I have a drive partitioned into C and D. C is the boot drive. The whole drive is 1T. The C drive is 303 gb. I need to migrate the boot drive (C) to a 320 gb drive. Can I do this, or will it try to also copy the D drive? Hope I have made that clear. If it is possible, I will then try to migrate the D drive to another 1T drive. Many thanks for any help.
