It now operates as normal but flashes this message on start-up. I believe the player is not at fault now, it’s not 100% since I left it in a friend’s car for 2 months but sorting itself out as it gets used to being used again, or perhaps it’s just me forgetting a few “eccentricities”! It detects the card, seeing the correct amount of free space and it is a Sandisk 4gb Micro SDHC.
I’m using the sync function on Windows Media Player 11 which sees the card (separate to the MP3 player but as an expansion card as does Windows explorer, claims to be writing to it but only gives it the name of the albums I try to put on it but not the song. Does this give you any clues? Thanks for the reply.
