Here is how to check for the WD drive firmware from Apple System Profiler:
Click on the Apple icon on the top left hand corner
Click on About This Mac
Click on More info
Highlight Firewire (from the left pane)
then look to the right pane for WD My Passport Studio drive under Firewire Bus:
Under My Passport Unit:
Look for Product Revision Level: (it will say something like 1000)
That is the firmware revision for the WD drive.
Suggestion:
Try uninstall all of WD Smartware software.
Restart your computer.
Then re-install the WD smartware, then the update 1.2.1.25.
If after that, the Drive settings is still grayed out.
I guessed something is wrong with that drive.
You should exchange it.
FYI: We know that WD has not release any firmware updates for the Studio product line.
But I guess, we have to wait.
