I realize that it's not supported and only 1tb drive per tray is supported. So, if I just replaced the 250gb drives with 1tb drives and then rebuilt the array, how do I get the extra disk spack to show up? I replace one drive at a time, then click on rebuild array until I do this for all 4 drives. Once they are done, it still shows the total disc space at 750gb instead of 3tb.
