I just purchased a CDM8940 and i also purchased a SanDisk 256mb miniSD card and when i tried to format the card from my phone it says format failed. I've read in other forums that you need an mp3 folder formatted onto the card to put the songs into that folder becuase it's the only way the phone could find the songs. If theres another way you can put an mp3 folder on it could somebody help me out and tell me.

Thanks
