With the Xbox hard disk conntected to your linux computer, you can just make an image by running the following line as root:
dd if=/dev/hdc of=xbox-image.raw bs=1m
Note that you need kernel 2.5 or above and a file system that supports files bigger than 2 GB (e.g. not ext2 or FAT), because the image size will be about 10 GB. It is possible to split the image into 1 GB files:
dd if=/dev/hdc bs=1m | split -b 1024m
If you want to experiment with the image contents, it might make sense to read the partitions into single files, as described in the table below. (It might be a good idea to compress the files and backup them to a CD-R. A bzip2-compressed backup of an Xbox hard disk that has never seen a game or audio CD will only be about 250 MB.)
| No split, filesystem without 2 GB limit | Split, filesystem with 2 GB limit |

| Restore single partition/s (compressed) | bzip2 -cd 00head.raw.bz2 | dd of=/dev/hdc bs=512k

This will result in the following files:
| File Name | Size | Description |
| 00head.raw | 5 MB | Disk Config Area |
| 0.raw | 750 MB | Game Cache A (FATX) |
| 1.raw | 750 MB | Game Cache B (FATX) |
| 2.raw | 750 MB | Game Cache C (FATX) |
| 3.raw | 500 MB | System Files (FATX) |
4.raw
or
4aa,4ab,4ac,4ad,4ae | 4895 MB | Music, Saved Games (FATX) |
5.raw
or
5aa,5ab | 1896 MB | unused/empty |
If you want to extract data from the FATX partitions stored in single files using the program xboxdumper , you will have to modify the array partitionAddresses[] at the beginning of the file main.c as follows:
u_int64_t partitionAddresses[] = { 0, 0, 0, 0, 0 };
Now always pass the corresponding image file to xboxdumper as a parameter, for instance:
./xboxdumper list 3 3.raw
