Hey everyone. Yesterday I brought home a brand new 2.66GHz Quad-Core Mac Pro. The Hitachi drive that it came with was unacceptably loud. It would crackle and pop endlessly at the slightest task, like opening Safari. I went and bought a 750GB Western Digital hard drive and installed that, and while it's certainly better, it still gives off an annoying amount of crackles and pops and "hard drive noise" at just about anything I do on the machine, let alone things that I DON'T do on the machine. Does anyone have any solutions or recommendation for extremely quiet drives? Maybe I just got a bad Western Digital drive, because I've heard that they're supposed to be very quiet. Thanks a lot in advance for any help/info that you can give.
