As stated in the title, I can't access my Wii's hard drive on my PC. When I plug it in, it just comes up with 'This device must be formatted before it can be used'. I can access it with the Backup Manager, but even then I don't have access to everything. Is there a way I can back up the ISOs I have on my hard drive and then format it in a way that the Wii can read it and so can my PC? It's a WBFS and I'm running Windows 7, if it helps.
