Yes the sd card works perfectly on the phone view pics backup with astro and titanium. Play music store stuff etc. Nothing wrong with it but it says its busy/not mounted in recovery. Also the recovery reads it for like 1 or two steps during installation it will say sd card busy. Or it will say that right from the beginning without any attempt to installdid you try to restart your phone? does it see your sd card when using astro or something familiar?
