Seagate SSHD not recognized

I just built a new computer. I couldn't decide if I wanted an ssd for the speed or a mechanical drive for the storage. I got both. The drive is recognized in the windows installation setup, but is not recognized in the bios. I tried ahci mode and ide mode. Nothing works. Do I need to update the bios? Do I need to send it back to newegg? I tested all the sata ports with an 80gb seagate mechanical hard drive. Any help is welcome and appreciated so thanks in advance.

p.s. My motherboard is the asus m5a97 r2.0.

I updated the bios and changed it from ahci to ide. It still doesn't recognize the drive. What's worse is when I had it plugged in the pc kept blue screening. There is obviously no fix for this and I need to send it back.
