I am using Hermes v4b on a minimus AVR. I have tried with open manager 1.17.2 and Gaia Manager latest version 1.04.1. It gets to either 4.10gb or 4.66gb and then halts on copying. I have to then quit and it asks if I want to delete the incomplete/bad dump.
I have successfully backed up all of my other games including the other two Ratchet and Clank games. Why do you think I have issues with this one? I have cleaned the disc several times and there is not a scratch on it.
