Things You Should Know About Hard Drive Degaussing Lots of PC users believe that when one deletes a file and empties the trash bin, the information is completely erased. But that is further from the truth. Fact is that the data is still in the drive. In fact, all one does when they delete such information from their computer is to erase the path that one can use to access the information. Nonetheless, one can still be able to erase info completely from their hard drive. One can erase data from their computer hard drive in three different ways. You can use a hard drive eraser, you can physically destroy the drive and finally, you can degauss the hard drive. Degaussing means doing away with data completely. Degaussing is very popular considering the amount of sensitive information the needs to be permanently erased by various organizations. This method of doing away with data is different from others. Unlike deleting and formatting, degaussing completely clears information by the use of a special technique. Here are some things you need to know about degaussing of a hard drive. Uses Magnetic Fields

Degaussing is essentially the procedure by which a magnetic field is eliminated or decreases. This means it requires magnetic fields in order to erase information from magnetic storage devices such as discs and tapes. A fine coating of chromium oxide and iron oxide sometimes exists on the tape. During the process of degaussing, a very intense magnetic field is generated. The magnetic memory stored on either the chromium oxide or the iron oxide is done away with completely because of the immense power of the magnetic field produced. The data stored on a disc is therefore destroyed completely because the magnetic field of the tape is changed. previously recorded data is either removed or randomized during degaussing. This makes it impossible to recover the data.

Safety Concerns As per the WHO degaussing is completely harmless to people’s health. This is particularly with regard to one’s exposure to the magnetic fields during the process. Speed of the Degaussing Process Degaussing might sound like a slow and complex process. Nonetheless, contrary to what the name may sound like, this process is actually easy and fast. 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. On the other hand, the so-called drive erasers simply overwrite the existing data making it impossible to forensically restore or decipher. Unlike the name suggests, there is no type of erasing that goes on when using HD erasers.
