Data destruction is an exercise that has been around for quite a while now. Proper destruction of sensitive data safeguards the security of an organization and its clients. While paper shredders and incinerators where useful in the past, new technology is now needed. Data degaussing is one of those ways that is effective for destroying data on a hard drive. If you are considering this option, here are the main things you need to know.
The first important part is to know the meaning of degaussing. It is a way of destroying electronic data stored in common computer hardware. A degausser is a machine that is especially designed to do the actual data degaussing. Data storage on a hard drive works by coding information on a magnetic strip in the drive. A drive degausser creates a strong magnetic field that disrupts that pattern and thereby destroys the information. Degaussing results are usually permanent, meaning that data is permanently unreadable.
To achieve the desired results during degaussing, you need to know the media you are dealing with. The ability of a hard drive to be degaussed by a certain machine will depend on its coercivity. The general rule is that; the higher the coercivity of a hard drive, the stronger the degausser required. This is to say that you have to be careful when purchasing a degaussing machine.

Degaussers also differ in many other ways other than the strength of the electromagnetic they generate. Some machines generate the magnetic field by using electricity while some use earth magnets. Others are also designed to handle large volumes of hard drives while others for fewer hard drives. If you need to do drive degaussing at different locations, you can buy a portable degausser. In order to get the best, go for the government approved degaussers that have been tried and tested.

Once you have the machine, the instruction are quite simple. The process normally involves passing through all the hard drives on the plugged in drive degausser.. The degaussing process can also render the hard drive unusable again on top of erasing current data. When you use a drive degausser, be ready to lose both the data and the hard drive itself. If you are wondering what to do with a degaussed hard drive, you can sell it to recyclers who retrieve useful parts.
If your type of business requires you to regularly destroy a lot of data, buying a degausser is a good option. The others can hire the services of professional degaussing companies. Such services are always flexible, meaning the professionals can come to you or you can take the drives to them. Such companies will not only destroy the data, they will also get rid of the hard drives for you.
