I'm not sure how far you are down this path already with the new drive, but I have a 2TB Hitachi as well in my MythTV box and found it to be quite noisy. I found that setting acoustic management via hdparm helped greatly for me. If you're running Ubuntu/Mythbuntu, you could try adding the following to /etc/hdparm.conf (replace <X> with the appropriate drive letter) and then reboot:<div>
<br></div><div><div>/dev/sd<X> {</div><div> acoustic_management = 128</div><div>}</div><div><br></div><div>This can also be accomplished using 'hdparm -M 128 /dev/sd<X>' (and possibly set in /etc/init.d/rc.local for other distributions).</div>

I'm about to replace a noisy Hitachi 2TB drive with a hopefully quieter<br>
WD20EARS. Usually I just use dd drive to drive, but if its worth<br>
changing some defaults and do file copies I might do that. The<br>
filesystem is pretty full, so doing file copies will be slower than the dd.<br>
