You need to format your external sdcard using FAT32 and you will no longer have this issue regardless
of which rom you might be flashing in the future.
Here is the direct download link for the fat32 formatter for windows.
You will need to remove your external sdcard from the phone and plug it into it's adaptor or card reader
then copy all files/folders in it to an empty folder on your windows computer so you can have a backup
of all your files and folders.
Then format with fat32 and afterwards copy all files/folders you have backed up back onto the external
sdcard and put the microsd back into your phone.
