I have a fuze mp3 player and I bought a 32gb sandisk class 4 micro sd card for it – but it won’t read it! (The player knows there’s a card in there, but it says it’s “empty,” when it isn’t.) The card works fine on my computer and passes tests with chkdsk and htwtest2. Anybody have any ideas what I need to do to get my sandisk player to read my sandisk memory card? Thanks.
