Need hard Drive help

[kogo50]

I have a 320GB hard drive in my PC currently and I look to see how much space I have left and I only have 20GB left. So I think i'm going to get a second hard drive but I have a few question. I only need the hard drive for extra space and need to know what I have to do to set it up? Will one be the main hard drive and will one be secondary or will it act like I put a bigger hard drive in it? I need to know what its going to do.

there will be two separate drives you can move data to the new drive or install programs on it but you can not move a program without reistalling

My comp
C:\ os and programs
D:\ my files

You can add the new HDD, and mapped the new aplications an documents to the new HDD.
