    If, when it unmounts, everything is gone from it, I'd say that he card is going bad.

    Unmounting should only keep from corrupting when removed. Formatting will delete its content.
    Try another card to see if the problem is with the phone or the card.

    Pull it out and gently clean the gold contacts.
    Isopropyl alcohol is good, methylated spirits... NOT detergent based cleaner, the water will short out and kill the card.
