So I have been studying this problem for a while now nonstop ever since i got my new 2TB usb drive. It uses a 4b allocation unit size. Which is already known to not support the Wii since the libs are hard codes to only support 512b. I tried formatting the drive to 512b using Fat32 and NTFS in multiple sizes below 1TB or above 1TB all resulted in: "The selected allocation unit size is too small for the selected file system" I did notice however applying 512b to exFAT (Fat64) will work but the Wii doesn't support exFat. So as of now there is no solution, but is it possible that there will be one? Either making Wii libs support 4kb clusters or making support for a new file system eXFAT. Devs please help out here. Also to note I bought this drive for media (Movies, music, pictures, tv shows) Not for a shitload of pointless games. So please help.
