No. Simply deleting files or performing a standard reformat should not normally be treated as secure data destruction. Those actions may remove files from ordinary view or recreate the drive’s file system, but they do not necessarily ensure that the underlying information can no longer be recovered. The National Cyber Security Centre states clearly that…

Yes. A damaged SSD can still contain recoverable information even when the device no longer works normally. The key distinction is between device failure and data sanitisation. An SSD may stop appearing in a computer, fail to boot, suffer damage to its controller or become physically damaged while some of the underlying flash memory still…

Approving a data destruction process should involve more than checking whether a supplier promises to “securely destroy” old IT equipment. Compliance teams need to understand what is being destroyed, which destruction method will be used, how assets remain protected before processing, who is responsible at each stage and what evidence will demonstrate that the process…

Chain of custody in secure data destruction is the documented record of who controlled data-bearing assets, where those assets were held and when responsibility passed from one person, team or organisation to another. Its purpose is to prevent gaps in accountability. A hard drive may eventually be shredded, degaussed or otherwise securely sanitised, but the…

There is no single magnetic-field strength that automatically makes a degausser suitable for every hard drive. The important relationship is between the magnetic field produced by the degausser and the coercivity of the magnetic media being processed. The degausser must be sufficiently powerful for the particular media and recording technology involved. This matters because modern…

When an organisation sends 100 hard drives for secure destruction, knowing that 100 drives were destroyed is useful. Knowing which 100 drives were destroyed provides a much stronger level of traceability. That is where asset serial numbers become important. Recording an individual manufacturer’s serial number or another unique asset identifier allows a destruction record to…

Yes, hard drive destruction can be carried out at your organisation’s premises using specialist mobile equipment and a controlled on-site process. On-site hard drive destruction allows data-bearing assets to remain within the organisation’s location until they have been physically destroyed. This can be particularly valuable for businesses that handle sensitive, confidential or regulated information and…

A solid-state media shredder can destroy a wide range of devices that store data electronically in flash memory. These may include solid-state drives, USB flash drives, memory cards, small storage modules and some data-bearing circuit boards. However, suitability depends on the shredder’s design, input dimensions and output particle size. A machine designed for standard 2.5-inch…

After hard drive shredding, the remaining materials are collected, secured and prepared for specialist recycling or material recovery. A shredded hard drive does not simply become general waste. It is broken into a mixture of metal, plastic, circuit-board material and other components that must be handled carefully. The first priority is data security. The second…
