- Insert card and perform a soft reset by holding the on/off button firmly in until a drum-roll is heard and then releasing it.
- When the device restarts, that is when it will recognize the card and ask if it can format it, to which you answer yes.
- If it fails to format the first time, introduce the card to your computer and perform a full FAT32 format on it and restart from 1.
After the card has been formatted by your device it will not be readable in your computer, as TT use their own proprietary file format.
