Agree with cmichael138. Since you bought a WD new HDD, go to their website and download Acronis True Image WD Edition for free. Make sure to read the manual - this does a LOT more than just cloning.
The manual is also very handy to help you with "fixing" a default I don't like - your choice. Last time I used one of these cloners, when you get it all set up by default it plans to create on your new HDD a Partition (in which to place the clone copy) of exactly the same size as your old drive. This would leave you with a "new " C: drive the same size as the old, plus a whole bunch of Unallocated Space on the 1.5 TB unit that can be used to create a second (or more) Partition to be used as an additional separate drive. But my choice would be that I'd want ALL of that 1.5 TB new unit to be my (much larger) new C: drive. If that is what you want, too, watch carefully when it presents you with its plan. Don't just agree blindly. Use the menu system (this is where the manual is handy!) to change the planned Partition size to what you want - quite possibly about 1400 GB, which is all the space on the HDD - before letting it proceed.
After you've made the clone on the 1.5 TB unit, this is my suggestion. Disconnect both power and data cables from the old drive, but leave it in its mounting slot. Now take that data cable that is still plugged into your mobo, and plug it into the new 1.5 TB unit. When you boot, it will boot from that new drive because it is connected to the same SATA port that always was used for the boot device. Use your machine for a while. Leave the old drive alone and unused - it is a perfect "backup" of your old system up to the day you cloned. When you are fully satisfied that the new system is working, you can reconnect the old HDD (to a different mobo SATA port), wipe it clean, Partition and Format it, and start using it for something else.
