SAMSUNG EVO 500GB install on Dell XPS 8700 special edition desktop

Here's an issue I'm trying to resolve: Just purchased dell XPS 8700 special edition desktop with 16GB RAM, 2TB HDD, 30GB MSATA, Windows 8.1. My intention is to use a newly purchased SAMSUNG EVO 500GB SSD as boot drive and the original 2TB for storage (I do photography). Well, I got a USB 3.0 16GB flash drive and made a system restore backup. I connected the SSD as secondary drive (connected to SATA2.....original  2TB is on SATA0, DVD drive is on SATA1). I successfully cloned the 69GB (OS, applications) from the original 2TB onto the 500GB SSD. I shutdown the computer, disconnected the original 2TB (unplugged the cables) and booted up successfully from the SSD drive. Prior to first boot, I accessed the BIOS and changed the SATA operation from "RAID" to "AHCI".  I also connected the Samsung SSD to SATA 0. The OS and apps are running well. I shutdown the computer, reconnected the 2TB HDD to SATA 2 and restarted computer. I can see this 2TB HDD drive on the BIOS but not in windows. An Intel Rapid Technology popup displays a status of "Incompatible" and usage "Unknown" on both the 2TB HDD and 30GB MSATA. I really need help getting the 2TB recognized for storage of photo shoot.

thanks
