To put my question more clearly, would a crashed internal hard disk disrupt the SCSI chain so that it is no longer terminated at the "internal" end? The upshot being that I would have to add a terminator to the SCSI connector on the logic board in order to use any external devices? As is suggested here http://support.apple.com/kb/TA27743?viewlocale=en_US.
Like this, I guess:
I will try to get hold of a replacement hard disk (or lift the external one from its enclosure), but before I perform surgery I would like to know if this (i.e. no internal termination) is a possible explanation for the fact that the computer does not recognize any external SCSI devices.
Why is it called a "daisy chain" anyway? It's not like all the other flowers in the garland will suddenly wither if you pluck one of them.
