(In reply to Warner Losh from comment #44)
one of the power supplies is a 600 corsair (not going to take the other system
apart that also had this issue).  I will try a third one power supply when I
take this drive out of production service later this week and install it in a
test rig.

I have LONG since stopped buying inexpensive cheapo power supplies and have not
had a problem since with the power supply failing or dropping power. It could
be these 2  systems both have their power supply failing in the same way but
that seems to be a bit of a stretch.

When I get the 3tb WD red on Thursday I will copy the Blue drive to the Red and
install it.. if the system stops failing it is pretty reasonable to assume it
isn't the power supply.  Then I will test the Blue with the original install in
a test rig and (completely different power supply, motherboard and cpu) See if
it continues to fail.
