Yes indeed, the only solution for some SD cards that worked well on my ak120/windows/imac but not read on X5, is to format them using the X5 itself. I did this the day before yesterday and well the X5 formats very fast, which is great, it names tbe SD cards as X5 card 1 and so on, and from then forward they play and read very well on X5, AK120, windows and macs. But i urge Fiio to address this issue on the next firmware update, cause it is not convenient for many people to format their SDs and load them again. Not to mention that SD swapping between friends will become a trend. So me and my friend on a road trip or so, i got bored from the music on my SD, i wanna use his SD, this should be easy.
Another issue i wanna raise is: i have clearly noticed how slow loading music from computers to the SDs when they are inserted into the X5, its much faster to take them out and plug them directly into the computer using the USB adapter supplied by fiio. Thats also a little inconvenient. The SDs i have inserted into my AK120 became part if the machine, i easily plug the AK120 into my imac and delete and add files as fast as a usb harddisk. I dont want to take off the X5 cover, struggle with the rubber SD lids and tke out the SD, look for my usb adaptor plug it in change an album then do the whole process to put it back into my X5. all can be avoided with a better file transfer firmware
