When i try to boot anything at all off of the External HDD it says that error. Even Freestyle Dash, or Dashlaunch does this. I've tried reformatting the Ext. HDD and it does that samething.

Specs:
Xbox -
RGH Slim
Trinity Motherboard
Type 2 Glitch
Default Memory - 60 Gb

Ext. HDD -
Western Digital
3 Tb

I'm thinking about trying to hook the Ext. HDD up inside the RGH if i cant get it working.

Thanks for any help at all.
