What's Involved in Degaussing a Hard Drive?

If you're considering how to degauss your hard drive, you probably want to have all data kept in it permanently eliminated so you can dispose or recycle the hard drive. 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 machine that generates the intense magnetic field is called a degausser. Upon exposure to the strong, changing magnetic field, the magnetic charge of your hard drive is reset to a neutral state. When the entire magnetic charge of the memory device is reset to neutral, all the data it contained is erased completely.

If you're planning on buying Drive Degausser http://www.drivedegausser.com/how-do-degaussers-work/ to erase the data in your hard disk, just know that there are different types of the devices that use varying degaussing technology. Available in the market are the coil, capacitive discharge, or permanent magnet degausser.

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.To read more about the importance of getting the best hard drive degaussing, go to http://itlaw.wikia.com/wiki/Degaussing .

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. 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. The way in which energy is release may be described as a pulse, and that's why capacitive discharge degaussers may also be referred to 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 data destruction are fitted with magnets of different sizes, and the bigger ones are capable of producing extremely intense magnetic fields.

If you seek to degauss any memory object, ascertain that you don't want it anymore as there's the possibility your computer won't recognize it after degaussing. Devices such as hard drives use servo tracks that carry information which helps the computer interface with them for reading purposes. Degaussing erases the servo tracks alongside all data, so there's no way your computer may recognize the memory device in its degaussed form.
