Lol, all this talk about relocators, and wizards...
If your new computer has a master drive in it already, just snap your old one in as a slave and use it.
Of course, if it's your old C-drive, with windows installed on it, that might be a problem. But you could still do it, then transfer that which you wanted to keep to your NEW drive, then reformat the old one and have two drive now.
