Add a Hard Drive to Your Computer in 8 Steps

Do you own a computer that is more than a year old? If so,
then you may be running out of disk space. In the same way
that closets and attics have a way of filling up and
overflowing, so do hard drives. Maybe your 8-megapixel camera
needs a gigabyte of disk space every time you unload the
camera's memory card. Or your MP3 collection grows by 10
songs every day. Perhaps you are trying to edit videos of the
kids, and every 5 minutes of tape consumes a gigabyte of disk
space. Or maybe you would like to add a TV tuner card to your
machine and turn your computer into a DVR.

Digital cameras, video cameras, MP3 players and TV tuner
cards all consume lots of disk space. If you use any of these
gadgets, chances are that you need more space.

1: Research your machine

Before we start the process of adding a drive, we need to do
a small amount of research inside your machine. The goal of
the research is to find out if it will be easy or not so easy
to add the new hard drive. We also need to find out what kind
of drive you need to buy. You may be able to do this research
by reading through your computer's manuals, but it is far
easier to simply open the case and look inside.

The first question to answer is: How many hard disk drives
have already been installed inside the case? In the majority
of machines, the answer to this question is "one." Having
only one hard disk drive installed makes it easy to install
another one. After you open up your computer's case and look
inside, you will probably find one optical drive (a CD or DVD
drive), a single hard disk drive and perhaps a floppy disk
drive. The optical and floppy drives will be easy to find
because you can see them on the outside of the case. The hard
drive may take a little searching. If you have no idea what
a hard drive looks like, look at the photo above.
If there are already two drives installed inside your case,
then adding a new one is more difficult.

2: Check how much space is available

Is there space available to add another hard-disk drive? Your
current hard disk is probably mounted in a small metal cage
or rack inside the machine. Make sure there is space
available in the cage for another drive. If not, adding
an external drive is an option.

An external drive connects to your computer through either
a USB 2.0 connection or a FireWire connection, so your
computer needs to have USB 2.0 or FireWire connectors. Once
you buy the drive, all you have to do is connect it and fire
up your computer. The drive will come with configuration
instructions, but on Windows XP it will likely be
plug-and-play. You can start saving files on your new drive
immediately.

There is one big advantage to an external drive: you can plug
it into multiple machines and move files around. You can take
it with you anywhere you go. The only real disadvantage is
that it will be slower than an internal drive. If it takes
a minute to copy a gigabyte of data on an internal drive, it
might take two minutes on an external drive. That may or may
not be important depending on what you want to do. For most
applications, the slower speed is irrelevant.

3: See what type of cable system is used

Find out what type of cable system is used to connect drives
to the motherboard. There are two systems in common use: IDE
drives (also known as PATA, or Parallel ATA), and SATA
(Serial ATA) drives. PATA drives have wide, flat cables or
thick cables as wide as your finger, while SATA drives have
thin cables about the diameter of a pencil. You will need to
know whether to buy an IDE or SATA drive, and you should be
able to tell by looking at the cables.

Now that you have confirmed that there is space to install
a new drive in your machine and you know what type of drive
you need (PATA or SATA), you can buy a new drive.

4: Buy a new hard drive

You can buy a new hard drive from many different places:
a retail store, a large computer store, a local computer
parts store or by mail order. Wherever you go to buy it buy
it, keep three things in mind:

* Buy a "normal" 3.5-inch wide hard drive. They're sold
everywhere, but you want to avoid the smaller hard disk
drives made for laptops.
* Make sure the new drive has the correct cable system
(SATA or PATA) to match your machine.
* Make sure the drive is big. Buy the biggest drive you
can afford, because it will probably fill up before you know
it.

Now that you have your new drive, you are ready to install it.

5: Eliminate static electricity

Before we start working with the drive, we need to talk
about static electricity. Your computer is highly sensitive
to static shocks. This means that if you build up static
electricity on your body and a shock passes from your body to
something like a hard drive, that hard drive is dead and you
will have to buy another one.

The way to eliminate static electricity is by grounding
yourself. There are lots of ways to do this, but probably the
easiest way is to wear a grounding bracelet on your wrist.
Then you connect the bracelet to something grounded (like a
copper pipe or the center screw on a wall outlet's face
plate). By connecting yourself to ground, you eliminate the
possibility of static shock. You can get a bracelet for
a few dollars.

6: Set the jumpers

First, set the jumpers (if it is an IDE drive). Let's talk
about this in more detail, because most people have IDE
drives.

In the IDE system, most motherboards allow you to have two
IDE cables. Each cable can connect to two drives. Usually you
use one cable to connect one or two optical drives to your
machine. The other cable is used to connect one or two hard
drives to your machine.

You want both hard drives to be on the same cable. The two
drives on the cable are called "master" and "slave." You want
your existing hard drive (which contains the operating system
and all of your current data) to be the "master" and the new
hard drive to be the "slave." The drive should have
instructions on them that tell you how to set the jumpers for
master and slave. So read the instructions and set the
jumpers. If you are using SATA drives, you do not need to set
jumpers for master and slave because each drive gets its own
cable. Check out How IDE Controllers Work to learn more about
the master and slave configuration.

7: Mount the drive and connect

Now that the jumpers are set correctly, mount the new drive
in your drive cage and screw it into place.

Next, plug in the drive's power connector to the power
supply. If it fits, then it's a match.

Connect the IDE or SATA cable to the drive.

8: Format the new drive

Close the machine, power it up and configure your new drive
using the Windows XP drive administration tool. To do this,
click the Start button, open the Control Panel, Switch to
Classic View, click on Administrative Tools, click on
Computer Management, click on Disk Management.

Look at the graphical area in the bottom right of this
display. Disk 0 is your original hard drive. Disk 1 is the
new hard drive. Chances are that the new drive will not be
initialized , or formatted. Click the small button to
initialize the drive, and then format it as an NTFS volume
(right click on the new drive, then click “Format...”).
Formatting may take an hour or more, so be patient.

When the formatting is done, you are ready to use your new
drive.
