Why can't my fuze read my 32gb sandisk microsd?!

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.
