Lyle (& Rodolfo),Thanks for your help on this one - I'll just ignore it from now on given the details below (even though we recently hit the 48% collisions during a particularly large copy).

Wow, an original! The collision detection and warning for the Qube 2700 never really worked well. It tended to go off when doing large file copies. For this reason, we took collision detection out of subsequent products. You can safely ignore this "error" state. - Lyle
