Comment 584 for bug 59695

erythrocyte, I guess it still doesn't work in Intrepid, at least on my Dell Inspiron 1520 with a <a href="http://www.seagate.com/ww/v/index.jsp?vgnextoid=c7de03cf785c6110VgnVCM100000f5ee0a0aRCRD&locale=en-US">Seagate Momentus 5400.4</a> it didn't.

I did some testing, maybe this helps for debugging. I tried changing the bios settings for HDD Acoustic Mode to all three options ("bypass", "quiet", "performance"), but it didn't seem to make any difference, the cycle count kept increasing. I've tried to suspend my session, but after resuming the clicking was still present. After hdparm -B 254, the clicking stopped for good :)
