What I have: Inside Tower: Adaptec 2940 Card | | | V Sony CDU-76S CD-ROM (4x) | | | V Seagate ST32171N (2 gig) The back of the tower is a SCSI-1 connector and a SCSI-1--to--SCSI-2 cable to a SyQuest EZ135 drive which then connects to a MicroPolis 1598-15MD1066702. The MicroPolis is a full-height drive. It is in a case with space for 2 such drives. The case DOES NOT need to be terminated. The above setup has worked for months and months and months (April). I now have a new-to-me Seagate ST-31230N. I ran 'verify media' on it, and it came up just fine. I installed a DOS partition on it (10 megs) and FBSD 2.2.5 off the CDs. It works FINE but only if I remove the other Seagate drive and disconnect the external devices I cannot seem to put the new Seagate in the chain anywhere without causing system panics and SCSI timeouts. I have tried to put it between the Adaptec card and the CD-ROM (inside the tower) and in the external case with the MicroPolis. The Adaptec is set to DISable Termination. I am guessing that this is a termination problem somewhere, but WHERE? How do I fix it? I've got the spec sheets for all 3 drives but don't really know how to read them.... TjL
