x86_64 GNU/Linux

I have a two port eSATA SIL3132:

This gives me this two ports:

On ata6 I have a Lian Li box with JM393PM with 5 disks:

And ata7 is _unused_, nothing is connected to it.
However from time to time I see on the logs:

Questions:
- Is this a problem? Nothing looks wrong at the server, everything works
as expected, but I receive a page from time time because of this error.
- Is there a way to keep the ata7 port down? Kind of disable it.
- Is this the way to deal with this problem?
Are you sure ata7 is an unused port? I'm pretty sure there must be a
drive on that port and it's throwing errors on writes. Can you post the
full dmesg log?
