The Xbox uses a hard disk partitioning scheme that is hardwired into the kernel. The hard disk consists of a header, 3 game cache partitions, a system partition and a data partition:
| Offset | Size | Description |
|---|---|---|
0 MB0x00000000
|
0.5 MB | Disk Config Area This partition contains no filesystem. Various configuration data is stored on fixed offsets. Linux device: none
|
0.5 MB0x00000400
|
750 MB | Game Cache A (Drive X:) FATX volume containing temporary data of a game for faster access. Linux device: /dev/hda52
|
750.5 MB0x00177400
|
750 MB | Game Cache B (Drive Y:) Linux device: /dev/hda53

|
750 MB | Game Cache C (Drive Z:) Linux device: /dev/hda54
|
2250.5 MB0x00465400
|
500 MB | System Files (Drive C:) FATX volume containing menu code, graphics, sound, DVD player, music import, ... Linux device: /dev/hda51

2750.5 MB0x0055F400
|
4895 MB | Data (Drive E:) FATX volume containing saved games and imported CD audio tracks. Linux device: /dev/hda50

|
1896 MB - 130 GB |
Unused/Additional (Drive F:) The first xboxes had a 8GB disk, later versions came with a 10GB disk. This the space difference between the two and not used. Some tools allow it to be used as additional FATX filesystem Linux device: /dev/hda55 (only present if signature of formatted FATX found)Linux assumes that all remaining space on the disk belongs to this partition unless another FATX filesystem is detected at the LBA28 boundary. See below. |
137 GB0x0FFFFFFF
|
remaining space | LBA28 (Drive G:) If you install a very big disk some tools are limited by the LBA24 boundary. The drive G allows this space to be used in a separate drive, only accessible to LBA48 capable tools and BIOS'es. Linux device: /dev/hda56 (only present if signature of formatted FATX found at LBA24 boundary)Linux assumes that all remaining space on the disk belongs to this partition. |
This table has been completed by Markus Baertschi with lots of stuff. There might be errors and misconceptions, caveat emptor !
