Does not check NTFS-formatted SD correctly Seems to be OK with FAT (and exFAT)? But when it tests my NTFS-formatted card, it starts writing at an unrealistic speed (40MB/s when successful writes using exFAT are more like 7MB/s) then it doesn't even read before saying my card is OK. Of course, when I opened it in File Manager, the card (or more liely the card reading driver on my Android tab) has crapped out again and it lists No Files.
