I want to destroy data
Those rumours were true – computers cannot delete data. Information previously deleted on your computer, USB or SD card by using the standard delete > empty bin method, can be recovered. In order to destroy data you need to overwrite its physical location on the disk with new information. Specific tools exist for this purpose including Bleachbit for Windows and Linux, as well as CCleaner and Eraser for Windows. MacOS users can follow the techniques mentioned in this guide or recommendations regarding SecureTrash on the Apple website.
