LTO6 and T440

I was told in an earlier discussion that an LTO6 using an Ultrium 4 tape can connect to a T440 via a 12Gb SAS HBA controller. I have installed the controller and connected the LTO6 with the tape in it. It appears in my drivers and device manager. I have asked it to update with it telling me it is the most up to date and I have downloaded the drivers from your website related to this device. 

I still cannot see the device in "This PC" or anywhere. Any idea what I could be missing?
