Degaussing a hard drive is a way of erasing the data permanently using a powerful magnetic field which disrupts the magnetic domains on the hard drive platters, which renders the data unrecoverable.
Degaussing a hard drive is a process which destroys the magnetic alignment of the hard drive completely, which makes the hard drive unusable and the data inaccessible.
Degaussing the hard drive completely sanitizes the media of data in seconds by delivering a powerful magnetic pulse that instantly destroys all magnetic domains on the disk platters.
Hard drives store data by magnetizing tiny areas called domains on the platters of the hard drive.
When you deguass a hard drive you use a strong magnetic field to neutralize or randomize the magnetic domains which destroys the data patterns.
Degaussing hard drives is done to securely erase any data from hard drives, especially when the hard drive is being recycled or decommissioned or when any sensitive information on the hard drive requires being permanently removed.
The degaussing of a hard drive is a highly effective way of data destruction and the data that is on the degaussed hard drive is considered unrecoverable.
Deguassers for hard drives are specialized machines which generate a powerful magnetic field that is needed for degaussing.
Shredding of hard drives is also another destruction method of destroying data on a hard drive.
