Well I hope I have not damaged the drive

Yes I substituted another cable (It did not come with any cables, they were
removed with the drive)
It was properly terminated by an external terminator. As I said after boot
from the CD a drive on the
single ended bus was detected ( and the CD and Tape) by the kernel but was
not detected by boot.

It has been suggested by someone else (they did not reply to list) that I
boot from CD which seems to me
the easiest work-around.

Thank for the assistance,
