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. > Flipping the drive over, we have model: > > DNES-309170 E182115HG 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: http://www.storage.ibm.com/techsup/hddtech/dnes/dnes_di.pdf > SCSI LVD/SE This means that this is an LVD-capable drive. -- Darryl Okahata darrylo@sr.hp.com DISCLAIMER: this message is the author's personal opinion and does not constitute the support, opinion, or policy of Hewlett-Packard, or of the little green men that have been following him all day.
