Memory issues on external memory card in my MP3 player?

Question

I have a 1 GB MP3 player with a 1GB external card in also. For some reason my external memory shows that there is almost 50MB of unused memory,but I can not utilize it. It will not allow me to put any more songs on it. How can this be?

Answer 1

sometimes that space could have been put on reserve that space would not be available for user memory
in that case u wouldn't be able to add on memory
