Speedfan smart values should look like this (you may have to click on the smart tab to view the pic):http://www.almico.com/sfscreenshots.php
For hdtune, see this page. Scroll down a ways for the screen shots. It's the picture on the right - click it to view.
If smart is disabled in the bios, then windows is reading values directly from the drive, bypassing the bios.
HDTune will just show OK in the status column. Speedfan put an OK icon next to it's categories. If there is no status, then the value is irrelevent or not used.
