How to Wipe a Hard Drive

When you delete the files on a hard drive, they aren’t actually gone–not until those old files are overwritten by new data. This means that anyone who gets hold of the drive will have access to all of your files. Below, we’ll explain how to wipe your hard drive on Windows and Mac computers for good. And once your drives are like new again, download Clario AntiSpy to protect them from spying eyes.
