These drives have proven to fail regardless of formatting, Y-cables, or USB ports. The controller chips simply refuse to handshake with the Wii’s USB stack.
These drives are technically compatible from a controller chip perspective, but the single USB port on the Wii cannot spin them up.
| Brand | Model | Required Cable | Notes | | :--- | :--- | :--- | :--- | | Western Digital | My Passport (2020+) | Y-Cable | Modern WD drives draw more power. Use red port for data. | | Seagate | Backup Plus Slim | Y-Cable | Works 100% once powered correctly. | | Toshiba | Canvio Ready (2018+) | Y-Cable | Canvio Flex models often fail; stick to “Ready.” | | HGST | Touro Mobile | Y-Cable | HGST is now owned by WD; same behavior. |
Best overall pick: Western Digital My Passport Ultra 500GB (USB 2.0 version) + a short USB extension cable.
Cheapest reliable option: A 64GB SD card (ignore USB entirely). USB Loader GX actually runs better from an SD card in Slot 1 than from a cheap USB stick.
Remember: If you are buying a drive specifically for USB Loader GX, search eBay or local shops for "Old USB 2.0 External Hard Drive 320GB." They are cheap, plentiful, and work 100% of the time.
