Seagate ST32xxxN defective?

It is possible that it had a built in terminator on the drive.  Some SCSI drives have a jumper to activate it or bypass it.

At least my 4 GB UWSCSI SG has one.

@leofoe,

Yes, I have two ST32155N's working: one in a 3000 and one in an external SCSI enclosure connected to a 4000 thru a Fastlane. For a little while, I had both of them connected to the 3000 and they both worked fine together.

I tried one of the disks in a PC. After a lowlevel format in the Adaptec SCSI controller utility it was recognized in WinXP. I formatted it there with NTFS.

Then I connected the disk to my Amiga but, unfortuantely, was not recognized by HDToolbox.

@leofoe,

So at the moment we know the drives are definitely good. That is a good start. Now it's just a matter of convincing them to play nice with your Amiga...

The jumpers for your drives are all the same as the ones for my Hawk ST32 drive. Can you try just one of those drives in your Amiga to see if we can get it working? And if so then move on to the others? Set the SCSI ID jumpers so it's unique. Now on my drive, I have a jumper on "TE" (enable termination). I also have a jumper only on the "TP" next to "RES". The other "TP" is open. This sets it to Term power from drive.

There are many more options. I do not have jumpers on these: "DS", "WP", "PE". I have a jumper on "ME".

That is how the drive is working in the 3000 with termination.

Now if that works, and you want to add the second, all I did was remove the jumper on "TP" and "TE". Everything else stayed the same.

Hopefully this will get it going for you!

If you think you might have troubles/conflicts with external drives, try disconnecting them and properly terminating the external side so the HD in question is the only SCSI device.

I got one ST32171N working! It turned out to be a termination problem after all. Every time I had the TE jumpered and thought that was sufficient as termination. Then I tried a cable with a terminator at the end. That did the trick. This cable was not necessary on the PC.

I will now try the other drives and a CD-ROM player as a second device.
