Secure Hard Drive and Data Destruction

In an increasingly digital world more and more data is being stored “in the cloud”. And for good reason: hard drives aren’t invulnerable and often fail. Hard drives contain delicate moving parts that are easily damaged from drops, overheating and humidity.

If your hard drive fails you might think it’s “dead” but in fact, it still contains valuable personal data that can be accessed by others. Re-formatting, erasing, wiping or tossing the hard drive into landfill is not ideal because you are risking revealing personal and business data.

What is Hard Drive Degaussing? And Why is it not Enough to Degauss your Hard Drive?

Hard drive degaussing is the process of permanently eliminating stored data on any type of ‘magnetic’ media, this includes hard drives, video tape, data reels or old style cassette tapes.

Inside your hard drive is a circular metal disk that has a fine coating of chromium dioxide or iron oxide. This disk is what your hard drive ‘writes’ on when recording data. If you open up a hard drive casing you would see a shiny metal disk with a series of fine lines, which make up the recording or data.

Typically, a degaussing machine permanently destroys all data on your hard drive disk by creating a strong magnetic field that erases or randomises the recorded data thereby destroying it. However, degaussing is not a foolproof or complete solution and doesn’t always work. That’s we always recommend the complete shredding and full physical destruction of the hard drive so that its material can also be destroyed and recycled.

Thanks to Alex and the team at Corporate Document Destruction for their excellent and efficient service. We have a home office and had accumulated a few plastic tubs of documents that were too sensitive and personal to be thrown in the recycle bin. After talking with Alex he organised a bin to be delivered, the driver helped us load all our documents into the secure bin and took it right away. I never realised this would be so easy.
