How to Degauss Your Hard Drive
You may want to learn how to degauss a hard drive if you wish to permanently erase all data stored in it for safe disposal or recycling purposes. Degaussing is a form of demagnetization whereby a device like a hard drive is exposed to a magnetic field that's fluctuating and more intense. The intense magnetic field is generated by a machine called a degausser. Upon exposure to the strong, changing magnetic field, the magnetic charge of your hard drive is reset to a neutral state. In case the magnetic charge of the memory object resets to neutral, the data it holds is lost permanently.
In case you desire to get degauss a hard drive for the removal of data in your drive, be familiar with the different kinds of these devices that rely on different degaussing technologies. Available for purchase are degausser using coil, capacitive, or permanent magnet technologies.
The degausser with a coil has copper wire wrapped around a steel core, and when activated, an electromagnetic field is generated. Provided that the degausser is powered on, the electromagnetic field stays, which can cause the coil to overheat. To ensure the coil does not overheat, the ac degausser should be used on a limited operating cycle. Degaussing devices using large coils are fitted with fans for cooling the coil and prolonging the duty cycle.
A degausser that employs capacitive discharge technology produces and preserves energy in large capacitors. When activated, the capacitors are filled with energy, which they then release to create a highly intense electromagnetic pulse. Because the burst of energy is short-lived, it does not allow the coil to overheat throughout degaussing. That's why capacitive discharge degaussers have a continuous 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.

In case you seek the capacity to run a degausser without stopping for may be seven days a week, choose a permanent magnetic type since it has no electronic part that's prone to overheating. These varieties of degaussers are fitted with magnets of different sizes, and the bigger ones are capable of producing extremely intense magnetic fields.
If you intend to degauss any memory device, ensure that you no longer need it as there's the likelihood that it may not be recognized again by your computer upon degaussing. 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. Know what is degaussing a hard drive here!
