You haven't answered this question :-) .

If the HD is "old" and accepts the 40-wire doesn't mean that the new DVD 
will accept and work OK with it.

No - switch these around. The HD should "control" the CD/DVD not the 
other way 'round. There is a reason for calling them Master and Slave 
:-) . (The DMA of the HD is a lot faster than the CD/DVD and you want 
the faster unit to be Master.)

But, hold on, you are now saying that they are Master and Slave whereas 
before you were saying that the DVD was configured for Cable Select.

If BOTH HD and DVD are configured as Cable Select, then the one which is 
connected at the END of the cable is the Master and the one connected to 
the middle of the cable is the Slave.
