Seagate Backup Plus Fast 4TB External Drive

[sicksix]

I have a Seagate Backup Plus Fast 4TB External Drive which is basically 2TB drives with a raid 0 controller inside the casing. The Micro-B USB 3.0 port attached to the drive became damaged so I took the casing apart. The raid 0 controller could not be replaced, so I had Seagate send me a replacement drive under warranty. Odd thing considering I told the guy I was going to take it apart and use the new raid 0 controller on my old drives and send back the broken pieces. When I plugged the new controller into the drives, it sees the drive as an unformatted drive. I have quite a bit of information on the drives so I need some assistance on finding out what I can do to get this adapter configured to read my information. I was not sure if the controller had configuration files on it or if it is just a basic controller. Any ideas?

The controller should be basic.
Is it certain that the drives have gone back inside in the exact position as they were in the old failed casing?

The two 2TB drives are connected via a metal rail on the sides to sort of pancake them together. The actual raid controller can be flipped one way or the other. Meaning the raid controller is female and the drives are male and the way that the controller is setup, you can rotate it one way or the other like plugging in a lightning cable, doesn't matter which way you plug it in but I assume with this controller, there is a correct way but either way I flip it, it doesn't work.

I am familiar with those controllers.
The drives have to go back in the exact same position they were. There is a "drive order" that has to be preserved, as the drives are likely set as a RAID 0. Hopefully, you marked them with "top drive" and "bottom drive" or something similar.
