I don't have a Blade 1000, but have fitted a DDS4 tape drive in a Ultra
80, which from the outside at least looks similar to the Blade 1000. But
I've never looked inside a Blade 1000, and I am aware they are not too
similar.

Most DDS4 tape drives use 68-pin connectors. I'm told some HP ones will
work on a narrow bus, but I bought a Sony DDS-4. Someone then said that
whilst he got HP drives working on narrow, he was not able to on a Sony.
I gave up and added a wide SCSI card inside mine, since there is no easy
way of adding a wide device.

I really don't believe the SCSI ID is critical. My internal DDS-4 is on
SCSI ID=1, the DLT-8000 on SCSI ID=1 too (HVD, so different controller)
and I have an external DDS-4, (which I will remove soon) on SCSI ID=6.
So I have tapes on SCSI ID 1 and 6 with no hassle.

If the drive came from a 611 box, I'd try it back in that on the
external connector. I assume you did not buy it new, since DDS-3 is a
bit old now. So it could be faulty.

Also check termination carefully. I assume if it came from a 611 box it
is not terminated.
