what's going on?! I just got my HDD replaced, because I got a crappy loud Seagate before, and now it sounds like a freaking airplane! What's going on?! And is there a fix for this? EDIT: I shut down the computer for a few minutes and started it up again. Not as loud, but the fan is now spinning at 2800rpm. This can't be normal.. and it definitely wasn't like this before.
