Does anyone know how to set jumpers on a SCSI drive to use 2 HDs?
I have the address jumpers down, but what is "drive motor enable" and "parity/no parity" mean?

The different scsi units must each have a unique address on the scsi bus. The controller is always address 7, and your two harddrives could be 0 and 1. Drive motor enable should be set to 1. It is most likely used to control wether or not the drive waits for a Start Unit command before it spins up. Parity is used for error correction and should always be enabled. Have you remembered to terminate the scsi bus correctly and enabled the supply termination power jumper on your scsi units, if they have one that is?

Also, OS 3.1 will not read or save to my
Seagate Barracuda 15150n drive. I have tried every jumper combination that I can think of and nothing works. Maybe the drive is bad?

Could be. If you have access to a pc with scsi you can test the drive there.

HD tool box will not read the drive info either.
Help meeeeeee. :-x  :-x


That most likely though is because HDToolbox isn't configured to talk to the driver for your scsicontroller and instead just uses scsi.device.
