I have purchased about 2months ago a sandisk ultra microsd hdhc for my samsung galaxy tab2 7.0 from bestbuy, but everytime I try to write something to the card on my computer, it detects it being inserted, but gives me an error saying that the card can not be written to. My tablet reads it fine, but my computer cant, and I did install the windows 7 update for 32gb or larger cards. If someone could help me with this, that would be great.
