So I just recieved a 250gb Samsung SSD 850 evo. The problem I am having is that I can't get the OS to transfer over and the program that the ssd comes with (data migration) is being pretty screwy. I have about 480 gigs saved on my hdd but the program won't let me choose what to transfer. It does let me choose from only 10 gigs of data to leave out from the cloning process but that isn't even close enough. How can I transfer my OS and other programs (like steam and itunes). I tried clicking and dragging the OS into the ssd file but it wouldn't let me since the file was being used.
