My new Fujitsu 40 refuses to be a slave to the Travelstar 10. Or maybe it's that the Travelstar refuses to be a master for the Fujitsu.

have you tried to switch the disks around so the master is on the end of the cable, or vice versa? on pcs i've encountered cdroms coupled w/ ide hdds that refuse to be slave when its at the end of the cable. if i switch the orientation, its fine.
