It sounds like either the Seagate has gone bad, or termination isn't 
correct. I'm not familiar with the rules of wide drives on narrow 
buses, but only one device should be providing term power to the bus, 
and only the last device/end of the cable should be terminated.

It's also possible that the drive is attempting to negotiate sync 
transfers or inform you of a drive error, or its a bug in the driver. 
Does the same thing happen if you remove the delay motor start enable 
jumper? The rejecting extended message part isn't necessarily bad, but 
the disconnect definitely is.

It's weird that it reports sd0 as offline when it quite obviously is 
not.
