Ok, well my ad0 is a Western digital HD but I have notice that its spin =
down
some times. The strange thing is that I did not see this message when I =
used
5.1-Current so that is what spooked me.

Probably not.  Is ad0 by any chance an IBM DTTA or DTLA drive?  They =
have a
nasty habit of spinning down to recalibrate every 25 hours or so, and =
you'll
get timeouts while they're busy doing that.
