Hard Drive Degausser: What Is It and How Does It Work?

Hard Drive Degausser: What Is It and How Does It Work?

Posted by Michelle Boyce on 2023 Aug 11th

Hard drive degaussers are essential tools for individuals and organizations that deal with sensitive data. These machines use powerful magnetic fields to scramble the data stored on hard drives, making it impossible to recover. While software-based data destruction methods can be effective, they're not foolproof, and there's always a risk of data leakage.

In this article, we'll explore the different types of hard drive degaussers, their benefits, and drawbacks, and help you choose the best degausser machine for your needs.

Types of Hard Drive Degaussers:

Electromagnetic Degaussers:

These degaussers use an alternating current (AC) to generate a magnetic field that is strong enough to erase the data on a hard drive. These are the most commonly used degaussers in professional data destruction services.

Permanent Magnet Degaussers:

These degaussers use a powerful permanent magnet to generate a magnetic field that erases the data on a hard drive. These are less expensive to operate as they require no maintenance or electricity and are powerful enough to erase all hard drives currently on the market today. Some permanent magnet units (Pro 1.4 Tesla Model) will also erase server grade hard drives with the removable sled/tray attached to them saving the operator from having to remove them before degaussing.

Benefits of Degaussing Hard Drives:

  • Data Security: Degaussing a hard drive is the most secure way to erase data as it permanently destroys all data on the drive, making it impossible to recover.
  • Compliance: Many industries, such as healthcare and finance, have strict regulations regarding data privacy and require the secure destruction of data. Degaussing hard drives helps companies comply with these regulations.
  • Cost-Effective: Degaussing a hard drive is a cost-effective way of disposing of old hard drives. Instead of paying for data destruction services, companies can purchase a hard drive degausser and do it themselves

Types of hard drive degaussers machine:

1. SD-1 Magnetic Media Degausser Hard Drive:

The Magnetic Media Degausser in the SD-Mobile Hard Drive Series uses Permanent Rare Earth "Fixed Magnet" Technology. The data on magnetic media devices, including PMR and LMR hard disk drives, hard drives, and floppy disks, can be fully erased using this device.

2. SV91M Hard Drive & Tape Degausser:

For the security-conscious, low volume operator who wants a high-quality, low-cost solution to remove magnetic media security risks, the SV91M Hard Drive and Tape Degausser is perfect.

3. DataGauss MAX and LG-MAX Hard Drive & Tape Degausser:

Compact and simple to use, the DataGauss MAX and DataGauss-LG MAX Hard Drive & Backup Tape Degaussers are now 3 times quicker, have a 10,000 Gauss field, and only take 7 seconds to charge. The DataGauss LG-MAX includes our custom Data Destruction Auditor data logging device as standard equipment.

4. V100 Bulk Eraser, Conveyor Degausser:

The V100 Bulk Eraser was created to satisfy the needs of large volumes of users. It is a conveyor unit that erases more than 75 dB on 1500 oersted tape in one pass while operating constantly.

In conclusion,

Hard drive degaussers stand as indispensable tools in the realm of data security and destruction. These devices utilize powerful magnetic fields to obliterate data stored on hard drives, ensuring irrevocable obliteration. While software-based methods have their merits, their inherent risks of data leakage remain.

This article delved into the various categories of hard drive degaussers, shedding light on their respective advantages and limitations. Electromagnetic degaussers, with their potent alternating currents, and permanent magnet degaussers, leveraging permanent magnets, offer distinct approaches to data destruction.
