the difference between disk demagnetization (disk degauusing) and information destruction with software? Can you degauss flash media? Learn about the different methods of erasing data from storage media.<\/p>\n\n\n\n

DEMAGNETIZATION OF DATA CARRIERS<\/strong><\/p>\n\n\n\n

Demagnetization is an effective method of data removal from magnetic data carriers. To carry out it, it is necessary to use a special device, which is a degausser. It creates a strong magnetic field that disrupts the setting of the magnetic domains of the carrier: it destroys, for example, servo information and calibration information. The larger the capacity of a disk, the stronger the magnetic field is needed to erase the information it contains.<\/p>\n\n\n\n

PHYSICAL DESTRUCTION OF DATA<\/strong><\/p>\n\n\n\n

Another method of erasing data is to physically destroy the storage media. There are many shredders and destroyers on the market that physically damage the media by punching, crushing or shredding them.<\/p>\n\n\n\n

DELETION OF DATA BY USING SOFTWARE<\/strong><\/p>\n\n\n\n

This method consists in repeatedly overwriting data on the carrier, which makes it difficult to recover. But the software overwrites the data, so there is a chance that some of it will be still recoverable.<\/p>\n\n\n\n
