An external hard drive can act as insurance if the internal drive in your PC fails, allowing you to back up your important files, data and multimedia content. An external hard drive typically provides more storage than a flash drive, and it can store a larger number or files. When you connect the device to your PC for the first time, Windows will install the necessary device drivers. You can then use Windows Explorer to copy and back up your data.
Plug the micro-USB end of the cable into the external hard drive; then plug the larger end of the USB cable into an open port on the PC. If the external drive has an AC adapter, plug the adapter into a nearby power source before connecting the device to the computer.
