What is Degaussing. Degaussing is simply the act of erasing data from magnetic media. Sometimes it is referred to as sanitization.. It works by subjecting magnetic media to a strong magnetic field that removes data from data bearing surfaces. The magnetic field can be created either by powerful magnets or an electromagnetic discharge.
Another way to permanently erase a hard drive is to use a degausser to disrupt the magnetic domains on the drive-the very way that a hard drive stores data. Some NSA approved automatic degaussers can erase dozens of hard drives in an hour and cost tens of thousands of dollars US.f you want to erase a hard drive, but also want it to work properly after being erased, you must erase the drive using data destruction software (option 1, above) instead. Note: For the average computer owner or organization, degaussing probably isn't a cost effective way to completely erase a hard drive.
