I have this MP3 player also only been a very short time, namely since Christmas 2005. And every 3 days also I get the message: "Incorrect format - reformat the player" You have to run the software on the CD-Rom and format the entire data area of the player really every time !! That's just annoying, inconvenient and unacceptable !!! The player would be a great device because I unto this (units?) / (Software?) - Error'm very happy with him ... If anyone has tips I would be very grateful in this respect and I think other customers who have the same problem! MFG Summa
