WD is a good co. to get suppoprt. Visit the support website and using your HD model# enter or locate it. There you will find or links to the s/w you require. I believe its called LifeGuard or similar, though it maybe Acronis. If you're registered then getting al that shouldn't be a problem. I suggest you find your product and usually within the webpage is the s/w required. Also, any docs" that can help or download. You can then read what is required or follow instrictions. Also, don't do this unitl well informed. It seems hard but it really isn't. I also suggest if you haven't yet install the new HD on the next SATA port, if your current active HD is probably on SAT 0 or 1, thus the very next port is available, provided the CD/DVD drive isn't there, if it is move it to behind the new SATA HD port, like SATA 3. I think you get the idea. Hope this all helps.
