I'm upgrading my computer and replacing my current 80gb D drive with a 250gb drive. I don't have an external, so what would be the easiest way to transfer everything over? Also, all of my system programs are on my C Drive so I won't have to reinstall everything correct? Will programs like photoshop and certain games on my D Drive still be runnable after I transfer to the new HD? Like will it create a mirror or will I have to reinstall stuff. Thanks a bunch.
