Hi, so first of all I want to aplogize for sucking at this cause this is my first time ever doing this.

So, I bought a WD red 2TB hard drive and I inserted it into this hot swap compartment thingy in this computer I bought last summer.

The problem is, it isn't detecting my hard drive in disk management. I know for sure that I've inserted it the right way and it still isn't detecting it at all. Did I forget to do something, or is it just supposed to work once inserted like I thought?
