Possibly. It’s set for ID 0, which is fine. SCSI bus termination is a bit of a black art. You could try moving the jumper one place to the right (from TE to PK) to remove termination. PK (probably short for “park”) is a dummy position for storing a spare jumper. > 2. What would the jumpers be set to if this were put into an external > enclosure with scsi id 5? To select SCSI IDs, you just need to make sure every device on the same bus has a unique ID. The SCSI controller itself uses ID 7. Usually the primary internal drive is given ID 0, so that it is scanned first. CDs are usually set to 3 or 6, but check this or simply disconnect them for troubleshooting. So it doesn’t particularly matter what ID an enclosure is set to - the enclosure itself doesn’t occupy or enforce an ID. Usually the dial on the outside of an enclosure is connected to the ID pins so you don’t have to fiddle with jumpers yourself. If you really do want ID 5, you need to put jumpers on the rightmost and third-from-right pins (A0 and A2). It’s probably easier to select IDs 1, 2, or 4 by putting your single jumper on A0, A1, or A2 respectively. Or use your enclosure’s selector after connecting it properly. You could also try connecting the enclosure's activity LED (if there is one) to the pins just to the left of TE, where your jumper is now. > 3.

Giving a drive power usually helps with getting it recognised. You should be able to hear it spin up. - Jonathan Morton -- -- ----- You received this message because you are a member of the Vintage Macs group.
