I built a PC yesterday with a 250gb ssd and a 2tb hdd. Everything went well with the build, and I turned on the pc and installed windows 8.1 onto the ssd while the hdd was not plugged in. After windows was up and running I installed a bunch of programs that were on my old computer, but stupidly didn't install any drivers for the motherboard or anything else. I then connected the hdd and found that it was not listed under "my pc". I asked my friend about this and he said the my hard drive is screwed, but he didn't elaborate. Do you know if I totally ruined it or is there any way to fix the drive/find it on my computer? If need be, I can always go buy a new one but I figure I'd ask here first just to be sure.
