Hey Guys, So I have 4 Wii's I got from eBay at a really decent price and I'm setting some of them up for friends. I have a slight issue with DiosMios though. It won't work on my 500GB HDD for some reason on my Wii or any of the new ones. Wii and VC backups work great, but GC backups just give me a black screen. I know I have everything set up right because I can put some GC backups on a small drive and DiosMios loads perfectly without any setting change at all on the system. I have the latest d2xv10-53beta installed to IOS 249 and 250, latest USBLoaderGX and cfgUSBLoader installed, and DiosMios v2.11 as seen from the loaders About/Credits screens. I loaded the backups to the drive using DMToolbox. I also went out of my way yesterday to do a full FAT32 Cluster size 32kb format on my 500GB drive which took about 12 hours to complete. Is it possible that it's this drive, or can I not have Wii and GC games on the same partition? Could I set up a second partition and still have all the games on one drive? Just have GC games on one partition and then Wii/VC games on the other? I'm racking my brain here and any help would be appreciated!
