Perhaps you can connect the device to your computer and format all the memory? (you should make sure this is a safe option).
the MP3 screen is lit up and when i turn it on it says "invalid id memory can't find mbr" and it won't move from that group of words. i can't change to the radio station and i can't get to my music files. i can't even turn it off without taking out the battery can smeone help me pleez?
