So in my new rig my first hard drive seemed to be loud, so I went to replace it with the same brand just the 64mb chace version since it was the same price, but now it seems to be equal in volume, im not sure if this is te natural noise hard drives make or somethings wrong with my hard drive, please help. Thank you.
First try taking the drive out of the bay and setting it on a mouse pad or towel, something to absorb the sound (of course, with the power off). Start it up, does it still sound loud? If not your case mounts are amplifying the noise. See if you can use some o-rings or rubber washers between your drive and the bay.
