SMART is only able to predict a relatively small percentage of disk
failures.  You have not ruled out a bad disk, but the more likely culprits
at this point are the controller/port and the driver.  Since the driver is
pretty well established even in 9.1 there isn't great cause to suspect
that.  You could try to upgrade the system to the newest release you are
comfortable with.  Otherwise plug that disk/cable into a different
controller.
