I have a problem with my 2012 Macbook Pro, I'm trying to install a new WD Black 750 GB SATA III 7200 RPM in it. The problem is when I try to reinstall OS X Mountain Lion, it didn't find the drive I just installed. When I try to erase all the data from it and turn it into an OS X extended file format, Disk Utility returns an error saying that it couldn't format it. I'm really stuck right here, has anyone else encountered the same problem and know how to resolve or get around it? Any answer will be much appreciated. Thank you.
