Good news there, I will be gettin my owc 120 very soon

Did you do
fresh install Osx and all aps?
fresh install Osx + data migration?
CCC old hdd image to new?
Have you disabled hibernation and stopped sleep- or does it all simply work ok?
with osx and all apps
I did a fresh install and used time capsule backup (migrate user). First I did not change anything and it worked.
Now I am using SmartSleep http://www.jinx.de/SmartSleep.html
