SCSI HDD troubleshooting

Hi,

I added 2 SCSI drives through the A500-HD+ . I see the termination drive #5 just fine, but #4 which it passes through doesn't show up on the desktop. Faulty drive? Would it pass through signal even if I turned it off? Does it matter which SCSI-port is in and which is out?

I have a CD-drive on the parallel port but I guess that doesn't matter. Just in case, checked assignment  #2.

So what IDs are you using on each drive? Could be both set to ID 0. You can’t use the same ID number.

I can select numbers on the back of the devices, they are 5 and 4 on SCSI for the HDDs, non-5,4 for the A500-HD+, and 2 for the CD-drive.

So. Can you not change the HDD’s to 0 and 1? I take it the host controller is ID 7?
Or in some cases, some SCSI controllers don’t support higher ID’s for HDDs.
