Problem setting up Stripped Array with EVGA 680i MB

I used the BIOS to create a striped raid with 2 300GB WD Raptor drives and it reports I now have a healthy stripped array.  However when I boot into windows 7 -64 bit the drives no longer appear in the storage manager and device manager.  I have another stripped array with 2 1-GB drives and it is fine.  What is causing this array and the drives to vanish?

I have noticed one other behavior that I don’t understand.  When I enable raid on the two new drives they disappear from the storage manager and device manager regardless whether I create the array.  The drives work fine if I don’t Raid enable them.

Any ideas?  

Maybe you should try contacting WD’s Technical Support about this. You can do so either by phone or email.
