one option might be that the cards are actually incompatible, but i doubt that.
it is all in the formatting. back up all your current files, then use either hp formatting tool or a partition manager like easeus partition master to format the card in the exact way, described. SLOW format is required. if you checked quick format, it cannot work. make sure to use the exact allocation size, given in the tutorial, then, in case you use a partition manager, wipe the partition again, just to make sure.
then copy your android files on it and make sure to unmount the card reader in windows, before removing the card and then it should work.
