Partitions

The Xbox hard disk contains multiple partitions. Unlike a PC, which typically contains either a Master Boot Record or GUID Partition Table to specify the partition information, the Xbox kernel uses a fixed partition layout. The file system used on the Xbox is FATX, a variant of FAT16/32 developed by Microsoft specifically for the Xbox.

Drive Letter Description Offset (bytes) Size (bytes) Filesystem
N/A Config Area 0x00000000 0x00080000 Fixed Structure
X Game Cache 0x00080000 0x2ee00000 FATX
Y Game Cache 0x2ee80000 0x2ee00000 FATX
Z Game Cache 0x5dc80000 0x2ee00000 FATX
C System 0x8ca80000 0x1f400000 FATX
E Data 0xabe80000 0x131f00000 FATX

FIXME:

  • Add info on how extended partitions are added.

Locking

The hard drives in the Xbox are locked with a key which is unique to the specific Xbox. The drive is unlocked by the kernel at boot.
