Hello, The problem I am having is my 16 gig card freezes my fuze. I just bought the card and when I got it stuckt right in to see if it fit (without thinking to shut my fuze off first) and it froze. I held the switch to reboot and it did (without the card) and tried to start it up with the card but wit wont make it past the four color logo without freezing. So I tried my 4gig card from my cell phone and it worked fine. Not being one to give up easily I put the micro 16 in the sd adapter and my laptop saw it and I was able to put music on it. I then put the card in my fuze and it started up just fine. So I turned it off and went to work but it would not start up again. So I tried changing the files on it and now whenever I alter the card it starts up but wont start again if I have to shut it off. Sorry this is so wordy but I thought I’d try to get the whole story out of the way.
