That has been one of my ideas too and I have already checked and swapped
cables - but no success. I couldn't change the backplane as I don't have
a spare one.

But there is one thing though that crossed my mind just seconds after
I've hit the 'send' button!

I periodically check (every minute)  the drive temperature using
'smartctl -a' and I only query one drive - '/dev/sda'! So I re-checked
my log files and indeed - the SATA error ALWAYS happens within one
second of the 'smartctl' command (but not every time).

So now I changed the scripts to query a different drive ('/dev/sdb'). In
a couple of hours I should know if that was it...

  Thanks for the help, Danilo

PS: Oh, one more thing - the 'sda' drive is a WDC, while all the others
are Seagate.
