Hey guys, For people who have experience with WD Scorpio Black 320GB harddrive, i was wondering if you can hear a humming sound when its in your macbook. To better describe it: The humming sound (very low, if your fan turns on, it will over power the humming sound). It seems to truly exist on specific desk woods. When I put it on my lap, I don't hear the sound. I have to put my ear next to it to hear it. But when i put it on a Ikea desk, the humming resonances to a high sound. I can block it out but wish it didn't exist. On glass, I don't hear it and other woods, i don't hear it. Do you experience the same thing? Also, i think my macbook is 1.5GB/S Sata motherboard so I don't think its possible for me to unleash the 3.0GB/S furry!@!!~! ???? How are your benchmark numbers. I'm trying to see if the performance is worth it compared to just going to 5400 rpm. Any input would be great. i have 30 days to return this drive. I don't feel alot of vibration. It seems like the vibration can be felt on that Ikea desk wood, because the resonance causes a feedback loop causing the laptop to vibrate.
