Degaussing and Frequently Asked Questions

Where can I purchase Garner data elimination equipment?

You can purchase directly from us or through our extensive network of dealers and distributors around the world. For more information, contact us by email at or by phone at 800-624-1903.

Is the magnetic field generated by your degaussers safe?

According to the results of a multi-year study by the World Health Organization (WHO), “Despite extensive research, to date, there is no evidence to conclude that exposure to low-level electromagnetic fields is harmful to human health.” Also, the amount of magnetic field exposure to people 12 to 18 inches away from a Garner degausser is extremely low, approximately 1/120th of the limit recommended by the American Conference of Industrial Hygienists, the scientific body that issues exposure recommendations for magnetic emissions. For more information, download our white paper, Magnetic Fields Discussion.

Why is degaussing considered to be the best way to erase data from hard drives and tapes?

Degaussing eliminates data physically (not via software) from the hard drive platters or tape film by producing a magnetic field sufficient to neutralize the magnetic particles.  Sanitization methods such as overwriting, secure erase, shredding, physical destruction or encryption leave data that could potentially be recovered through software or laboratory methods available now or in the near future.  Degaussing with a machine that produces sufficient field strength produces permanent erasure. Data on degaussed media is gone and cannot be recovered with existing or future technology. Visit our White Paper section for more in-depth information about the degaussing process.

Will degaussing erase data contained on solid-state hard drives (SSDs) used in laptops and tablets, flash drives, USB thumb drives, etc.?

No, solid-state drives and other flash media do not use magnetic technology to store data. Instead, the data is stored on memory chips, which must be physically destroyed.  Piercing the drives to break the chips eliminates data, as long as all chips are destroyed.

Where are Garner’s degaussers and physical destroyers made?

Garner’s degaussers and destroyers are wholly made and manufactured in the USA. We start with raw materials which we machine into parts and then assemble into final products in-house. For more information on how we make the magic, read our Made in America article.
