Ok, I bought a WD SE 7200 80 gb hard drive, and it sounds really loud, I mean this thing makes the most noise from the case. Its a constant humming noise. Since my last computer was a 200 mhz compaq w/ 4 gb el cheapo hard drive (couldn't hear it), I don't know if my drive has a problem or not. What would you do? I'm seriously considering trying to trade it to someone (if it's not defective) for a Barracuda 60 gb.
