Fuze+ microsd card not recognized?

well, mea culpa, though it wasn’t easy to recover: I tried to reformat the card from inside the Fuze+ without success.  then I put it into a card reader and formatted it there, then put it back into the Fuze+ and it finally recognized it.  now I’m copying 28 GB of music onto it, if you don’t hear back from me it’s working fine…
