    I'm trying to format a Toshiba 32GB UHS Speed Class 3, Class 10 mirco SD as internal memory on my HTC desire 530 (Android Ver 6.0.1).

    However I get the error: SD Card Too Slow
    "This SD card is too slow to use as internal storage.
    To format an SD card as internal storage, try using a Speed Class 3 SD card."

    The card formats as internal on my friends HTC M81 (Android ver 6).
    Is there a work around or fix for this? I have tried restarting the phone, formatting the SD card, removing the SD card.

    Welcome to Android Central! The card might be counterfeit. Try running SD Insight.

    SD insight says its a Toshiba model SA32G, plus it was purchased from officeworks which you would hope aren't getting counterfeits in.

    Hmm, I'm not sure why that's happening. Are you able to try a different class 3 card?

    It may be worth bringing the card back to Officeworks and asking for an exchange or refund.
