One of my hard drives (I have three) is vibrating in my Mac Pro. I constantly hear a low pitched hummmmmmmmm. I've reseated the drives several times, but I can't get it to go away. Do you think this is the drive itself, or the way it is mounted in the Mac Pro?

alligator, on mine it seems to be the front plastic fan compartment. If I squeeze the sides together, the sound goes away...I popped the case and when I push on that grey front plastic area, the noise stops.

Not sure how to fix it since there is such limited space between the case and the plastic..

I used a small piece of paper folded a couple times and placed between a HD mounting bracket and the computer case mounting point to help quite the buzz it was making. A little bit of paper works wonders.
