Wiggo. After you lock your HDD, go back into the evox setting menu. There is an option that will say if the hdd lock is enabled or disabled. What does it say?
If it is indeed locked, it is your dashboard (although, the error indicated that already). You have to find a replacement MS dash. Slayers Auto-installer should have it if you can find it.

Evox hacking crew made an accident in allowing their halo 2 trainer to be played over network games. They said they won't allow network cheats in furture games. Basically, xbc could have many cheaters in it with super jump and whatnot. X-link has already been ruined if I recall. There was a big thread about it on xbox-scene. I used to play on xlink before this happened. I myself have never come across any cheaters, but it wasprobably because I have xbl.
