How can I tell whether a program is on my HDD or my SDD (Windows 10?)

Solution 1:

Okay okay wait I think I got this! It is all unallocated. I guess for whatever reason, unlike my Seagate HDD, I have to format my PNY SSD before using it. I took a leap of faith and just formatted it through Disc Management and suddenly it's got a blue bar, a new drive letter (E:), and it looks like I'm good to go!

Wow. I put this off so long because my tower is in a hard-to-access spot behind my desk and I never wanted to pull it out and check the plugs, plus I had no idea how else to do it-- now I know that's because I did it the right way, but it seemed like a challenging and frustrating task to find another way to hook it up when I thought it was done wrong.
