The issue, if I am reading it correctly, is that he has 2 identical drives. The problem is knowing which one is the OS drive and which is the data drive. You cannot know which is the proper physical device from free space.yup that's my point he can just look at how much space is used on his c drive then that will tell him what drive is his os drive in the cloning software unless I am missing. Or his cloning software doesn't tell used space. or just use disk management. maybe I am just missing something lol
i.e. (Made up)
SATA Port 2 => 512GB Crucial M500 SN1234
SATA Port 1 => 512GB Crucial M500 SN4567
Which port is the OS drive connected to? Maybe its 1, or maybe 1 was added after and the first port was easier to reach.
