    SE/30 internal HDD termination

    Hello everyone! I have a SE/30 that boots from the internal HDD only if a ZIP drive is connected. I initially thought it may have something to do with bad traces on the motherboard (and still haven't checked since it is not my area of expertise), but then I remembered: the HDD is a Seagate 8GB drive taken from an external Lacie enclosure. Is it possible that I have to terminate it with the switches present on the HDD? I found the manual for the drive but I am unsure on how to proceed. Maybe it has nothing to do with this, but the jumper plug on J2 is set to "term power from drive". Should I set it to "terminator enable", another setting or leave it as it is? Mine is the "N" model. Thanks.
  2. Dear forum members, According to SCSI requirements, the first and the last devices in a SCSI chain should be terminated. Since I have Iomega ZIP drive connected to the external SCSI port, there are 3 SCSI devices in a chain: 1. Macintosh SE FDHD itself - SCSI controller on the motherboard (SCSI ID 7) 2. Internal HDD (SCSI ID 0) 3. External Iomega ZIP drive (SCSI ID 5) The last device on the SCSI chain is the external ZIP drive, so it must be terminated. But what is the "first" device: SCSI controller on the motherboard, or internal HDD? In other words, do I have to disable termination on the internal HDD when also using an external SCSI device (assuming that SCSI controller is the first SCSI device, and HDD is the second device)?
