How Degaussing a Hard Drive Works

The risks of data breaches and identity theft only continue to grow. While the most common image of a data breach involves the digital world, it can and does happen in the physical one too. Old hard drives are a prime source, and if the right steps aren’t taken to destroy the data on them, they can lead to costly and damaging data breaches. There are a few reliable ways to destroy a hard drive, and degaussing is one of those options. 

The Difference Between Hard Drive Destruction and DegaussingThe Importance of Destroying Data on a Hard Drive

All information and historical data from your computer rests on your hard drive. From pictures, to emails, to passwords, a wealth of personal data can be found if someone accesses your hard drive. 

Since computers don’t last forever, it’s important to make sure that the data on the hard drive gets destroyed when you switch or upgrade computers. One of the most reliable ways to do that is by degaussing the hard drive.

What is Hard Drive Degaussing

At a basic level, hard drive degaussing erases all of your information using a magnetic field. 

When a hard drive platter spins under a read/write head, it generates small pulses of electricity that magnetize the platter surface as they pass through. By exposing the drive to another strong magnetic field, the drive’s magnetic properties are removed along with the data previously stored on the drive.

Hard drive degaussing machines vary in power, just as hard drives vary in size. While these machines are effective, if there’s a mismatch on machine and hard drive power, or if the process isn’t done properly, some data can still be recovered from the hard drive. 

Two additional factors, when compared to hard drive destruction and shredding, are cost and time. Degaussing takes more time, as the machines can’t handle a bulk order in the same way as a shredder. A degaussing machine also doesn’t scale with cost, as a drive must run through the process individually.

Hard Drive Destruction, the Alternative Option

The Difference Between Hard Drive Destruction and Degaussing

Hard drive destruction is the process of physically shredding the drives. When it comes to shredding, all of the information saved onto your hard drive is physically destroyed. 

Shredding ensures complete data destruction. Additionally, it offers the most security out of any method. When a hard drive gets torn apart, little room for error exists. Typically, hard drive destruction costs between $4-$12 per drive. In addition, as quantity increases, the price per drive goes down.

Which Disposal Method is Best

While both shredding and degaussing destroys the drives, they perform the function differently. The major variants are cost, time, and security. It’s important to consider the different factors before choosing. This will help you decide which option is best for you.
