Compatability for the NEW NAS RED 2TB Drives

Thank you for your help.  The real issue was not drive compatibility after all.  The Promise Technical Support teamviewered into my computer and resolved the problem.  It was just a configuration issue.  I have two other NAS - a Zyxel NSA221 and a Buffalo LinkStation which were automatically installed upon powering up.  For this Promise set, manual intervention was required.  I had erroneously assumed that the drives would automatically be recognised and installed upon powering up.  My Bad!!!  Case closed.
