Question ASRock z370 killer SLI/ac 2nd m.2 SSD problems

[Swhitlock]

FIrstly, my set up:
CPU: i5 8600k
GPU: GTX 1070 ti, 8gig
RAM: 2, 8 gig ddr4 3k mhz
Storage: 512 gig m2 SSD
Motherboard: ASRock z370 Killer SLI/ac
Powersupply: evga 850 supernova
Monitors: Main, Benq 144, Secondary Benq 99, and a 55 inch samsung 4k

So about 2 weeks ago I bought a new SSD. Its a WD Blue 3D NANO SATA SSD m.2 2280 1TB. Whenever I put it in my 2nd m.2 slot on my motherboard (the one below the first video card slot) and booted the computer I went straight into the bios to make sure it was being recognized and it is no problem. Whenever I get into windows though and goto my pc it is only showing my 512 GB SSD and not the 1TB. Am I doing something wrong? Is the slot faulty? Is the SSD not compatible with the slot? I am not the most computer literate person but I can google and read with the best of them. Any suggestions?

You may have to go to disk management in windows, maybe format the disk and assign a drive letter.

Try converting it to mbr in Disk management.
