That's the "termination power" jumper. If enabled, the drive
provides power for the terminator ... which doesn't exist on your drive.
I guess the jumper is there for external terminators that need power and
don't provide their own.

I think this is an IBM Ultrastar 18ES. See:
http://www.storage.ibm.com/hardsoft/diskdrdl/prod/us18es.htm
If so, this drive definitely doesn't have on-drive termination. See the
detailed installation manual at:

This means that this is an LVD-capable drive.
