That is already done.  They are never connected when I boot up anyway. 
I did the same on the NAS box as well.

I meant the info in the messages file when powering up the drives were
the same.  The enclosures are a bit different but they are all eSATA.  I
did swap out the enclosure and the other did the same. I may put that
drive in a Rosewill and see if it works as it should then, eliminate the
drive as a problem.  I have three Rosewill and two Startech. 

I've seen those limited to smaller sizes in the past.  Generally tho,
they always work regardless of size unless they really small like older
IDE drives or something.  I read once what causes that and don't buy
those.  Usually if I read it in the description, my bell goes off.  I
haven't seen one that is actually limited in ages. 

Good idea tho.
