After reformatting my computer and reinstalling all I needed I am noticing some odd issues. For one some of my old programs/games that were not in the program files folder were still on my system and 2 after only installing 55 gigs of data on my 500 gigabyte hard-drive I only have 120 gigabytes available for use. Why is this? What's going on and did I do something wrong? Is there another method I should use to reformat other then just putting my CD in and restarting to enable the process and choosing the default options?
