Hey guys, I just finished my first PC build. Everything seems fine, but my 2TB secondary SSD is missing in 'This PC'. It shows up in the BIOS and Device Manager, but it just...disappeared in Windows. I read somewhere that I need to use diskpart to 'initialize' it or something? Is that safe? I'm terrified of accidentally wiping my OS drive. Could use a step-by-step for a total noob. Thanks!
