Things You Should Know 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. This however is not 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. You can actually erase data from your computer using three different techniques. You can erase the hard drive using a hard drive eraser, you can physically destroy the drive, or you can do what is known as degaussing. Degaussing 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 is unique compared to other methods. Degaussing is not like simple deleting or formatting, it uses a unique technique to clear data completely. Below are some fact s you should know about hard drive degaussing. Uses Magnetic Fields

Elimination or decrease of a magnetic field is what is termed as degaussing. This means it requires magnetic fields in order to erase information from magnetic storage devices such as discs and tapes. 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. The immense power of this magnetic field is what aids in the permanent removal of the magnetic memory from the chromium oxide or the iron oxide coating. The change in the magnetic field is what does away with the data on the drive. During this process, the recorded data pattern is either removed or randomized. This makes it impossible to recover the data.

Safety Concerns According the World Health Organization, there is no evidence that suggests any kind of harm can come from this type data destruction. This is particularly with regard to one’s exposure to the magnetic fields during the process. The Speed of The Process Degaussing might sound like a slow and complex process. However, unlike the phonetics might insinuate, the data destruction process is one that is quite simple and quick. Uses a Different Concept from Hard Drive Erasers As aforementioned, degaussing, works with the help of a magnetic field to reset the hard drive’s magnetic charge to a state that is neutral. Conversely drive erasing is where data that is on a drive is overwritten so many times that it becomes impossible to access decipher or restore forensically. Essentially, no erasing actually goes on in this process.
