I have been getting this error lately and i am not quite sure why. Original i had a 4.2u wii running Cios v14 and Hermes V4. All was well and Wad Manager Multimod v3b was running just fine. Eventually i decided to upgrade my custom ios to V19 and Hermes V5. Next thing i know i am getting Error -1 errors when i try and look at my Hdd that is formatted to Fat32. Well after some research i decided it was Cios v19 as it does not play nice with wad manager type things. I went to V18 and then V17 and still error -1. I do have Priiloader set to block disk updates. If that has anything to do with this i do not know. I guess tonight i will go back to Cios v14 to see if that fixes my issues. Does anyone have any incite into what i may have done to create this issue when it was not there before. If so any info to fix this issue would be greatly appreciated.
