Well, oddly enough, even though it came from the factory formatted, and it was working perfectly moving files and playing songs when plugged into the pc, re-formatting it under xp seems to have solved my problem. Now the player see it and plays the songs I put on it. Evidently there is something about the fat32 file system put on the card at the factory that the player – but not the pc – didn’t like. At any rate, it seems that I have solved my problem. Thank you everyone for your comments.
