A lot of discussions instead of plain testing... what's a 16 or 32GB card today, some 10€. Big loss, if any, for it may be used in other projects
If people having troubles using SD cards would format them with care, this won't happen. In this context 'care' means that one has to pick up the type, namely FAT32, and not what wmodern windowses recommend, namely exFAT, which won't work.
