I have an SE/30 with a standard Apple 40MB Sony Internal.
I have just bought a Quantum 210 external .It came in an external
box, with a cable, but no terminator.  It works fine, though.
Now, I want to put the 210 inside, and keep the 40 external, so I had a go,
but it went nuts - sometimes it crashed, sometimes it appeared to work, but
actually was stuffing up files behind my back, and generally caused problems.

In switching the drives around, the only cables that needed to be played with
were power (easy), data (easy) and scsi ID.  On the sony internal, the six-pin
connector for the ID was not connected to anything, but on the external, it
was linked to a clicky-id thing.  Once I had switched them around, the ID
selector worked OK on the sony, and I left the ID pins on the Quantum free (as
the Sony was previously).

What's the problem ?  Is it internal termination ?  If so, why does it work one
way, but not the other ?  Is it the ID pins on the Quantum ?

Any help would be appreciated !

BTW, the drive uses it's own driver - apple's HD Setup refuses to acknowledge
it's presence.
