A 32-bit LBA system can theoretically address up to 2^32 sectors (approximately 2.2TB). In practice, however, the Xbox kernel and BIOS struggle to initialize volumes beyond 2TB.

If you simply take a 4TB or 8TB drive, format it as FATX via standard methods, and install it into your console, you will encounter:
