Hey all. I'm defraggling today. I've recently had some doubts about the health of one of my drives, so when I began defraggling, I had a look at the Health tab in Defraggler. It reports everything as being fine, and this isn't what I'm calling about anyway. What I do want to know is, where does Defraggler get its drive temperatures from? It reports three temps - the bold green temp at the top of the tab, with the overall health stauts, and then in the breakdown list on the right it lists airflow temp and overall temp again.
So, do standard HDDs (which these are - regular old Saiteks and WDs) come with some tiny heat sensors or something? Or, are these just default values that display when there are no sensors rigged up?
