Fitting your second hard disk
1Configure the jumpers
Now, you need to configure the drives as 'master' and 'slave'.
The master will take priority over the slave in the event that they are both trying to access the same resources such as your computer's processor; your new drive MUST be set as the slave.
To set the drives' status you need to adjust the jumper - small pieces of plastic that slide over the drive's pins.
The new drive's manual will have instructions on how to do this.
2Insert the drive
Connect the data and power cables to your new drive and slide your drive into the spare slot inside your PC using the supplied bracket.
Secure with screws.
3Restart your computer
Now, restart your computer. Go to Start > My Computer.
Your original hard disk drive should be marked 'C'.
You should see an icon for your new drive marked with another letter ('D', 'E' or 'F', say).
If you can't see this icon check that your cable is connected to your computer's motherboard as well as to your new drive.
4Format your drive
Use the installation software that came with your drive to prepare (format) your new hard disk drive.
Once you've done this your drive will be ready to use.
If the software asks you to choose between formatting your drives as NTFS or FAT32, choose NTFS.
