I found out the hard way that WBFS has a file system limitation of 500 games. Yep… no matter how large your drive it will hold 500 games. The average Wii game size on the WBFS drive is about 1.71g so on a 1TB drive you’ll have almost 80g left over you can’t use. WBFS Manager 2.5 and 3.0 have bugs and will tell you the games were added to the WBFS drive but they actually aren’t. If you try to add games from the DOS version of WBFS you receive the following: no space left on device (table full): No error So… There doesn’t seem to be any practical reason to go any larger than 1TB for your WBFS drive.
