I know many people here consider the web based Sonar forum to be evil, but I found this very useful thread on PCI latency timers : http://www.cakewalk.com/forum/tm.asp?m=45491&mpage=1&key=reclaim,sata The original poster was attempting to remove pops and clicks caused by his SATA controller, but it seems to clear up a number of latency and "pop and click" issues. Definitely worth a read.
