I have taken the 100 gb disk back to the store and I now have a Seagate 40 gb running. I was able to load songs on the initial synch and everything was fine. At the moment I am trying to put some more songs on the player and have noticed that the synchronising icon is frozen on the player. Emplode is in the "uploading tunes" mode and the is a warning that one song(so far) couldn't be synchronised. Emplode shows that it is writing a song but the blue bar doesn't appear to be moving and I would estimate that it's be like this for 20minutes and I'm not touching it until someone points me in the right direction!
