Formatting Overview

For HDDs

*Formatting of this device type is at binary level. Therefore, if this device already has an underlying file system, such as NTFS or FAT32, formatting will fail. Make sure you get rid of any existing file systems before using the FATXplorer formatting tools.

There is a big mess of confusion revolved around FATXplorer’s formatting tool and using it to create custom HDDs. First off, you cannot just take any HDD, format it, stick it into a retail Xbox 360 console, and expect it to work. Click here to find out why. The main use of FATXplorer’s formatting tool is to reformat existing retail HDDs or format new hacked (JTAG or RGH) HDDs.

FATXplorer will allow you to create all possible partitions with custom cluster sizes.

For MUs

*Formatting of this device type is at binary level. Therefore, if this device already has an underlying file system, such as NTFS or FAT32, formatting will fail. Make sure you get rid of any existing file systems before using the FATXplorer formatting tools.

You can’t really create new memory-units, so there is no need for any specific information here.

Information Tidbit: Microsoft disabled support for Datel’s larger MUs in the 9199 Xbox 360 system software update. So even if you managed to create a larger one, it probably will suffer the same fate if it is not an official size (64 MB, 256 MB, 512 MB).

FATXplorer will allow you to create all possible partitions with custom cluster sizes.

For IMUs

*Formatting of this device type is at binary level. Therefore, if this device already has an underlying file system, such as NTFS or FAT32, formatting will fail. Make sure you get rid of any existing file systems before using the FATXplorer formatting tools.

It is possible to replace internal memory units with a different, larger storage device. Here is a tutorial. FATXplorer can format your device in preparation for usage as this kind of device.

For USBs

FATXplorer can format USB devices to FATX specifications. USB formatting works by creating files on it that, when combined, represent a full FATX device. It doesn’t format the USB at binary level like other formatters. This is done so you can still use the USB for your daily needs. These files are placed in the Xbox360 folder on the root of the USB. By default, the Xbox 360 console sets the folder’s attribute to hidden, but FATXplorer makes it visible for your convenience.

FATXplorer can create Xbox 360 content storage anywhere from 16 KB to 2 TB. There are, however, limitations you need to be aware of when formatting your USB.

Proof of concept large USB.

Proof of concept small USB.

It is recommended that you run the formatter on modern operating systems. (Windows 7 or newer) You can use it on Windows XP and Vista, but the formatter will require a forced manual eject upon completion. This only applies to the USB formatter.

It should be noted that this formatter can format “bad USBs”, which are USBs which fail the Xbox 360 performance tests. While not recommended due to obvious reasons, FATXplorer will let you format those kinds of devices.

On retail Xbox 360 consoles, you can only utilize the 16 KB to 32 GB size range. Anything higher will not be recognized by the console due to a size limitation.

On hacked (JTAG or RGH) Xbox 360 consoles, you can use the Console USB Patcher (a wizard in FATXplorer) to create a DashLaunch patch to enable larger USB sizes. The patch removes the size limitation and will allow you to use anywhere from 16 KB to 2 TB. It also removed the limitation of 2 USB ports. You can now use up to 5 USB ports for content storage.

FATXplorer will allow you to create all possible partitions with custom cluster sizes, but the Content Partition cannot be customized, and is required.
