You bought a new hard drive and you want to install it, what you should do?

There is one thing called jumper on the hard drive, you need to change its location from Master to Slave if you have the Master, if not live it as master. This is not needed when installing SATA drives.

It is not important if its IDE or SATA drive, the process of installing it is completely the same. You will get some cables that are used to connect the drive to your motherboard, just try to secure a safe place in your tower for the new drive. Also try to avoid touching other cables, circuits and panels in your computer tower. First connect data cable and after that you can connect the power.
