c200 AND WINDOWS MEDIA PLAYER

MY c200 WAS WORKING, BUT NOW WHEN I PLUG  IT IN I CAN’T DELETE SONGS. WHEN I GO INTO SONG FILE IT SAYS NO FILES FOUND ON THIS DEVICE.I CAN SYNC. SONGS. I’VE TRYED TO REFORMAT AND THAT DIDN’T WORK.

Please dont type in all caps =(, its  an eye-sore.

What does it say when you try to format the player? “windows unable to format” ? Does it do the same thing if you try to format the player through disk management?
