There are two techniques that ensure data is irretrievable. These techniques are degaussing of magnetic media and overwriting. Overwriting always ensures that storage devices can be reused. On the other-hand, depending on the type of media, degaussing can render storage devices unusable. Depending on the security need of your organization, we can determine which technique is appropriate for your use case.
Overwriting is generally a lower security standard. However, erasure procedures can be used to make sure that we overwrite full-length, every track, and every bit position several times over. This method always allows for reuse of storage devices.
Degauss is a high level security erase. Degauss guarantees that data is completely erased. However this solution is not always eco-friendly because many devices are unusable once the magnetic layer is destroyed. Below is a breakdown of storage devices that can be reused and ones that are unusable once degaussed.
Regardless of your security requirement, we provide a certificate of data destruction with every order.
