'Check SMART Attributes' is grayed out.

I have an Intel 320 120GB, it has two partitions.  I also have my old Western Digital HDD as backup storage (also partitioned in two).  And for whatever reason I cannot check the SMART attributes for my Intel SSD, but weirdly enough I can check the SMART attributes for my Western Digital partitions using the SSD toolbox.

I have tried completely uninstalling and reinstalling the program but every time I click on one of my my SSD partitions in the SSD toolbox, the 'Check SMART Attributes' is grayed out and I cannot access it. I can access everything else, just can't click on that one feature.

What gives?  I wanted to check my SSD's media wear-out but cannot do that because I cannot check the SMART attributes.
