Jules, 

have a look at the biggest database for harddisk drives: www.pc-disk.de
All you have to do is to click on "producer", then on the left, you can navigate down to the Seagate drives.
For the ST1480N, there is the layout of the PCB and the jumper definitions where the termination power is 
pointed out as well.

Regards,
Pierre
