Go back into the system page on the control panel and delete the drives again. Then rather than use reboot, go to the hardware installation gizmo and run it manually. See what it comes up with, just for clarity so that if it is still screwed up, you have something solid to tell a repair tech.
That is all I got left, except to open her up.
Okay, I tried that; delted them from Device Manager and went right to Add New Hardware.
It found both of them right off, then up comes the bubble next to the clock, saying "A problem occurred during installation; your device might not work properly."
It's got to be the drives or the cables.
