Good to hear.  Boot the server to the controller BIOS (CTRL-R), once there then scroll to the VD containing the foriegn drives and highlight it. Then hit F2 and go to Foreign Config, select to CLEAR FOREIGN CONFIGURATION. Once that is done then you can go back and highlight the VD again and hit F2 and select to DELETE the array.  That will free all 4 drives to be configured in whichever way you prefer. Let me know
