Ok, I installed a 320Gb hdd in my chipped xbox. I used Hexen to set it all up. Worked fine, but drive f was only reading as 250Gb. I used xb partioner, still the same. So I used Slayer's disc to re-format and install from scratch. That works fine only I'm only getting 120B on f drive. Xb partitioner won't run cos it says the bios doesn't support it( I didn't get that error message before I used Slayer's, has my modchip bios gotten screwed up, and if so, how can I fix it?). I followed the instructions carefully, what is going on?!!
