When mirroring the current HDD to the new SSD must they be the same capacity? I have a 1TB HDD with the OS and program files and they only take up 145GB. I'd like to clone or rmirror that to a 480GB SSD and make that the boot drive and then reformat the 1TB HDD to use as storage and make that an E: or F: drive. Is there a free software that will accomplish what I'm trying to do? Thank you in advance.
