What You Should Know About Hard Drive Degaussers 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 produce a strong magnetic field. The data on a storage device gets erased when the device comes in the magnetic field of the degausser. When you erase the data on a hard disk using the PC, the data is not completely wiped off. The data that is deleted is usually stored on a compartment of the hard disk that can be accessed through different recovery processes. If you want to be sure of completely wiping off the data on your hard drive, you should degausse it. This explains why government institutions and corporations usually use degaussing to erase date on their drives. How a Degausser Erases Data If you want to know how degaussing works, you should understand the way data is stored on a hard drive. Generally, hard drives have a magnetic strip where data is stored on. 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.
Technology – Getting Started & Next Steps
The magnetic strip of a hard disk is destroyed when the storage device is introduced into the magnetic field of the degausser. When a hard disk is brought into the magnetic field of a Degausser, its magnetism will be destroyed and the data randomized. This makes it impossible for the data to be recovered when the hard disk has been put next to a Degausser.
How I Became An Expert on Resources
Which Degausser Should You Buy? There are various types of degaussers in the market. It is important to carry out research prior to buying a degausser. You should research well to find the right degausser for your needs. Among the most common degaussers are the electromagnetic type. The degaussers charge a degaussing coil to produce a magnetic field. Permanent magnetic degaussers are the other common option you can choose. You can operate these degaussers without electricity since they usually have a rare earth magnetic. Degaussers may also be built for specific activities. 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. Generally, the performance of a degausser is mainly determined by its maximum magnetic field strength. 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.
