I'm trying to get a 68pin seagate st32430W scsi drive to work in my

may be what's wrong but I have a feeling that it has something to do
with the jumpers.  I've tried a few combinations for the jumpers but
none seem to work.  Could someone please look up the drive and explain
where I should and shouldn't have jumpers in order to have the drive
as a storage drive (not the primary boot drive nor the last
drive/device on my scsi chain) in ID #1 or #6.  Any help would be
greatly appreciated.  Thanks.

Unless hte adapter that you are using terminates just the upper 18 pins of the SCSI cable, then you *MUST* put the adapted drive at the end of your SCSI cable. The reason is that a 50 wire/pin SCSI bus only has termination on 50 pins. A 68 pin drive on a 50 pin bus still needs termination on the remaining 18 pins.


There are two ways to supply this. Either use an adapter which only terminates the upper 18 pins (yes, they exist). Or put the 68 pin drive at the end of the 50 pin cable and terminate all 68 pins of the drive.
