Hi all Quick question - just collected my 128GB S9+ today from the store, and it came with an additional 128GB micro SD too, which the guy installed for me. On hooking up to PC to transfer some stuff, I notice this card seems to be pre-formatted to "generic hierarchical" format, the same format used for the internal memory in fact. So should I leave it on that? Or reformat it to exFAT or something? Not sure as biggest card I've had up to now is a 64GB SDXC. EDIT: I've done a bit more digging and I did find a hint from somewhere that this "generic hierarchical" just shows up in Windows when the media is being accessed through the MTP or similar protocol, ie connected via the phone USB. If that sounds correct?
