## Dumping and Installing Wii U Discs

::: tip

Installing a game to the system memory (NAND) is not recommended as it's limited to either 8GB or 32GB depending on your model, making you run out of space pretty quickly if you want to install multiple games.

:::

::: tip

When installing a game to a USB device, we recommend that you use an HDD and not a flash drive, as those are not optimized for constant reading and writing, therefore making them fail quickly. 如果你的 HDD 没有外接电源，则你需要一根硬盘 Y 形线将硬盘连接至 Wii U 上的两个 USB 接口上。

::: danger

In order to install to a USB device, it has to be formatted by the Wii U. Doing this will erase (delete) all contents (documents, pictures, videos, PC data) off of it, and prevent it from being used on another system unless you reformat it. This _does_ include the vWii, meaning you will not be able to run Wii and GameCube disc images off the USB using USB loaders. To format, plug your USB HDD into the Wii U, power on your Wii U, your Wii U will prompt you to format your HDD. Confirm with Yes.
