    Wasn't this mentioned before? ;-)

    Some devices will choke on a wide negotiation message. The driver
    will accept a rejection message from the device and disable wide
    negotiation causing no ill-effect. But if the drive doesn't respond
    with a message reject, the command probably timesout which is more
    difficult to deal with.

    Probably.

    Check out http://www.scsi-cables.com/line/scsiterm.htm

    I use an active terminator on my external (wide) box. I also
    use an internal in-line 50-pin active terminator at the end
    of my internal (narrow) SCSI cable.
