I would like to get a clarification on this. Does either drive work
fine in the PD0 position or does the drive that was not working in the
PD1 position not work in the PD0 position? You said that the spare drive
that you put in the PD1 position also does not work. I would try it in
the PD0 position and see if it works or not. Would you please let me
know on these items?
GOD Bless and Thanks,
