I have a WD Elements SE 500GB USB 3.0 HDD. The problem is that when I try to use it with the following emulators: Visual Boy Advanced GX, FCE Ultra GX, Retroarch Wii, it shows some weirdly named directories that do not exist. I tried using a 16 gb flash drive and it works, but I really wanna use the HDD because I have tons of roms that don't fit on the flash drive. I formatted the HDD many times, and in different formats and the result is the same. Please help!
