That is how we learn Andy  Any data I put on this stuff while testing 
as normal files will be expected to be lost.  So that possibility is 
expected. Experience is how I got where I am on an 8th grade education.

Expected.

I'll try.

When I get it assembled. Last 2 drives s/b here tom. Then I need to shut 
down and extract 4 of the gisastones which are plugged in atm but 
unmounted, the 5th one is now my /home partition. And I am rsync'ing 
/home back to that now idle raid10 about every other day.
