HDD Broken?

[GymothyCharles]

Hey all.
Today, i went to the store and bought a gtx 970 twin frozr v edition.
When i got home, I went straight to installing it. I took out my old 9600gt without uninstalling the drivers, because i was in such a hurry to try my 970. I installed the 970, and started her up, and i got a screen saying error, there has been a hatdware/software change, please put in your win8.1 disk and go to fix my pc. I did this and selected advanced options, then hit automatically fix errors. I restarted the pc, and it worked, aside from the resolution being off a bit, which i fixed immediately. But all of the programs were either missing icons or not on my desktop. I went to "this pc" and checked, and sure enough, there was no 2tb hdd showing. My ssd worked fine, but the hdd, not so much. I went and undid the back panel, and found the sata power came out on the hdd, so i plugged it in, started my pc, and i still have the problem. I tried to partition it, put windows couldnt find the directory for the partition editor. I need help.

Well check the power cable connection on the PSU side and then check the SATA data cable both on the HDD and mobo side. See if the cables are connected properly. See if that does something.

maybe im an idiot... what i can hear is the fan right next to my hdd...

The sata power and data are both in, i might try replacing the sata power though, see if that helps.
