HDD wont show

[Defectspecsmaybe]

Hello my friends,
Build my first computer, and only 1 of my discs is showing.
that's the SSD which I installed W10 on, the HDD won't show, but it was available in BIOS, so the computer register it.

Go to Disk Management to find it... If you see it... it probably needs to be assigned a Drive Letter.

Hi there Defectspecsmaybe,

If we assume that you've connected the drive properly, you should go to Disk Management as SBMfromLA suggested.
After that, you need to initialize -> partition & format the drive.
