I'm buying a 250GB SSD and was wondering if I needed to format my HDD as it has Windows in it. There is no reason to keep Windows on my HDD obviously, but I was wondering if there is any danger connecting an HDD with Windows to an already-running-windows SSD. I'm afraid all the junk from my HDD's Windows will start loading up (registry files, auto start programs and fuck it up) Sorry if this sounds silly, my first time with SSDs.
