Over time, we accumulate hard drives, computers, cell phones, and other data storing devices, most of which carry our personal and private information.
In fact, you probably have an old bin or drawer housing those devices right now.
Unfortunately, you can’t get rid of them without taking the proper precautions to make sure your private data is secured. Physical destruction is one form of ensuring your private files aren’t exposed.
However, you shouldn’t physically destroy magnetic forms of media by burning them. By doing this, you are emitting toxins into the air. This form of media should also not be buried because it’s not biodegradable.
Luckily, magnetic degaussing can give you peace of mind in knowing your files will be erased forever. The question remains: is it safe to do in-house degaussing?
Degaussing is a form of overwriting secure data and erasing it without having to worry about that information falling into the wrong hands. In some cases, someone might choose to physically destroy a hard drive. On the other end, degaussing doesn't physically destroy the hard drive, but demagnetizes or neutralizes the magnetic field used for data storage. The data storage can be any form of magnetic media such as hard drives, floppy disks, etc.
Simply overwriting or deleting a file isn’t enough. With the use of a degausser, any magnetic media can pass through a powerful and controlled magnetic field. During this process, the degausser rearranges the magnetic particles within the device and, once completed, no previously recorded data will be recognizable.
In order for a 100% data erasure to occur, the degaussing coils need to be two to three times the energy rating of the device being sanitized. The more intense the degausser’s magnet, the greater the likelihood of achieving secure data destruction within seconds. If this is not accomplished, fragments of data will remain.
Of course, shredding is an added redundancy to ensure absolute secure data destruction but you shouldn’t choose to do one over the other.
When it comes to the process of shredding, this solution only physically alters the device. It is important to recognize that data is still recoverable from shredded disk fragments.
In order to meet the National Security Agency’s (NSA) requirements of data destruction, the first step is to degauss a device, followed by shredding it to 2mm particle size, the same thickness as pencil lead.
Magnetic degaussing does not work on SSDs, cell phones, laptops, and tablets. These devices use an electric charge to store data. Degaussing these forms of media would have virtually no effect on the device since the information is not magnetically compiled.
To sanitize an SSD, you are left with two options.
Absolutely, in-house degaussing is safe and is definitely safer than physical destruction. But as we outlined above, you have to take inventory of your current ITAD situation and create exceptions for devices that cannot be degaussed. With that knowledge, you'll have to consider:
