Somewhere on the Mountain drive there is a jumper that is used as a drive
select.  Most drives are set as drive 0 (0 - 3) or drive 1 (1 - 4), depending
on how they label it.  You need to set the Mountain drive to the next drive
number.

Because they are both at 0 (or 1), they are both trying to answer the call
and they both end up getting ignored.

Look near the connectors.  The jumper may be hidden and require a tweezer to
grab the jumper to pull it off and move it over one position.
