Which disk is it booting off? Assuming it is the one that it *is*
seeing then unplug the other one and see if it is then ok.

I agree it seems like a hardware issue. You could try swapping round
the connections to the discs to rule out the cable.

You have not said whether all was working ok and then it stopped, or
whether the problem started when you connected the second disc.
