Data Destruction Series

Data destruction methods can be divided into soft destruction and hard destruction. Soft destruction is also called logical destruction, which means data destruction or data erasure through software methods such as data overwriting. The hard destruction of hard disk data destruction uses physical and chemical methods to directly destroy the storage medium to achieve the purpose of thorough hard disk data destruction/data erasure. When degaussing, you can only delete the directory and restore the data. Physical damage through the shredder is a safe method for permanent destruction to prevent data leakage.
