Have a Samsung 850 Pro 256gb on the way and when it gets here I will be cloning from a Vertex 3 120gb with Windows 7 on it. I will be using Macrium Reflect. I have cloned a few drives but never a C drive. After searching around I read that it is best to unhide all of the hidden files in Windows before cloning an operating system drive. I always keep mine unhidden so that is not an issue. Any other nuances I should know about? Any other cloning program suggestions? Have had good luck with Reflect. And does Windows 7 have any kind of hissy fit when you unplug one drive and plug in a new one with windows on it. Oh.....on a C drive when you clone will it write the C drive letter to the drive so it will just boot up once the original is disconnected? Any info would be good.
