When you are about to dispose of a laptop, smartphone or other electronic device, how can you safely delete all the personal data?
Some people think that a factory reset will do the job (not always) or they should hit hard disks with a hammer (sometimes not necessary).
The ICO has updated its guidance on how to delete personal data properly from a range of devices, and you can read their advice at https://ico.org.uk/for-the-public/online/deleting-your-data-from-computers-laptops-and-other-devices/.
And perhaps you outsource this to your IT provider or someone else? Well, remember that you are responsible for making sure it’s done properly, regardless of who does it.
