How can I find out what is hammering my harddrive? I checked "ps aux" and all seems normal. I can "df" a few times in a minute and see my free space go down. I have installed 10.7.4 twice but had to restore to 10.7.3.. I did CCC'd it onto a 2.5" sata drive, which I will be using for testing. I don't want to mess up my SSD.

EDIT: I installed SONAR FILE MONITOR and there is NOTHING showing up while the HD light blinks non-stop. I disabled Spotlight completely. I even emptied the /var/log and /Library/Log folders and I chflags uchg them and the blinking doesn't stop! UGH!

EDIT 2: Well I just found out my 10.7.3 install started doing it also. And when I booted 10.7.4 it wasn't doing it. I will capture everything I can (ps, top, etc etc) in both scenarios and compare it to see what could be causing this...
