GDI images are "lossless" dumps—they preserve every single byte of the original game data, including any error-correcting codes and low-level sector information. For this reason, GDI is the format of choice for preservationists and is the standard used by the , a community-driven initiative dedicated to creating perfect, verifiable disc dumps.
