when I start the SDOCK2U313R it makes the partition for the new drive then faults out with a signature collision
Hello @Mike and thank you for your interest in our Community.
Getting a signature collision error usually happens when you are trying to load two drives which have already been cloned in Windows. Once your drives have been cloned, you can use one (or swap their positions) depending on what the cloning intention was.
If this is not the case, please provide some more information about the steps you’ve taken and context of where and how you get this error.
I look forward to hearing back from you!
