We’ve covered securely erasing internal memory devices in-depth before, but in this post, we’ll be delving into how to tackle external devices. It’s a good idea to make sure you know how to securely erase external devices, like hard drives, SD cards, flash drives, or whatever else needs to be wiped.

In any of these cases, you might need to ensure that sensitive data is completely wiped and cannot be recovered by any means. Need to free up space on an external storage device, or you want to get rid of some sensitive information? Perhaps you’re disposing of a device, selling it, or simply loaning it out.
