SO I am sitting here with a new Samsung 840 EVO (not connected yet, only out of the box) I am running windows 7 64 bit. I have two old HDDs 500 gigs each. one is C drive and the other is D. I don't really care for any of the information on either except for my windows license. I really do not want to purchase another one just to have all three of my drives completely clean. so my question is what is the best way to go about accomplishing a clean wipe of C and D and moving the OS on to the new SSD. also I don't have the special sata to usb connector.
