HDD appears in BIOS, but not in disk management.

So, I bought a new hard drive, 5TB Toshiba internal 3.5" HDD. I have it all plugged in, power and SATA, and plugged into my motherboard in the SATA port. When I boot into the BIOS, can see under the storage section that it us plugged in and ready to be formatted. However, whenever I go to the disk management, the only drive showing up is my 2TB Seagate drive that I installed my OS. No other drive is displayed with the unallocated space.

EDIT:

Windows 8.1

ASRock Z97 Extreme 4

650W PSU

Sapphire R9 290 Vapor-X OC

8GB RAM

Not sure if any besides the first two is actually useful.
