Brenda, After poking around and Googling, I *think* the problem is due to the way the Ubuntu shuts down the RAID array ( http://www.linuxquestions.org/questions/debian-26/disk-might-not-be-spun-down-properly-update-shutdown-utility-583307/#post2926448). I am trying various ideas and will report to the list latter this week. Thanks! Charles On Tue, Jan 18, 2011 at 10:00 PM, Brenda J.
