Difficulty: Moderately Easy
Step1
Set up your external hard drive according to its instructions. The two major steps in setting one up are connecting it to your computer and plugging it into an external power source.
Step2
Install any drivers that came with your drive so your operating system will recognize it. If the drivers are outdated, download and install new ones from the manufacturer's website.
Step3
Open the "My Computer" panel. You'll see both your regular hard drive (the C: drive) and the external hard drive listed.
Step4
Double-click the external hard drive's icon to open its window.
Step5
Drag and drop any files you wish to copy to the external drive into this window.
Step6
Right-click the "Safely Remove Hardware" icon in the System Tray and eject the drive once you've finished copying your files.
Step7
Power down your external hard drive to avoid long-term damage.
