I have a Toshiba 64GB EXCERIA 1000x CF card and just bought the 128gb version of the same model. I've had the 64gb model for a while and has worked flawlessly but the newly acquired 128gb card is not recognized by my 7D every time I try install magiclantern with it. 128gb CF cards not doable with magic lantern with my 7D? What am I doing wrong? Please help. Thanks.
