What is an External Hard Drive?
A Hard Drive is a component every computer needs to store at least it operating system in order to function, and then save every file. There are many problems resulted from situations such as the storage of large files, and the existence of viruses, that affect hard drives and therefore the functionality of any computer. An external hard drive, it is a good way to prevent this problems.
An external hard driver is a device outside the computer; they are portable and usually larger than the internal hard drive. These devices are connected to the computer through a high-speed interface cable, a USB or a Firewire (Most Common Types).
I use the computer and save a lot of important information every day and unfortunately it took me 2 painful losses of information, and many looses of time to realize that I needed an external hard drive to store safely my information and stop saturating my internal hard drive with large files. Besides security advantages, I find external hard drives very convenient also because I just plug in and out the driver in one computer or the another, Mac or PC and work on the files I was working the day before. Sometimes instead of carrying the computer around I just carry my small hard drive and connect it to any computer when I need to open any file.
On this link there is a list from best buy of external hard drives:

I highly recommend all Western Digital products because I have two of those and I have never had any problem with them.
How a Hard Drives get Broken?
A Hard Drive is usually broken when the read-write head or the platters are contaminated and the head scrapes the platter surface, this is usually called “Head Crash” and causes data loss. Head crashes are caused by electronic failure, sudden power failure, physical shock, wear and tear, corrosions, or poorly manufactured platters and head.
Also, a hard drive relies on air pressure to spin; it requires a certain range of air pressures in order to operate properly. If the air pressure is too low the there is not enough lift for the flying head, so the head gets too close to the disk, and there is a risk of head crashes and data loss. It is important not to cover the breathing holes of it and not to expose it to high humidity for extended periods because head and platters could corrode.
