can somebody explain why after a reset of the phone to factory default (using *#7370#) I always get the message "Preparing memory card" (on N6220c)? I removed directories on the memory card for automatic installation of SISX. Still this message appears ... what is the phone doing to prepare the memory card ... why is this step required?

(basically - can the phone not prepare the memory in its own time instead of keep me waiting ... on a PC memory card seems not really need any preparation ...)
