Here is a list of steps you can take to securely dispose of old electronic devices and protect your data:

1. Back-up your data on a secure cloud-based server or an external storage device.
2. Remove all personal information from your device.
3. Factory reset your device, which will erase the hard drive and restore the settings to factory defaults.
4. Physically destroy the hard drive – using a hammer, drill, or degausser.
5. Recycle your device.
