## SD Preparation {docsify-ignore}
We will now place the required CFW files and some additional homebrew files on the SD Card.
?> **Notice**
Your SD Card will need to be formatted as FAT32. If your SD Card is not formatted to FAT32, use [GUIFormat ](http://ridgecrop.co.uk/index.htm?guiformat.htm ) with 32k (32768) allocation unit size to format it. </ br > **Do not** label the SD Card as `wiiu` or it will cause issues with homebrew.
?> **If you have an existing legacy CFW setup** </ br >
For **CBHC** users: go to the [Uninstall CBHC ](../uninstall-cbhc ) page to uninstall CBHC. </ br >
For **Haxchi** users: uninstall the Haxchi app from Data Management in the System Settings app. </ br >
For **Mocha CFW (Indexiine)** users: go to the [Uninstall Indexiine ](../uninstall-indexiine ) page to uninstall Indexiine. </ br >
