32, 64, 128gb doesn't matter. They all update fine with or without music on the the card.
The 32gb blank card recommendation came about before Fiio included the format tool in the device (X3 and then X5) and people were all over the map with formatting software and options which caused Fiio a lot of headache. They spent so much time troubleshooting problems that had more to do with the formatting than the DAP.
Recommended to format cards in the X5 before loading music and you can be sure it'll work every time (unless something is seriously wrong with the unit or card or files).
