Not a good typer or speller :) here is what I didSince I could not format it on my Pc Running WIndows 8 Pro or any of my cellphones running Android versions of 2.3.1 from Republic Wireless :).On my Canon Vixia HF M41 dual card Camrcorder I formated the card but the thing is, it still read as exFATso I mounted it onto my Samsung Galaxy 10.1 anyway and it said something about corrupt files or what ever and it asked If I wanted to format and I press ok and yeap it works now It reads about  54 gigs and some. Got this 64 gig  baby for $19.89 from Amazon Warehouse deals. I bought two but they cancelled one for no stock but it was still showing stock, oh well all I really needed was one I just got greedy.
