Please help me get passed 137Gb

Please help, I have upgraded to a new Hitachi 160Gb hard drive in place of the old Hitachi 80Gb and I cant get passed 137Gb, I have read loads but I cant see what I am doing wrong.
After booting from my EvolutionX disc and formatting the drive the settings show:
C: 524.189.696
E: 5.118.738.432
F: 129.403.191.296
X: 786.300.928
Y: 786.300.928
Z: 786.300.928

My xBox is version 1.4
The mod is just the eprom on a headder, a few wires and a switch, I think they call it a cheapmod.
ExolutionX is Build 3935
My BIOS has been flashed with M8, with LBA Support set to “Partition 6 Takes Rest of the Drive” and Ignore Hard Drive Partition Table” unset, before flashing I checked these settings using Evtools

Some of my my evox.ini settings are:
[Misc]
UseFDrive = Yes
UseGDrive = No (I want 1 big F Drive)

[Menu]
Section "Install Menu"
{
Item "Install New drive",@210
Item "Lock Harddisk",@211
Item "Unlock Harddisk",@212
Item "MS Dashboard",ID_MS_Dash
Item "Reboot",ID_Quick_Reboot
Item "Power Off",ID_Power_Off
}

This is my 1st xBox so can anyone please help me

 

Download Slayer's auto installer and bur it to a disc it has all the essentials for evox to make it see the extra gigs and stuff. And it also has some cool programs with it. Hope this helps.

 

You just need to format a G partion.

 

I have tried formatting G but I get G: 0 bytes
Could it be that the BIOS that I have needs to be opened in Evtools and then re-saved before flashing again?
