Overview of How Degaussers Work Many people do not what degaussing is. Basically, degaussing refers to the complete erasing of data from storage devices such as hard drives, memory drives and others. Most hard disks usually store the data transferred on a magnetic strip. Degaussers produce 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/ In most cases, erasing a hard disk using a 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. Degaussing is the only sure way of completely erasing the data on a hard disk. This explains why government institutions and corporations usually use degaussing to erase date on their drives. How a Degausser Works The easiest way to understand how a Degausser works is to start at looking at how data is usually stored on a hard drive. In most hard drives, data is usually stored in a magnetic strip that is inside them. When you plug the hard drive on your laptop, the magnetic strip data is read and converted to digital format. The data that has been converted to digital format can then be accessed on the PC in form of files.
Short Course on Resources – Covering The Basics
The magnetic strip of a hard disk is destroyed when the storage device is introduced into the magnetic field of the degausser. When the magnetic strip is destroyed, the data stored on it is randomized. This makes it impossible for the data to be recovered when the hard disk has been put next to a Degausser.
What No One Knows About Options
Buying a Degausser You can choose different types of degaussers in the market to purchase. Before choosing one to buy, you should research well. You should research well to find the right degausser for your needs. The most common degaussers are the electromagnetic type. The degaussers charge a degaussing coil to produce a magnetic field. You can also go for permanent magnetic degaussers. These degaussers do not require electricity to operate and have one or more rare earth magnets. There are also specific uses that a degausser may be made for. For example, some degaussers are made for mobile operations and others for high volume work. One choosing a degausser, one of the important things to consider is its performance in data eraser. The maximum magnetic field strength of a degausser determined its performance. The higher the magnetic field strength, the higher the performance you can expect from a degausser. The above is an overview of how degaussers work and what you should consider when looking to buy one.
