Or maybe you are selling your computer and you don’t want the new owner to have access to your data. Whatever the reason, it’s a great way to permanently delete data from a hard drive.

What is degaussing?

This is the process of using a magnetic field to erase data from a hard drive. The degausser generates a magnetic field that is strong enough to scramble the data on your hard drive. This process is irreversible, which means that once the data is gone, it’s gone for good.

Can a hard drive be re-used after degaussing?
No, degaussing destroys the data on a hard drive, which means that the hard drive is no longer usable. This is because the the alterations made to the magnetic field on the hard drive by the degausser make it impossible to store data on the hard drive again.

Can I recycle a degaussed hard drive?

Yes, a degaussed hard drive can be recycled. The precious metals in the hard drive, such as gold and silver, can be extracted and reused. The degaussed hard drive can also be shredded and used as raw material for other products.

How much does degaussing cost?

The cost depends on the size of the hard drive and the degaussing method used. The cost can range from $50 to $500.

How to choose a company that offers degaussing?

When choosing a data destruction company, it is important to consider the size of the hard drive and the type of degausser that is best suited for the job. It is also important to consider the cost of degaussing and the company’s reputation. Check for accreditation from the National Association for Information Destruction (NAID). NAID-certified companies have been vetted and meet high standards for degaussing services. They will offer you a certificate of destruction after destroying your hard drive.

Does degaussing work on SSD drives?

Degaussing only works on magnetic media, so it will not work on SSD drives because they do not have any magnetic media to degauss. You can, however, use a degausser on traditional hard drives that spin and have platters with data encoded on them in a magnetic fashion.

Alternatives to degaussing?

If degaussing does not work on your particular type of drive, there are a few other methods of data destruction that may work. These include physical destruction, which involves breaking the drive into pieces, and thermal destruction, which uses high heat to melt the drive and render it unusable.

Another alternative is to wipe the drive using special software that overwrites all of the data on the drive with zeroes or ones. This method is not always 100% effective, however, as there are some programs that can recover data from drives that have been wiped in this manner.
