I don't think that will work, although you could fail/remove > an existing partition, then add the new one as a replacement. no, no...the existing arrays already have the "3rd" partition...I just want to add another complete drive, already partitioned exactly like the 2 that are already running.

I'm sure there is, you are doing the exact same thing I am trying to do! thx Les, John Rose
