hey recently i bought a sony nw-405 and i tried to delete all the music that i put on it. well i tried to delete the music like i usualy do in sonicstage but it just froze the application and didn't do anything. so i went into windows explorer and formated the disk using windows.. well that did remove all the music on it but now i can't upload music to it using sonicstage. i read some articles on this forum and it said not to format using windows explorer.. so i am a little worried i cannot fix this problem. is there a way to fix it without having to take it back to the store or paying $$ to get it fixed? thanks for your help
