An external hard drive is similar to the internal hard drive inside your computer, the difference being that it is mounted in it's own enclosure. It is an extremely useful device and can easily connect to your personal computer using a USB or firewire cable. The main reason people choose to buy these devices is to ensure they have a safe back up of all the data that is on their computer or to store files that are too large to store on your personal computer.
Once connected, your computer will recognize the equipment drive as a storage device and you will be able to access it as you would with any other internal hard drive.
If you are travelling external hard drives are very useful for taking data with you. Should you want to take large files and data from the office to your house then such a device is invaluable. Some data files which are large and would take up too much space on your computer, such as photos, movies and music, can be stored on such external hard drives.
While surfing the internet your computer may be exposed to certain viruses which can damage and delete data stored on it. When you access the internet you can leave your external storage device safely disconnected. Family and friends too who regularly use your computer may introduce viruses or even accidentally delete or damage files. For these reasons many people feel safer having a back up of all their data on an separate device. This way, even if all files and folders are damaged or even deleted you can simply copy them from your hard drive back on to your main computer.
