anyone willing to help getting xbox360 formatted drives mount under linux?

[MastaG]

Hi there,

I was looking into getting the internal hdd to work under linux.
Since there is already a working sata-bus driver the drive gets detected but partition table and fatx support aren't available.
I've been looking into some xbox1-linux patches and found the following:

Xbox1 partition table support in 2.6.16:

I don't know how much modification would be needed in order to support the mapping of the third partion since it can be any size if it's formatted with XBR/freeBOOT.
According to free60.org:

Address            Description                                      Format
0x80000            Cache Partition                                 FATX
0x80080000       Game Cache Partition                        STFC
0x120EB0000     Xbox Backwards compatibility drive     FATX
0x130EB0000     Main Xbox 360 Partition                     FATX

The fatx patch is a little large to post.
I couldn't find any info regarding the differences between fatx formatted partition on the xbox vs xbox360.

I'm not sure if you've read the free60 article, but just to make sure: http://www.free60.org/FATX
There is a link on that page to a Kernel Module for FreeBSD, but dead dl links. You might be able to mess with that code as it references 20gb, 60gb, and 120gb drive sizes.

I found everything sitting in a weird "svn"-ish reposiory here: http://p4db.freebsd.org/depotTreeBrowser.cgi?FSPC=/depot/user/rene/xtaf&HIDEDEL=NO

Hope that helps.

[littlestevie360]

the difference is Endianness xbox 360 is big endian while xbox 1 was little endian looking at the fatx magic should be enough to show the difference (xbox 1 is XTAF)

I haven't actually tried this yet, but I found this when I was looking for a way to do mount in linux http://code.google.com/p/x360/

[nevernow]

I hadn't even considered connecting my "proper", FATX drive to my Linux PC, now I tried and it doesn't receive a /dev/sdX device - it spins up but that's all. Am I missing some USB or udev quirk? I am using a 3rd party 360drive-to-USB adapter, by the way.

[Coniger12]

try "fdisk -l" and lok for any devide without a valid partition table.

cool, had no idea that that existed

Thanks! That was it. I tried mounting it and it worked.
This is the progress of the project as reported in the latest SVN revision ( not directly visible on the web page), 18:

FEATURES

Directory Listing:     90%              multi-cluster directories can be listed but not modified (untested)
File Stating:            60%              name, file vs directory, and file size are supported; time is weirdly supported
File Creation:         100%             Creates an entry in the directory table and allocates a cluster for use
File Reading:          100%             full file read support with error-checking
File Writing:           100%             full file write support with error-checking
File Renaming:         50%             Renaming across directories (moving) is not supported.
File Truncation:      100%             Truncating allocates/frees clusters appropriately
File Deletion:         100%             Marks directory entry as 'deleted' and frees clusters
Directory Creation: 100%             Makes 100% genuine directories
Directory Deletion:   50%             Believe it or not, you have to actually remove all the files from a directory before deleting it (I thought that file managers did that automatically, but I guess not)
Partitions:                5%              partition 3 support only; automatic size detection
Multi-User Support:  60%             mounted files have user's uid/gid as owner uid/gid; user can set arbitrary uid/gid for owner

Were you able to create files on the drive? It thinks there's no free space on my 160GB XBR drive.

[nevernow]

Same here. I'm not too familiar with the FUSE filesystem, but maybe there are some tweaks to do. Also, I'm afraid memory handling needs some attention. I tried:

Code:

du -h --max-depth=1

and memory usage quickly jumped to 83.8% of my 4GB of RAM.

Hey,
Did anybody got it to compile @powerpc ?

[gnome_u_didnt]

Old topic but thought I would ask...Can we defrag the three60 fat drive in linux once it's mounted? "fsck -a" Will attempt and if successful work on app to automate. 1tb internal drive has become fragmented slow and skipping. Must be due to FAT filesystem.

[Isaac356]

Hi,

I know this topic is old, but I just thought I'd say that there's a new version of x360 on Google Code. It's a complete rewrite, and it's performing much better than the old one. I think that it would compile on PowerPC, but I don't have an exploitable 360 to test it on. It's read only, though, for the time being.
