Hard Drive Destruction

Many people believe Hard Drive Destruction is a means of Data Destruction however; unfortunately it isn't as the data is still physically present on the Hard Drive fragments. The Standards require you to Destroy your Data independently of the Hard Drive, in fact in many cases you don't have to result to Hard Drive Destruction; destroying the data itself is all that’s required!

The impacts of our actions on the Environment should also be considered when you are investigating Hard Drive Destruction; this area is regulated by the WEEE Legislation, (Waste Electronic & Electrical Equipment) which addresses how you dispose of WEEE and reducing the amount of WEEE produced. Physical Hard Drive Destruction reduces a perfectly useable item into scrap, increasing the amount of WEEE produced by your Organisation thus affecting your Carbon Footprint.

Should your Data Classifications and Risk Assessments prohibit re-use then you should employ a method of Data Destruction prior to the physical Hard Drive Destruction, depending on the type Hard Drive you should use one of the following Data Destruction methods.

  • Hard Drive Overwriting
  • Hard Drive Degaussing

Both of the above methods must use CESG approved devices and follow approved methods, data destruction should be performed onsite allowing the Data Controller the ability to supervise and sample the data destruction. Once the data is destroyed and certificated, the Hard Drives can be contained and removed for disintegration, this can be performed offsite – onsite data destruction shred hard drives down to 6mm which is the smallest shred available which still allows the fragments to be divided into composite materials ready for recycling, this supports our 0% Landfill Policy.
