Keep your personal data off the market

摘要

The hard drives which remain a serious data security concerns are discussed. Various steps can be taken to ensure that the average individual who is buying one's used equipment can't access the old files. To ensure that one's data is removed beyond anyone's practical ability to recover it, one must remove or scramble the data itself, not just the marker that points to it. These tools overwrite every sector of the hard drive with binary ones and zeros, and those that meet government security standards overwrite each sector multiple times for added protection. Removable storage devices such as SD cards can be plugged into a computer and wiped by the same utilities that work for computers and hard drives. Some firms ensure physical destruction by using a product like the Guardian Physical Drive Destroyer.
