Video game preservation relies heavily on the accuracy of digital backups. For the Xbox 360, two primary formats dominate the scene: standard scene rips (often in XGD2 or XGD3 ISO format) and Redump ISOs.

To truly dump a game to the Redump standard—including the , the Permanent File Identifier (PFI) , and the Disc Metadata Identifier (DMI) —you need specialized hardware that can see the disc the way an Xbox 360 console does.

Even CHD files retain the original Redump SHA-1. Run a verification tool to ensure your compression didn't introduce errors.

Using a compatible LG or Hitachi drive (firmware flashed), you can use or ddrescue to create a perfect dump. Command example (Linux):

Understanding why Redump is superior requires looking at how these two formats handle the complex data structure of an Xbox 360 disc. What is a Redump Mirror?

Before Redump became popular for the Xbox 360, the scene was flooded with:

While "Redump" is a preservation format, you usually don't play the raw .iso file.

The Xbox 360, released in 2005, is an aging console with a finite lifespan. As the years pass, the risk of data loss, corruption, or obsolescence increases. The Redump project addresses several pressing issues:

If you want to move beyond messy downloads and maintain a set:
