Is it time for you to get a new computer, tablet or smartphone? If so, you're probably going to sell or give away your old one.

That means almost anyone with a little know-how can recover it with a simple and free program. The only way to completely secure your gadget is to wipe its hard drive.
With that in mind, we're going to tell you how to wipe the data from Android and Apple gadgets as well as PCs and Macs.
