What Degaussing a Hard Drive Entails Learning how to degauss a hard drive may interest you if you intend on permanently remove all the data held in it for purposes of safe disposal or recycling. Degaussing is a kind of demagnetizing that involves subjecting an object like a hard drive to a magnetic field that has a stronger, fluctuating intensity. The strong magnetic field is created via a machine referred to as degausser. Upon exposure to the strong, changing magnetic field, the magnetic charge of your hard drive is reset to a neutral state. In the event a memory device has its magnetic charge reset to neutral, it permanently loses all the data it contains. If you’re planning on buying a degausser to erase the data in your hard disk, just know that there are different types of the devices that use varying degaussing technology. Available for purchase are degausser using coil, capacitive, or permanent magnet technologies. A coil degausser employs a steel core that’s wrapped in copper wire, which generates a fluctuating electromagnetic field when powered up. Provided that the degausser is powered on, the electromagnetic field stays, which can cause the coil to overheat. To prevent the overheating of the coil, an ac degausser should have a restricted duty cycle. Degaussing machines that have larger coils have fans that help cool the coil while extending its operating cycle.

A degausser that’s powered by capacitive discharge technology creates and stores energy in massive capacitors. When powered up, the capacitors are fully charged with energy, after which they discharge to form an extremely strong electromagnetic pulse. There is a short-lived burst of energy that does not overheat the coil during the degaussing process. For that reason, capacitive discharge degaussers have a longer duty cycle. Since the manner in which energy is discharge may be referred to as pulse, capacitive discharge degaussers may also be defined as pulse degaussers.
5 Key Takeaways on the Road to Dominating Resources
When you need the capacity to use a degausser continuously, such as seven days a week, try the permanent magnet type as it involves no electronic component that’s vulnerable to overheating. These degausser types may have magnets of different sizes, and the larger types have the ability to generate extremely strong magnetic fields. If you want to degauss any memory device, be sure that you’re done using it because there’s a chance that it cannot be used again on your computer once degaussed. Devices such as hard drives use servo tracks that carry information which helps the computer interface with them for reading purposes. Degaussing wipes off the servo tracks plus all other data, making it impossible for your computer to recognize the device in its degaussed state.
