Hiya!
Just want to say a huge THANK YOU! to you! I was aiming to get the MH Poka Poka Airu mura whilst it’s on sale (ends on monday!) and bought a 32gb Sandisk extreme off ebay to expand my currently 16gb sd card, tried and tried to follow your guide and all was in vain.
Turns out that the sd card from ebay is a duff one. Bought a PNY one from my nearest computer shop and voila! Everything moved to the new card w/o a problem.
Thank you again!! Great stuff!!
