Forrest, Well, that seems to have done the trick. The array is currently "recovering" now. About 12 more minutes until the md0 partition is all done. I will let you know if anything goes wrong, but for now it looks like that was the solution. Thanks for taking the time to setup a box to test, etc. Really helped save the day! I owe ya a beer, which intel campus are you located at?
