- YES. According to specs of SCSI drives, you should only terminate
- both sides of the bus. So in your case that would be the interface
- and the last physical drive. The logical drive does not matter. On the
- other hand. When connecting a second ST157N to my TT there is a all
- different story. Ask me if anyone wants more details.
