With regard to the formatting of cards it seems that the best option is FAT32 (even better to format with the X5). There are a lot of variables in file systems and how they manage data, and it's very difficult to manage an interface with so many options for the end user. One reason Apple products run smoothly is they offer only a few music formats with a specific OS/file system/disk format. With far fewer user variables the experience is much smoother. Fiio is trying to offer us a wide range of options for playing our music but I would recommend using only FAT32 formatted with the X5 for the cards. On second thought Fiio should state that this must be done using the X5 hardware, similar to what every digital camera does, that way they can focus on UI, music formats and sound quality and not chase disk formatting variables that can't be predicted but take a large amount of time and effort to troubleshoot.
