I had other post's on here about my xbox HDD not unlocking. After reading various threads I managed to get ATAPWD working. I managed to get the xbox HDD to have these attributes S E L F X V + - - - - - Ater running xboxhdm and them checking ATAPWD settings were as above I pluged the HDD into the xbox nad when it boots up I get these error messages boot up with no game ERROR 16 boot up with original game ERROR 5 boot up with slayer disc ERROR 16 if a hot swap is an option, I'm getting the big green X with audio sound, ( there is no MICROSOFT in white letters under the x) I may also have a chance of getting another xbox unmodded if that would help any advice would be welcome
