On Systems: My Experience Explained

Useful Guide on How To Degauss A Hard Drive Destroying data has always been a necessary and sometimes legal requirement of many industries. Proper destruction of sensitive data safeguards the security of an organization and its clients. Due to the advancements in data storage technology, new ways of destroying digital data have been invented. Degaussing is one of those ways in which you can erase data on a hard drive. If you are considering this option, here are the main things you need to know. To begin with, here is a brief description of how degaussing works. Desaussing is a way of permanently erasing data stored in most electronic media. The degaussing process can be accomplished by using a machine known as a degausser. Data storage on a hard drive works by coding information on a magnetic strip in the drive. A degaussing machine will normally create a strong electromagnetic field that destroys the ways information was stored and thus erase it. Degaussing results are usually permanent, meaning that data is permanently unreadable. For the best results during degaussing, you need to learn what type of media you are dealing with. Depending on a drive’s coercivity rating, only certain degaussing machines will be effective. Hard drives with higher coercivity can only be successfully erased with a degausser with corresponding power. Consult experts and read widely about such ratings so as to get the most effective machine for your needs.

Other than the strength of their magnetic field, degaussers are also differentiated using other criteria. 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. You can even buy a portable degausser that you can comfortably move from once branch to another. There are even government approved degaussers that are recommended due to their effectiveness.
The Ultimate Guide to Computers
Destroying data with a degausser is very simple once you have the machine. Ensure that every drive you want erased goes through the machine for good results.. Some degaussers are so powerful such that they also destroy the hard drive itself. Use a degausser if you are also willing to lose the hard drive. A degaussed hard drive is only useful for recycling and there are companies that purchase them. 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. Most of these companies can destroy the data at your premises or you can go to them. Such companies will handle any volume of hard drives and they will also sell the shells on your behalf.
