Pearl rio carbon mp3 player 5gig

The microdrive is probably broken. Some people have claimed that if you give the sides a sharp tap then it has worked again but if this doesn't work then you probably require a new player. I have managed to replace the microdrive with a CF card in my Rio carbon, this has worked for many people may not work for you (you can read this: Replace broken hard drive with CF card if you want to try)

Hope this helps,
