This error is not a media error, thus ECC correction is not being done.
It indicates that the drive is in a 'faulted' state.  If the error is
unrecoverable, you will see "try 2", "try 3", etc., in place of "try 1"
above.

It could be that the cables are a little loose (there are three between
the controller and the drive), or the drive could just be tired.
