Using a Large HDD (10TB+) on Wii U with Separate GameCube /
Wii / Wii U Partitions
TL;DR
This guide covers setting up a single large HDD (I used 10TB, but this
scales to other sizes) with three separate partitions on a modded
Wii U:
- GameCube games (FAT32)
- Wii games (FAT32)
- Wii U games (WFS, formatted by the console itself)
All coexisting on one drive, all working through Nintendont / USB Loader
GX / the Wii U’s native game system. This requires bypassing the normal
2TB limit that both the Wii and Wii U impose on external drives, using a
USB-SATA bridge that can emulate 4K logical sectors.
Before doing any of this, go read
wii.hacks.guide and get your
Wii U and vWii properly modded first. This guide assumes that’s already
done and focuses specifically on the large-drive partitioning problem,
which isn’t fully covered there.
