According to my FastTrak Installation manual, there is a jumper that can be
set so that the controller draws power from either the drive (if it's housed
in a powered Xetec case), or from the host, which is what you want.  Look for
a jumper sitting on two pins labelled 'D Power', and move that jumper over to
the pins labelled 'H Power'.  The controller should then draw power from the
1000, and everything will be peachy (hopefully :).

Hope this helps.  BTW, have you thought about talking to Xetec about getting
some manuals from them for your FastTrak?  There is some useful information
in there, and I've got nothing but praise for Xetec's customer service (they've
always been very helpful with regards to my queries).
