Okay so I have a WD Caviar Black 1TB. I've had it and the rest of my parts since august. Just today, it started making this really odd whining noise (or I could have just noticed it). It was somewhat quiet so I did a few things - turned of the computer, opened her up, tried to see if it was the fan by unplugging it, googled YouTube videos to see if the noise was normal, etc. About an hour later, I deem it normal and got it running again, starting up my Sims 3 game. While loading the game, the whine came back with a vengeance (I was playing the Sims 3 when I noticed it first too.) I paused and thought, maybe it's from loading the game? Well, then the noise kicked up a pitch, my heart sank, and I turned the PC off (Typing this from my macbook). I don't know what's wrong! It's not making those usual noises of a failing HDD - clicking, thumping, the works. So what is it? It sounded somewhat like a bad speaker whine, you know? Please answer soon. I'm afraid to turn the PC on.
