What One Should Understand About Hard Drive Degaussing
A lot of people think that once a file is deleted to the trash bin and the bin is emptied the info disappears completely. But that is further from the truth. The reality is that the data is still in the hard drive. The only thing one achieves is to delete the pathway to the files in the PC. However, it is actually possible to erase data from your computer hard drive. There are actually three different ways to erase data from a computer hard drive. You can use a hard drive eraser, you can physically destroy the drive and finally, you can degauss the hard drive.
Degaussing at www.drivedegausser.com means doing away with data completely. There are so many different organizations dealing with sensitive information that employ degaussing machines for this type of work. This method of erasing is unlike any other method of erasing data. Unlike deleting and formatting, degaussing completely clears information by the use of a special technique. Discussed below are some important things to understand what degaussing is all about.
makes Use of Magnetic Fields
Degaussing is essentially the procedure by which a magnetic field is eliminated or decreases. In order to erase data from magnetic storage devices, there has to be a magnetic field involved. Magnetic storage devices have very fine coatings of iron oxide as well as chromium oxide that sit on the tape. During this degaussing process an intense magnetic field is generated. It is the intensity of this magnetic field that aids in permanent removal of the information stored on the iron oxide coating or the chromium oxide. The data stored on a disc is therefore destroyed completely because the magnetic field of the tape is changed. Data that was recorded is usually randomized or completely removed making during this process. This makes it impossible to recover the data.For further details regarding hard drive degaussing, check out https://www.youtube.com/watch?v=jvwXGaVNchQ.
Degaussing does not cause any harm to people's health according to the World Health Organization. This means people shouldn't fear being exposed to these magnetic fields during the degaussing process.
How Fast It is
Degaussing might sound like a slow and complex process. However, contrary to what the name sounds like the process of erasing data is quick and simple.
Works Differently From Hard Drive Erasers
As already highlighted degaussing uses the help of a magnetic field to neutralize the magnetic charge in a drive. Portable degausser however, actually work on the principle of overwritten data, once the data is overwritten enough times it becomes impossible to forensically recover it or even decipher its meaning. Unlike the name suggests, there is no type of erasing that goes on when using HD erasers.
