What Do You Know About Technology

Erase Hard Disk Data Completely Using a Degausser If you are like most people, you probably have no idea what degaussing is. In a nutshell, degaussing refers to eliminating or reducing unwater data that is stored on a hard drive. The data on a hard disk is usually stored on a magnetic strip. Degaussers work by producing a strong magnetic field. When a data storage device such as a hard disk is put in the magnetic field of a degausser, the data stored will be erased/ Erasing data on a hard disk with your PC does not completely erase it. The data that is deleted is usually stored on a compartment of the hard disk that can be accessed through different recovery processes. The only sure way of completely wiping data off your hard drive is through degaussing. In fact, most companies and business institutions use degaussing to erase data on their hard drives. How a Degausser Works When you know how data is stored on a hard drive, it becomes easy to understand how degaussing works. Hard drives have a magnetic tape inside where the data is recorded. When your PC is turned on and the hard drive plugged, the computer will read the data on the magnetic strip and convert it to digital format. The digital format is what the end users see in form of text, video or audio from the hard disk.
5 Lessons Learned: Options
When you put a hard disk on the magnetic field of a degausser, the magnetic strip is destroyed. The data becomes randomized as the magnetic field destroys the magnetic strip. This makes it impossible for the data to be recovered when the hard disk has been put next to a Degausser.
Valuable Lessons I’ve Learned About Resources
Types of Degaussers You can choose different types of degaussers in the market to purchase. Before choosing one to buy, you should research well. Since not all degaussers work in the same way, it is only logical to research before buying. Electronicmagnetic degaussers are among the most common in the market. The degaussers charge a degaussing coil to produce a magnetic field. The other type of degaussers you can purchase are the permanent magnet ones. You can operate these degaussers without electricity since they usually have a rare earth magnetic. There are also specific uses that a degausser may be made for. For instance, you can purchase degaussers that are specifically meant for mobile operations. One of the most important things to consider when choosing a degaussers is its ability to erase data. The maximum magnetic field strength of a degausser determined its performance. If a degausser has a stronger magnetic field, it’s performance is also bound to be higher. The above information is a summary of how degaussers work and how you can determine the right one to buy.
