The option ROM told me that I couldn't break up the array without losing data on the disk. If I don't break up the array, but instead just physically disconnect one drive, I'm not sure what will happen when I attempt to reconnect it.</P> Fri, 28 May 2010 23:33:44 GMT idata 2010-05-28T23:33:44Z https://community.intel.com/t5/Graphics/Breaking-RAID1/m-p/314140#M16654 <P>I plan to upgrade my OS and would like to break my RAID 1 setup first such that I make the changes to the OS on one drive while retaining the other drive as is so that I can revert to it if necessary.
