my c drive is a 500gb hdd an is using 322gb in games i just installed a 1 terabyte hardrive
And here we have an issue.
Obviously, you can't squeeze 322GB of stuff into a 120GB drive.
1. Reduce the actual used space on your current drive to below 80GB. Move some stuff off to the new 1TB.
Then a clone operation is possible.
2. Clean install of the OS (and all your applications) on the new 120GB SSD.
