Won't let me enable write caching?

I’ve got two 750GB WD Blacks in RAID 0.

Then I go to enable write caching and it says “This device does not allow its write cache setting to be modified.”  Is there something wrong?  I know others that have write caching enabled with these.  What’s the problem?

You will need to contact your controller manufacturer as this is a controller/driver issue.
